"Easy to setup and use in a very short time"

What do you like best?

I liked how transparent and easy it was to setup the whole process. We included a message sending feature to our business in little less than a day of work (plus a few more hours for debugging)

What do you dislike?

The website could be more "modern", and there could be a better debugging assistance when trying to figure out what is wrong with the messages.

Recommendations to others considering the product

1) Improve interface. Try betting on a UX/UI designer and better frontend developers

2) Supply strong debugging capabilities. It largely reduces the setup times in teams with lower technical capabilities.

What business problems are you solving with the product? What benefits have you realized?

Our problem is that of many merchants: receiving online orders without completion. That is, customers add products to their carts and then don't actually buy anything, or in some cases don't pay (for example when the pick a bank transfer payment method). We needed to remind them about having an open order to pay, or products in their carts reserved for them.

"Perfect service for my multiregional company"

What do you like best?

Ease of implementation. We needed less than one month to go live. You don't need several or deep knowledge of programming to make a successful integration with Nexmo. It's really easy to understand how to achieve the connection.

What do you dislike?

Nothing so far. The service is very complete. I would take the same decision if I would need to integrate other system with SMS world-wide provider.

Recommendations to others considering the product

Very complete service and easy to implement. You can send SMS to all around the world easily and no expensive. If you want a plugin connection and a reliable service, you have to connect to Nexmo.

We need less than 2 days to have our system fully operative, and since then it's very stable.

We tried several options in the market before to know about Nexmo, and we can subscribe that Nexmo is the best one.

What business problems are you solving with the product? What benefits have you realized?

I can integrate several countries with the same product. In addition, the price of the SMS is really competitive in almost every country is offered. You can build a business model with low or zero impact, because the price is really affordable.

"Nexmo is the best partner when it comes to Mobile / SMS reachout to our clients"

What do you like best?

We use Nexmo SMS API, to reach to our clients in order to perform transactional operations to our business, like registering their personal info or evaluate our services. This is what they do best. Their API is quick and efficient plus the support in GitHub is very helpful.

What do you dislike?

Nothing yet. Of course I haven't used all their services, but what we use so far is very good.

Recommendations to others considering the product

If you want an easy set up SMS API, Nexmo is your way to go. It was the first company that we co-operated with this kind of setup and they full delivered. Of course, if they keep up doing the same, we will keep trusting them with our work.

What business problems are you solving with the product? What benefits have you realized?

We had very poor opening rates in our transactional emails. With Nexmo SMS API we contact our clients directly to their phone and message is delivered in much better success rates.

"Simplistic API and wide array of services"

What do you like best?

First and foremost, the API - that requires very short learning curve to implement. The fact that verifications are performed directly within Nexmo adds an extra layer of security.

The dashboards are intuitive and easy to navigate. Number verifications work with 99% certainty (except in some rare cases where texts fail to reach).

What do you dislike?

Inability to set sender ID unless over a substantial volume on SMS-es sent / month. This can possibly be provided as an add-on (paid) service for those who don't reach the volume.

What business problems are you solving with the product? What benefits have you realized?

End-user mobile phone verification and assistance in password resets through self-service. This serves dual purpose :

1. As an alternative means of verifying identify during password reset process

2. Keeping the mobile numbers database up to date - which otherwise is a notoriously difficult process as end-users tend to ignore update requests.

"Nexmo is our SMS platform"

What do you like best?

Super Easy Integration to our CRM system (Zoho CRM). Nexmo is connected to our backbone CRM and allow us to send SMS and notifications to our users and customers. We realised our users don't read emails but they do read every SMS.

What do you dislike?

We are unable to mass SMS users for marketing purpose. The Nexmo plugins doesnt allow mass SMS.

Recommendations to others considering the product

If you are looking to integrate a SMS platform into your CRM, Nexmo is the perfect solution

What business problems are you solving with the product? What benefits have you realized?

We have finally solved the communication issue. When a customer purchase a service on our website, we immediately send them an SMS via Nexmo and that allows us to notify immediately that his purchased service is available. We do also send emails ... but emails get lost, go to spam filter or simply are not read.

"Quick setup and excellent support"

What do you like best?

Sandbox is very cool, easy to use and dynamic. Very reliable and low latency.

Time of response is really good overall. The SMS delivery responds within seconds.

There are a lot of real time statistics that can help you analyze information on a managing level.

The phone verification check is really cool to validate if a sign up on the website is genuine.

What do you dislike?

Sometimes the customer service is not what you would expect for the price you are paying, but it's been getting better over time. As with every platform, it has a lot of ways to get better, and just to name a few the metrics from sent SMS's could be highly improvable.

Recommendations to others considering the product

Great product! We are really happy with all the features that we used! After investigating several options that were in the market, Nexmo was the one that comply with everything that we need at a fair price! We are sure that we made the right choice, and surely in the future we may be using some of the features that we are still not using!

What business problems are you solving with the product? What benefits have you realized?

Mostly for app activation and communication with customers in real time. A single API that can send worldwide SMS it's a must have. As said, the support team has been getting better over time, which have helped us every time we have an issue. Getting connected with our customers through our B2C is really easy with Nexmo!

"Nexmo is a very good sms platform"

What do you like best?

Nexmo is a very good sms platform that we use to send sms to our customers.

We like the ease of deployment. Anybody can connect to Nexmo because is pretty easy and you can find a lot of help in the website.

The time of response is really good. You don't have to wait a lot of time to ensure the sms delivery, it responds in seconds.

You can connect any kind of technology with this solution because of the portability of Nexmo.

What do you dislike?

I really don't have any issue to complain about. The prices are not the same for every country but we know that is because of market in every region.

Something that can be improved is the report of the sent sms. It's actually a little confuse and can be more detailed.

Recommendations to others considering the product

Nexmo is the best platform in the industry for sure. We don't use all the features that the api provides but we are really satisfied with the ones we use.

We are sure this is the best solution in the market if you need to solve the communication in real time with your customers.

When we have to build a new web site we are going to support the solution with nexmo.

What business problems are you solving with the product? What benefits have you realized?

we can communicate with potential customer in batch easily. In our ecommerce we need to send some information to our actual clients and we can do that now with the support of Nexmo.

We have the certainty that the message arrives in real time.

"Quick to Setup and Easy to use!!"

What do you like best?

We loved the ease of setting up the account and the great assistance provided by Team Nexmo.

The Language support and the ease of integrations is quite amazing with the ability to integrate with their APIs. The class of support provided by the SPoC at NEXMO is worth a mention as I have not come across any SMS provider going out of the way to ensure all is set for a smoother rollout of your deployments with an SMS provider. I also received quite some free credits from the Support team to cary out testing and that was quite a gesture to tell that they cared more about the customer than the mere price.

What do you dislike?

Not any thing as such.

Would surely have loved better visualization of the metrics captured from sending the SMS. Also I suggest that you look into the way the Search messages/Analytics features are designed to provide easier use.

Recommendations to others considering the product

One of the best in terms of the Support vs Pricing. I did a fair bit of research and have experience with other international providers like Nexmo and found them to be better in terms of the reliability of their platform and services.

What business problems are you solving with the product? What benefits have you realized?

We use Nexmo on a daily basis to send Promo and Transactional SMS to our Client's customers. The real time APIs enable a seamless connectivity between our systems and Nexmo. We use it for our enterprise customers on a regular basis to send out SMSs and I figured out that the delivery rates are over 98% as against my earlier provider where it was about 95%. This ensured better response rates for most of our Surveys administered via SMS and increased the volume of the responses by a little over 3%.

"Nexmo provides high quality of service and excellent support."

What do you like best?

The quality of service is Nexmo's is what makes Nexmo great. I have been impressed with the delivery rate to international mobile carriers which has left our customers very satisfied. The support has been excellent. the support team is very responsive and knowledgeable. Nexmo support can find a resolution for an issue rather quickly. Nexmo also provides a great amount of documentation which is very useful.The statistics are a great feature. You can get real time statistics with Nexmo. That's something many SMS provider do not have.

What do you dislike?

The rates are higher than I would for an SMS provider. But Nexmo can assist their customers in special cases. When starting the service you can only prepay which makes things a bit clumsy. We had an issue with the payment processor not accepting credit card payments after while.

Recommendations to others considering the product

Excellent service if you seeking a high quality SMS provider.

What business problems are you solving with the product? What benefits have you realized?

We have a customer requiring 2FA for a special application. Nexmo's service provide the ability for us to provide the service an meet out customer's expectations. Nexmo's service works well.

"Developer Unfriendly"

What do you like best?

Call routing logic seemed to work once I figured out their key + secret + private-key-for-each-developer-app (?!?) authentication.

What do you dislike?

I write this review while I'm waiting on the latest response from Andy Li, in a 6-hour-long nexmo support email thread. I just want to give them money (they only allow you to add money in 10-euro increments -- you have to email support to change that amount, or to set up automatic payments). They apparently require you to answer several questions about who you are and what you plan to use nexmo for, before they remove payment restrictions. At no point during their onboarding documentation do they say you'll be held up for hours waiting on permission to give them money easily.

This is ridiculous -- I don't know of any competitor who puts this kind of friction in front of you giving them your money:

"At Nexmo we like to take good care of our customers, and there are several measures in place to protect our customers’ identities and our own platform from inappropriate use, of which the top-up limit is one. In particular, if you could share the following it will allow us to remove the limitation from your account more quickly:

Company/service web address

Nexmo services you intend to use

Geographies in which you intend to use these services

Content type you expect to be sending and in what volumes

Social Media content that links you to your company, e.g. LinkedIn page link"

Recommendations to others considering the product

Take a hard look at the billing page before diving too deeply in. It's not like they'll just let you pay $100 and you can start using that credit. You have to pay in 10 euro increments! Or maybe you'll end up stuck in several hours of emails like me.

What business problems are you solving with the product? What benefits have you realized?

Nothing. Dead in the water. We're moving to a competitor, it looks like.

"An almost perfect service"

What do you like best?

I loved that its

Flexible: We've been able to design our entire booking system on top of their SMS and VOICE services with massive customizations to adopt to the bottom of the pyramid market

Affordable: Their pricing is super friendly for medium and small enterprises

Support: CUstomer support is top and I always feel like I can rely on quick responses which few software companies provide.

What do you dislike?

Because nexmo works with local telcos, sometimes their services are subject to the changes/updates/upgrades these local telcos make. As a result, the solutions you've built on top of their technology while reliable is vulnerable to the local telcos. I am a user in Southeast Asia so I face this issue, but that being said, their support is always on top of things to help sort out any issue!

Recommendations to others considering the product

if using for southeast asia, run smaller tests to see reliability of service as local telcos often can become unreliable, not Nexmo per se.

What business problems are you solving with the product? What benefits have you realized?

I am using nexmo to target non engish speaking locals in southeast asia to communicate via SMS and calls with users around the world via our travel platform where we sell unique local activities by locals to toursis. Benefits are we have managed to break down communication barriers and bridge the gap between non English speaking locals and travelers to this part of the world.

"Simple and reliable"

What do you like best?

The SMS service is by far the easiest to use, simple API tools available, and priced very reasonably. Documentation is complete, and they provide (nearly) everything you need to be fully self-managed.

What do you dislike?

The built in dashboard doesn't expose all the features the API allows, so you have to write your own for full access.

Recommendations to others considering the product

If you need a simple SMS service, this should be your only choice.

What business problems are you solving with the product? What benefits have you realized?

Sending SMS alerts used to be handled in house by connected devices which were unreliable and expensive to replace. Nexmo has taken a big headache away from the operations team, so much so that we hardly even think about the impact of sending thousands of SMS messages.

"SMS api is good for low throughtput, needs extra work for high sms volumes"

What do you like best?

SMS API has many countries and networks available, They provide clients in a lot of programming languages, although they need work for higher volume. Customer support is good, they provide different set of api keys for testing/staging/development. Admin interface is easy to use and access can be allowed/removed to employees accounts so no need to share username and password with people to give access.

Inbound SMSs work well and never give us problems. We also use Number insight to remove landlines and invalid numbers from our system.

They also have a voice API but we haven't used it.

What do you dislike?

SMS API only supports sending one SMS at a time, and it's rate-limited, meaning you need to think your infrastructure to queue the SMSs and send them at a rate below the limit. Some client libraries they provide don't reuse http connections, so you might need to implement your own if you have high volume.

Recommendations to others considering the product

Great, specially if you don't have high volume

What business problems are you solving with the product? What benefits have you realized?

Sending mass SMS campaigns to many users. They work but are tricky to scale to high volume.

"Good/cheap service which takes forever to fix it when its broken. Works well when it works."

What do you like best?

Good pricing and coverage. Good API. Improvements in their website which makes it a bit more usable than it was couple of months ago.

What do you dislike?

Support takes forever to fix any issues. (numbers out of service). Sometimes it takes over 4 months. Numbers are pulled out of service for various countries without very comprehensive explanations as to what was wrong/what the reason was /etc - so you'll have to figure it out, inquire with support, follow up on the issue until you get a better answer.

Website has improved a lot but still lacks a better search for phone numbers . Editing a lot of phone numbers is horrendous and you're better off wasting the time to implement that edit via API instead of doing it via their website.

They charge in EUR currency, but the pricing on the website is in USD (might be different for Europe, i guess?) so that's a problem when you have to account for the exchange rate, etc.

Recommendations to others considering the product

Read the API docs and have patience. You'll make it.

What business problems are you solving with the product? What benefits have you realized?

Coverage in countries where i would otherwise not have access to. Some cost savings here and there.

"Nexmo is quite good third party api for implement sms and calling feature for your project."

What do you like best?

I like both features of nexmo a voice calling as well as SMS and the most exciting thing is that it also provides the number of choice of a person's voice. and another main thing which considers by all the organization is that pricing it's also cheap.

What do you dislike?

if you are .net(c#) developer then don't go for nexmo it has no sufficient documentation in c# language that's the only thing which disappointed me

Recommendations to others considering the product

Dear users,

you can definitely go for nexmo services its good and easy but if you are c# developer than think for an alternative because it's lake of documentation in c# language

"Excellent app with wide area coverage"

What do you like best?

Nexmo API covers an extensive geographical area providing a reliable SMS- based service

It is a telephony service with easy integration feature. It not only records your calls but also converts text into voice. It has feature of call control with a complex voice network covering 23 languages.

Nexmo uses Voice API which can be implemented in the existing system of a user. Moreover, its inbound messages are always free. A user only has to pay for that inventory of numbers on which these SMS is sent.

What do you dislike?

Firstly, a confirmation is required whether SMSs are sent to different networks or not.

Secondly, if a message is sent to numbers present in the NDNC (Indian Authority) list they will be blocked completely. All messages sent after 9pm will be queued up in India. Lastly, it is difficult to determine parameters in sending an international SMS.

Recommendations to others considering the product

Nexmo is a very good option to go for SMS solution as it offers you free inbound messages.

What business problems are you solving with the product? What benefits have you realized?

Its benefit is that Nexmo has designed an infrastructure platform to suit our needs. With a consistent response time we pays only for what we actually uses. We don’t had to change anything in our IT infrastructure and configurations to fit Nexmo’s APIs in our system.

Also whenever there is a high traffic, Nexmo automatically assigns the SMS in queues and then change the carrier route to make it fast.

One of the best things I found with Nexmo was the support team they have.

"Very helpful, it's a must!"

What do you like best?

Easy and cool platform, it's fast and complete! What I value most is the quality of the support as well as the service.

What do you dislike?

Some part in the UI and the boring-slow recharge method. Making the interface simpler and easier to send invoices maybe making them available immediately on the site.

Recommendations to others considering the product

Nexmo is easy to use and performs like few other companies in the industry. Ease of use and quality of support make the platform a reliable partner to work with.

The many request of sms delivery is now complete thanks to Nexmo, I can deliver a lot of sms with in a few!

"Speedy and resilient platform, integrated with other systems"

What do you like best?

It is great to be able to get our SMS messages out rapidly and to view reports on delivery by day, week, month. It is great to use this for QC'ing our SMS efforts and for reporting.

What do you dislike?

I don't have anything I dislike about Nexmo. It does what it needs to do and we have very good support from the team there. They are responsive and they have our best interests in mind.

Recommendations to others considering the product

Have a technical/implementation partner to help you with setup and with testing and with ongoing support. Make sure you are honoring your Customers' SMS preferences and the flow of SMS in the application and make sure to check in on the reports regularly especially during a large send.

"Very impressed with the out of the box features of Nexmo"

What do you like best?

The fact that there was a rest client for .NET saved us a lot of development time. Being able to simply send SMS messages and being able to clearly manage our account were big pluses.

What do you dislike?

Wish we could send a media image with text messages. We had to choose another service for customers who want to send an image. Wish Nexmo would add some Mime type support.

What business problems are you solving with the product? What benefits have you realized?

We are bridging a gap with notifications from our applications in our suite of products to alert both users of the applications as well as customers who are managed by the applications. The number of notifications we have on our list to develop is a great benefit. Shows the endless possibilities.

"Very good customer service from the very beginning from Payam Taghizadeh in London"

What do you like best?

Once a computer code writer here in Vladivostok wrote a short program to send SMS messages, everything else has been automatic and very easy to use, including refilling our account online. The Nexmo SMS sending page is very easy: just insert the message, load the address list and press a button. Great

What do you dislike?

By Russian law we are not allowed to use our own header on the SMS messages that we send, so our messages are sent out using different and random headers. Therefore we have to be sure that the first few words of our messages identify us as the sender.

What business problems are you solving with the product? What benefits have you realized?

So far we have only used Nexmo to send SMS announcements of our classical music organ concerts. Since we began, all our concerts have been completely full, no empty seats.

"Mixed experience using Nexmo "

What do you like best?

The api is decent. Documentation is elaborate too. Customer Support is fine and prompt as well. Nexmo works however...(see the next response)

What do you dislike?

Sometimes I get multiple/duplicate api notifications for the same voice call made or sms sent to a user. Also the dispatch speed of text messages/voice calls (I'm in India) is rather slow considering our platform is a near real-time system and every second of delay in delivering a text/call matters to us.

What business problems are you solving with the product? What benefits have you realized?

We are building a multi-point communication platform for individual professionals, entrepreneurs and small biz owners. More about it at www.snhyper.com

Using nexmo makes our platform multi-point as we can call up or send text when the recipient is unable to read web/email notifications.

"Nexmo SMS and T-T-S services are used for registration of users in our mobile app - Snaappy "

What do you like best?

Nexmo's SMS service has global coverage and reasonable pricing. Good quality of delivery for major regions and countries.

Nexmo's T-T-S services is one of the few in the markets and offers support for delivering message in various languages.

Nexmo provides a personal manager that can help in business matter and assist during technical problems (by stimulating the technical support team and engineers).

Overall, technical support and engineers are qualified and capable to proper support and resolution of technical issues.

Nexmo's API is well implemented and documented, which makes its integration easy into our back-end.

What do you dislike?

There've been cases when system could not reliably deliver SMS to new regions or countries, and we have to proactively detect such cases and alter Nexmo's personnel to switch or improve delivery routes (carriers).

The administrative console can be made more informative and easier to use, especially when it comes to statistical and historical reporting.

Recommendations to others considering the product

If using Nexmo for SMS delivery, then make sure you have an alternative delivery channel, as non of the services out there can guarantee 100% delivery rate.

What business problems are you solving with the product? What benefits have you realized?

In our application users are registered via their mobile phone. During registration process Nexmo SMS and T-T-S services are used for sending the registration code via SMS or voice call to the user's phone.

Nexmo SMS service is one of the three services that we use - the other two are Plivo and Twilio. In other words, we have triple redundancy when it comes to sending SMS.

Nevertheless, there are cases when SMS can't be delivered, and that is when Nexmo's T-T-S services used to deliver registration code via voice call (in various languages depending on user's phone locale).

Our developers are really much enjoying to implement your service. It is also easy to top-up and manage my account. We are really satisfied with the customer service as well, whenever we had questions, you answered extremely fast.

Nexmo is exceptionally easy to use - we were able to integrate the service with our backend and get started within minutes of signing up. Reliability is also excellent, and the pricing is very competitive.

What do you dislike?

Only minor complaint is that there doesn't seem to be a way to have PDF invoices automatically mailed to you when a payment is made - they are only available by logging in to their website and manually downloading them. Invoices are also only available 72 hours after a payment is made.

"Nexmo great SMS and Voice notification service"

What do you like best?

The API is very easy to use and integrate into your own applications.

The examples given are easy to get started with just by replacing your credentials in the examples and the pricing is very competitive.

ie. https://rest.nexmo.com/sms/json?api_key=xxxxxxxx&api_secret=xxxxxxxx&to=xxxxxxxxxxxx&from=NexmoWorks&text=hello+from+Nexmo

What do you dislike?

If I had to say I disliked anything it would be two things in particular and neither are that big a deal to me.

The number availability can be spotty at best in some places, although this has improved dramaticly as of late and there are some

Recommendations to others considering the product

Sign up, try the free credit. You will be suprised with the quality of the service.

What business problems are you solving with the product? What benefits have you realized?

I am using nexmo for a couple of projects. I wont give you details of the projects, but I can describe use-cases that are working for us.

The first is for 2-factor authentication. On login, we send an SMS that contains a code to type into the login flow. This proves that they are in possession of the phone.

The second is for notifications. We use both the Text-to-Speech service (Voice API) with prompts so the user can confirm they have received a notification, and also the vanilla SMS service.

We have found that the majority of messages come through within a few seconds (we found that other services weren't so prompt).

What do you like best?

I have been using nexmo for a year now and their customer support, sales team and the overall API in general is what made me stixk with the team. Backed by great documentation and a super simple yet full fledged API, nexmo's team helped me build my application with relative ease.

What do you dislike?

Absolutely nothing. The entire experience has been nothing short of perfect.

What business problems are you solving with the product? What benefits have you realized?

Our group calling application Patch brings unique features to the calling experience. The nexmo platform enables us to deliver cutting edge voice at the best possible rates.

"Their fraud risk system could do with an overhaul"

What do you like best?

The pricing is fair, the choices you have are wonderful. For the brief time I was able to use the service I used the API to verify if a member's signup on our website was genuine or not (by performing a phone verification check).

What do you dislike?

Fraud risk system has wrongly identified my company as high risk. We have a good reputation worldwide, registered company in the UK and have been running for more than two years. A competitor to Nexmo who we previously used and have been forced to stay with have offered an uninterrupted service to my company for a considerable time. Support was unhelpful and anonymous. From day one I got unwanted hassle from two different people from Nexmo. There's no auto reload option if the balance is low. The topup system is very restrictive compared to other competitors out there. Nexmo caused several hours of downtime because they failed to send a simple email to say that the account had been blocked.

Recommendations to others considering the product

No recommendations, avoid the hassle and find a different competitor

What business problems are you solving with the product? What benefits have you realized?

I was hoping for my company to be able to use the phone verification with Nexmo, but it seems I'll have to stick to a competitor due to their fraud risk system wrongly identifying my company as high risk.

"Great customer service"

What do you like best?

I had some special requests that I needed to contact someone to help me with. I received answers by email quickly and my issues were resolved to my satisfaction and very quickly.

What do you dislike?

I wish I could've handled my issue myself, but it was not a big deal to have to contact someone.

What business problems are you solving with the product? What benefits have you realized?

Nexmo is great for having extra phone numbers for various business purposes.

"Good support, Not the best delivery rates"

What do you like best?

Support-team SLA and attitude, and Web Selfcare portal which is awesome, and Britt Barak <3

What do you dislike?

Low and Unclear delivery receipts (some are network, some are to device - depending on network, without good documentation on which is which), No campaign management features.

Recommendations to others considering the product

Take advantage of multiple keys (both for the throttling limits and better administration). Use callbacks from day 0. RTFM regarding sending A2P SMSs in USA and Canada.

What business problems are you solving with the product? What benefits have you realized?

Sending SMSs around the world, One-Time passwords and apps invites.

"Terrible customer support and awful experience."

What do you like best?

I like when it works. Since they refuse our payment methods out of the blue. I quite hate everything about it.

What do you dislike?

The fact that they suddenly refused our Credit Card and Paypal payments (after both payment methods have been used many times over the last year); Now after failing to fund our account, Nexmo decided we can only pay using an international wire transfer which will take 3-5 business days to clear. Until then our website is crippled and our users cannot complete their registration.

"Versatile capabilities across multiple communication channels"

What do you like best?

I have the option to handle communication mediums using one single source. I especially like that they are very well integrated with Telecom providers for their SMS feature which we use the most.

What do you dislike?

It's a bit more costly than using a local provider per country. There is little feedback if something goes wrong unless you take the effort to check it yourself.

What business problems are you solving with the product? What benefits have you realized?

Making people show up at their meetings with the SMS function offered by Nexmo.

"Reliable and un-complicated"

What do you like best?

Nexmos have a very simple set of API functions in their SMS offering, the consumable costs are in-line with the best value on the Market and the availability of numbers and regions is impressive.

What do you dislike?

The SDK for PHP is confusing and has what seems to be two unfinished versions.

What business problems are you solving with the product? What benefits have you realized?

I use automated SMS to remind customers of meetings with their clients, it has reduced no-shows for appointments that cost the business an unacceptable loss.

"Bad security and unreliable service"

What do you like best?

API was easy to use, but that seems to be pretty much it. Other vendors seems to have the same anyway.

What do you dislike?

Someone broke into our account on their servers and not through our own, yet they refuse to refund our balance. We were willing to overlook this if they fixed the issue but they didn't even care.

Account managers were nowhere to be found when issue happened.

SIP service accepts connections from IPs other than our server Already a big no no for security.

.

Recommendations to others considering the product

Careful how your account manager disappears when you have issues and they are not trying to sell you new products,

What business problems are you solving with the product? What benefits have you realized?

"Nexmo just works"

What do you like best?

Simple to setup and use via API. Ability to view historical SMSs has come in handy. Auto payments mean I do not have to keep making deposits when it runs low.

What do you dislike?

I have bumped my head against the throttling a few times, but have managed code around it. It could perhaps be eased over time.

Recommendations to others considering the product

If you send large numbers of SMSs at a time you will need to use a queue and delay to avoid throttling.

What business problems are you solving with the product? What benefits have you realized?

Mass communication with users who do not necessarily use email.

"Easy to integrate with, good account management options"

What do you like best?

The ability to have sub-accounts is a must for us, we provide SMS functionality to our clients and so being able to segregate them is vital.

What do you dislike?

The UI can be a little confusing with respect to the account management, I forget the details off the top of my head but the switching options move around between various areas of the system. Sometimes top-left, other times top-right.

What business problems are you solving with the product? What benefits have you realized?

We use Nexmo for inbound and outbound SMS, enabling our clients to form better relationships with their customers, driving sales.

"Broad geographic offering but with limited services"

What do you like best?

Nexmo seemed to offer a very wide geographic telephony service, which was critical for a global SMS-based service we were developing. The API and fairly plain pricing was an added bonus. At the time, the main competitor was limited to a small handful of countries, so Nexmo was explored as an alternative.

What do you dislike?

The main issue with Nexmo's service, at the time we were evaluating and actively using it, was the quality of service promises. For example, we needed to be able to provision new local phone numbers dynamically and automatically, which was not as intuitive as we hoped. Additionally, we needed to confirm that SMSs were passed off to the various networks, which was difficult to prove with Nexmo. Nexmo's main competitor was able to provide these additional services.

Recommendations to others considering the product

Nexmo's offerings may be advantageous to groups that do not need the quality of service promises (e.g. confirmation that SMS was passed to network) we required, and are looking for a low-cost solution.

What business problems are you solving with the product? What benefits have you realized?

Ultimately, one of Nexmo's main competitors expanded their geographic reach while continuing to offer the quality of service promises we needed. We have back-up plans to incorporate Nexmo as a secondary service should we need to diversify our offering, but now rely upon the competitor for our telephony services. The quality of service promises were absolutely essential to our project.

"So far so good"

Been using Nexmo for about two years. In this time we were able to find how to best work with it and now are fully satisfied with Nexmo.

Nexmo is not expensive and is performing well for our customers all over the world.

What do you dislike?

Finding verification and why it failed can be a little tricke. Would be great to have larger log and search through intervals.

What could recommend is to check use case for you bussiness and then just do it.
