At low volume, they might be more attentive to you when compared to twilio. US,canada pricing is low.
Everything else. When you are not a customer, your sales queries will get resolved really fast, but when you become a customer, you will not get reply. This happens because once you have integrated your system with plivo, the changes that you will move to twillo is low and the plivo guys very well understand this.
To start with there a lot of countries where the number pricing of plivo is higher than twillo. The mobile SDK of plivo is not very good. You will spend months with your developer trying to solve the bugs, ultimately to find out the issue is with plivo. To add to it, sometimes to numbers don't work. As we run telephony system, we sell the number to our customer, it will not work, and then we have to replace it. It reflects really bad to our customers who dont understand the fault is from plivo.
The casualty of the company is to the point that different pricing is shown in when you download the pricing excel, the website has a different price and the developer application has a different price for a few countries.
