Who worked with SMS.RU, what do you think?

Question

PHP

I was looking for a service for sending SMS , I
came across SMS.ru
who used it, can you tell me how you like it?
The API seems to be the norm, the prices too,
but here are the documents and so on 10 minutes after registration ... as if something else was not thrown out later
and the topic of free SMS for developers was confused when it was written in the conditions (rules)

3. All sent messages are subject to payment.

Answer 1

Used in the project and just to send SMS. Everything is fine, SMS reach quickly, there were no delays, there were no problems.
For developers, there is a limit of 5 free SMS to your number per day.
