Which SMS confirmation provider should I choose?

Question

SMS

Have a good day everyone! :)
We asked ourselves the question of implementing the confirmation of operations by SMS - an SMS with a one-time password is sent to the phone, which must be entered into the web form to complete the operation. SMS will need to be sent worldwide - Latin America, the Middle East, China - these are 80% of all our customers. Number of sent SMS up to 1000/month.
Who uses what services or heard? Reliable and widely known are needed.
Thanks in advance!

Answer 2

Twilio as an option. Worked with him for quite some time. There were some small problems with the delivery of messages, but they are rare and pass quickly.

Answer 3

I have been happily using SMSintel for three years . Convenient PHP-class and different crap for 1s and other things. Delivery is reliable, I use it on a serious project, there were no complaints. Enjoy!
