Which mobile operators have your service sends an SMS?
There is a support operator Tele2 Kazakhstan?
Technically, our SMS provider should send messages to every operator worldwide, but there may be some not supported operator, but we don't have a specific list.
You're welcome to sign-up for Premium, try it out and it if won't work, you can ask us for a refund.
To check if it works, please make sure you'll enter your phone number with the country and area code in this format: +123456789 (that is - with a + and no spaces or dashes) and choose one of the Canadian operators from the "Number to send from" drop-down menu.
If this won't work, send your number to firstname.lastname@example.org and then we'll be able to send 3 test messages and if none will arrive, contact our provider about it and if it turns out that they can't set it up, you can of course get a full refund.
