What to do if SMS do not arrive?
If you have purchased a mobile number with the SMS reception feature and activated it for at least 3 months, make sure that SMS reception is enabled in your personal account. To do this, go to Personal account - Services - SMS - Incoming SMS and check the box next to «Receive SMS».
If everything is set up correctly but SMS messages are still not arriving, please contact customer support. Create a ticket specifying the sender's number, the date and time of sending (with the time zone). Customer support will check the message status and help determine the cause of the problem.
