FAQ • Why has my message not been sent and has the status "unregistered sender id"
To send SMS messages to subscribers of
Megafon (Iota) and
MTS operators, it is necessary to have the sender's own name registered with telecom operators on a
paid basis.
Beeline and Tele2 operators do not require mandatory registration, just create a name in your personal account.
You can submit a name for registration in your personal account, Settings menu -
Names of senders, when creating or editing a name, you need to select options for operators.
