I recently switched four phone numbers to Public Mobile. On two phones, messages are not working, and I am unable to send or receive messages. What could be the cause of this issue?
If I cannot get help, I will have to change provider again.
@BladeMaster if you have an iPhone, go to Settings> Phone > My Number and remove the phone number manually. Reboot and go back to the menu to enter the phone number, this is re-register iMessage
