Had the same problem with an unlocked Lumia 920, now the same with the unlocked 1020. SMS is working, then suddenly I stop receiving them and can only send. Remove the SIM, insert the sim into my android and all the sms's come in. Put the sim back, SMS is working fine, an hour or two later stop receiving again and the cycle continues. I tried changing to a new sim, issue continues. Tried wiping, same issue.
