My partner and I unlocked and switched over to T-Mobile last week. As was suggested on this forum, we went to a T-Mobile store and told them we needed two sim cards with talk, text, and the $10 unlimited internet for our Motorola Razrs that we had charging at home. After a few successful days, my partner suddenly was unable to send or receive calls. (When someone calls him, we get a message that says "all circuits are busy" even though he has 5 bars and his phone is right next to mine which has no issues). It happened a couple of days ago and we called T-Mobile support and they weren't able to fix it, but then the next day it was fine. Now he is having the problem again. When dealing with T-Mobile support we are running into an issue by insisting that the phone is a Motorola Razr with the fear that if we admit it is an iPhone they will tack on that extra $25 or $30 package that we supposedly don't need. But with this last call to T-Mobile support they started getting into instructions specific to the Razr including wanting a number off the back. Should we go ahead and fess up that we are using the sim card in an iPhone?
