I decided to switch from straight talk to T-Mobile prepaid. I paid for a month of service and received a Sim card. I wanted to port port my number from the previous service and T-Mobile said they could. The new sim can make a call but not receive one. Can use data just fine. Cannot send or receive texts or MMS unless it's from T-Mobile. This morning I got a T-Mobile text saying there was a problem porting my number and that they'd call me, however this Sim cannot receive calls. What do I do? I called them and they said they would port it and that my issue was that the PIN I gave them was incorrect. They asked for the correct PIN, but I NEVER made a PIN or provided one. This whole thing is a mess and every call goes exactly the same.
