I've read several of the previous call blocking threads but none seemed to have the solution I was looking for. I used the general call blocking option in my phone book, and ended up deleting the phone number from my actual contacts list. I then re-entered the number back into my phonebook, and took off the block calls option, but it still wont allow the caller to call my phone. He says he keeps getting a busy signal or it goes straight to voice mail. he can still send texts. Is there a way to fix this? Or do I need to call tmobile about this issue? Thanks.
