Trying to unlock my new iPhone 12, bought it through ATT, but unable to unlock was able to unlock iPhone 8 with no problem. I did this because I couldn't understand what I was doing wrong. I did not plan on leaving. Called the service after being on hold for 30 min, I drove to the local ATT store. They refused to help me sighting the only reason I unlocking it was to move it over the ATT network. They said they were there to bring in new business, not send it away. Well, guess what, I'm out of here, along with my internet, I have always had problem with ATT service.
