I bought a used iPhone 14 Pro and my purchase verified at a local AT&T store. It took me many hours online and at the AT&T store to get my phone working with AT&T. And, it was an AT&T locked phone. Very frustrating. Now, after a year of horrible reception, I would like to have my phone unlocked. I have called tech support or six times and spent literally three or four hours on the phone. Each time they say it will be unlocked within three days. Now, nearly 3 weeks later my phone is still . I guess I will either sell the phone or try again. For the life of me, I cannot understand how horrible the tech support people are AT&T.
