My mother's iphone 8 was broken. She wanted a new i-phone. Since the old one was dead, she could not use the t-mobile app. The clerk said that she needed the app from the old phone or pay cash for the new one. They could not take a credit card. Who carries $600 in cash on them? He said we could try online, and on a display phone had her put her t-mobile user name and password in. How secure is that??? Unfortunately, the site required 2 factored authorization from the dead phone. So, that did not work. I have never seen a more incompetent cell phone place. She could not buy the phone. We had to go to Best Buy, get the phone and come back to have them activate it. I advised her to get a better carrier. read more
