So on the AT&T next plan, you’re supposed to return your old phone after you get a new one. Last year, I didn’t return my 6 Plus and was simply billed the remaining amount on it’s contract. Since I was able to sell it for more, I made a slight profit. I was planning to do the same this year, but I just received an unusual text message from AT&T. After hoping I was enjoying my new iPhone, it reminded me to return the old one, a 7 Plus, or be changed what appears to be the full cost of my 256GB iPhone X! This is appalling. I wonder if the new contact specified this was the case? If so, it’s a hostile move on their part, as financially they were not loosing anything in the way the process worked past year. In fact, I could have paid off the amount of the 7 Plus prior to ordering the new phone, if I had know this was the case. Has anyone got any more details as to what’s happening?
