Do not use AT&T or their online trade-in service. I traded in an iPhone 11 and they are claiming they received an iPhone 8 so I am not getting any money for my trade (costing me over $800). There is no oversight of their "back office" that processes trade-ins and there is no way for customers to verify what was sent in. They told me I cannot use Find My iPhone to locate my phone or have my trade-in phone returned to me. They told me there is nothing I can do that their "back office" has made their decision and I am out of luck. Have been a customer of AT&T for 20 years and will be switching to Verizon and I recommend everyone else does as well.
