I see on the website that my iPhone 6 is compatible for BYOD. When I went to the store to switch, the rep said that you can only BYOD iPhone 7 & up from ATT. Which is true. Also, I tried to trade in and the rep said they won’t do trade ins from ATT. Please advise if the website is correct or the xfinity store rep is. I have another iPhone 6 that I would like to switch from ATT but I would prefer to BYOD.
