Hi everyone, I traded in my iPhone 6 to AT&T last year for their "free" iPhone 7 program. I know if I upgrade my phone through AT&T Next I will loose those monthly credits (trying for that not to happen). I am giving my fiance my iPhone 7 and upgrading to the the iPhone X. If I use the iPhone Upgrade Plan, will this set off a red flag on AT&T's servers when I have to verify I am a customer at checkout? Or will my monthly credits be safe as long as I finance through Apple and not AT&T. TIA!
