Unlock request approved, but phone is still locked to AT&T
I am not an AT&T customer, but I received a Samsung S8 Plus from my brother that was used on AT&T. I have been going around in circles trying get it unlocked so I can use it on Boost for about 3 months. Boost tells me the phone should work on their network once it's unlocked. My brother has requested the phone be unlocked at least 3 times, and i have done it twice. Every time, it is approved, and we are sent the same unlock code. But there's nowhere to enter it. With a Boost sim card in the phone, it starts up with the AT&T logo and apps and wants me to set up an AT&T account.
I've called a store and been told I need to wait for a third email AFTER the "unlock approved" email for it to work. I've gone to a store and been told there was nothing they could do but request it to be unlocked again. I spent an hour and a half on the phone with a rep who eventually said my brother should just request another unlock because mine wasn't associated with the original account, or something to that effect. I called again tonight and a rep straight up said, "Nothing we can do, sorry." I can't understand how the company the phone is locked to is either unable or unwilling to help.
I know for a fact that the phone is paid off. Every time i receive an unlock approved email, there are no instructions. It just says this:
