Unlock problem: The "Enter the device unlock code" screen does not appear on reboot
I have obtained from AT&T an unlock code for the AT&T-locked Samsung S22 I bought privately. Unfortunately, when I reboot with the Consumer Cellular SIM card, I do not receive the screen that allows me to enter the unlock code. Could it be because Consumer Cellular (as an MVNO) uses AT&T on this particular SIM card?
Thanks for any advice.
