I left ATT and went with Consumer Cellular(CC). I have a Samsung S8. I requested an unlock code.
CC uses either ATT or T-Mobile towers. I wanted to use ATT towers and inserted my NEW CC SIM card and the phone worked fine. I did NOT have to enter an unlock code.
I am traveling out of the country and received a T-Mobile SIM card from CC. I inserted it and now the phone wants me to enter an unlock code.
I tried to go to att.com/deviceunlock but it would not give me a new code. Telephone support will not help, saying they cannot do anything, I have to request the unlock code.
What do I need to do to get an unlock code?
