I just ordered new service with T-mobile, the 20.5 mobile internet plan, and sim card kit. The agent asked me if I had a old 4g lte hotspot device to use, I did, then told me to contact ATT to get it unlocked. After an exhaustive afternoon on the phone with both carriers, and scouring the internet, it seems nobody can give any firm info on this whether I can actually use this device or not.
My device does have a Micro SIM, but ATT TS isnt sure if it can be unlocked, and so submitted a ticket, and when visiting thier "/device unlock" page and entering the IMEI it leads me to believe it cannot be unlocked, but gives no reasons why, even though I meet all its requirements for unlocking.
Anybody else in this position?
