I recently bought a used Surface Duo.
I was careless in choosing and i picked an AT&T Duo which is locked.
I live outside USA so i have only non-AT&T sim.

Is there a way to unlock it?

Thanks to whoever can give me help

Go to the ATT unlock site and provide your imei to receive an unlock code. If your imei isn't recognized, call the helpdesk and pound on them for an unlock code. Once you receive it, put your new simcard in the device and click on the unlock message that appears. It's a bit weird where to fill in the code. Provide the unlock code and you are good to go.
