How do I unlock on a prepaid device
I need to unlock a prepaid AT&T device, but I'm not a costumer (I was gifted the phone). I submitted a unlock request online, but it was rejected because I have to use the unlock app on the device since it's prepaid. The device was recently factory reset and since then the unlock app crashes seconds after opening each time. I desperately need to unlock this phone, soon. Is there anything I can do?
