So my brother found this Samsung galaxy J5 at the place where he works, waited a month, nobody showed up to pick it up so he took it home. He threw away the sim card and gave it to me. I tried putting my sim card in and starting it up but it asks for
a network unlock code which i don't have, so i tried factory resetting it. That didn't work so i reinstalled the whole firmware, that also didn't work so now i'm at a point where i can maybe look up the network provider key online, but every time i go on a site it tells me to give them a phone number which i don't have. Is their a way of looking up which network my phone is locked to without having it's original sim card and phone number?
