A friend of mine gave me a iphone 5c without a sim card that he told was unlocked. It was already unlocked and i used it well until now without a simcard. I forgot my password after changing it and it locked me out completely (iphone disabled connect to itunes). I reset it and now it requires me to put in a sim card. I borrowed my moms bell sim card from her iphone 6 and it tells its not the same carrier. I check to see what carrier the phone is using copytrans contacts and it tells N/A. If it worked before he gave me it without a sim card, why is it not working now? I can't seem to find the carrier if its even still locked with a carrier. I want to see if there a solution before I spend money to unlock the phone.
