A while back when my brother's phone broke, we decided to use my old iPhone 5 as a temporary replacement for him. I did a factory reset on the phone, and we tried activating it with his SIM card but it wouldn't activate it. A month and a half later, just for the fun of it, I'm trying to activate it again but I can't. I've got my current phone's SIM card installed but for whatever dumb reason the phone says it isn't supported. The phone is locked in with Fido, and this is indeed a Fido SIM card which doesn't make any sense to me. Actually, this is the same SIM card that came out of this iPhone 5 when I got a new phone. The SIM card works fine otherwise. Other SIM cards don't work either. It's not important that we get this phone activated, I'm doing it just for the fun of it. Does anyone have any suggestions for me?
