Answer to: iPhone 5 won't activate after factory resetGot the same issue here. My phone has been searching for signal for almost 5 days!!! I also tried everything: - restart the phone several times -hard reset - network settings reset - take out the sim card then insert it back (I also tried to insert my sim on a different phone and it's working fine!) - lastly, factory reset And now, I'm stuck on activation phase because got an error "Could Not Activate iPhone because activation server is temporarily unavailable. Try connecting to iTunes or try again in a few minutes." It won't let me use my phone again. Smh!
