Hi. So someone recently gave me an iphone 5 as they got a new phone. i wiped the phone and was unable to bypass the setup screen as you need a simcard. so i found an old nano sim put it in and it said the sim was invalid. i tried a friends Sim aswell and the same thing happened. I checked to see if the phone was unlocked via https://www.icloud.com/activationlock/, and activation lock is off. So why cant i activate the phone with any sim?
