A friend gave me an iPhone 4 after he bought an iPhone 5 and everything works except the parts that need a SIM card. I put a SIM card in from my old phone but there is no signal, in the top left corner of the iPhone 4 it says “No Service”. Do I need to register the SIM card to the iPhone somehow? And if so do I need to get a new SIM card from a network that Apple has approved? I live in the UK, do I need to be on O2?


Thanks for any help!

iPhone 4, iOS 6.0.1
