Iphone 4, not recognising SIM card, tried other sims and no success. Also tried restoring phone, now I cant restore it as it cant detect the SIM
Basically, phone suddenly said there was no SIM card, despite being able to recieve texts moments earlier. There were no bumps or anything out of the ordinary between these. Tried the recommened tips but no success, also tried restoring my Iphone but now it cant be activated as it cant find the SIM, tried my brothers SIM with no success but my SIM worked in his phone. Does anyone have any suggestions?
iPhone 4, iOS 6.1.3
