    Did you purchase an unlocked iPhone or an iPhone that is carrier locked with O2?

    Assuming it is an unlocked phone try the following...

     

    Try a hard reset, the equivalent of a PC/Mac reboot.  No data will be lost on the phone.

     

    Press and hold the Power and Home buttons simultaneously for at least 6 seconds or until you see the Apple logo and then release.  The phone will then reset... may take up to a minute to complete.
