i bought an iphone 3GS that was on O2, had it unlocked so i can use my orange sim card, when i insert it everything is fine, but throughout the day (after texting,using the web etc) it will say the network is restricted and my signal wont come back no matter where i am, the only way i can get the signal back is to take the sim card out, put it in my old phone and then put it back in th eiphone, then it will work for a few hours/minutes and then go back to restricted, i checked its not stolen as if the IMEI was blocked i wouldnt be able to text, make calls etc
anyone got any ideas what the problem could be ?
