An investigation commissioned by data protection company CPP Group found that many people in the UK who sell their old smartphones and SIM cards are failing to wipe the devices of sensitive personal data. More than half of the devices examined for the study were found to contain credit card PINs, bank account information, and login information for social networking sites. The information was gathered from 35 used phones and 50 used SIM cards. Users selling old phones should perform a factory reset. Unless old SIM cards are being transferred to another of the owner's devices, they should be destroyed.
