Discarding Your Old Phone? One Mistake Could Expose Your Personal Data

Many people replace their smartphones within a year, either because they want a newer model or because their existing device is damaged. In recent times, individuals offering cash or plastic goods in exchange for old mobile phones have been visiting residential areas and making announcements through microphones. Police have cautioned the public against trusting such buyers without verification, warning that some old phones collected in this manner could potentially reach cybercrime networks. According to the warning, devices may be repaired, fitted with SIM cards and misused for cyber fraud. Phones that still contain personal information can pose an even greater risk, as photographs, videos, contacts and financial details could potentially be accessed and misused.

Experts and police advise users to take precautions before disposing of an old phone. The SIM card should be removed, important data should be securely backed up and the device should be properly reset after ensuring that accounts and personal information have been removed. If a phone is sold to an individual or dealer, buyers should be properly identified and their address and identification details recorded where appropriate. Sellers should also obtain a receipt mentioning the phone’s IMEI number, date of sale and buyer details. Since the IMEI number can be used during investigations to trace a device, maintaining proof of sale can help establish when and to whom the phone was transferred if it is later connected to a crime.
