Securely Dispose of Your Old Phone and Avoid Buying a New One with These Tips.
When getting rid of an old cellphone, it's important to securely wipe all data to prevent it from falling into the wrong hands. This can be done by transferring data directly to a new device or backing up the old device via iCloud or iTunes. To securely get rid of data on an iPhone, unpair devices, sign out of iCloud, iTunes, and the App Store, and reset the device. For Android and Samsung devices, go to Settings, select System, then Advanced, and under Reset options, select Erase all data. Instead of throwing away old cellphones, consider selling, recycling, or donating them through various programs.
