Selling your phone is a smart way to unlock value from a device you no longer need, but it is also a moment where data security really matters. Phones store far more personal information than many people realise, from photos and messages to banking details, passwords and work accounts.
The quick verdict
Before selling any phone, take control of your own data rather than relying only on the buyer. Back everything up first, sign out of iCloud or remove your Google account, and remove payment and banking apps. Specialist platforms such as Envirofone securely wipe every device, but preparing it yourself protects your information and helps avoid delays or reduced valuations.

Whether you plan to sell your iPhone, trade in a Samsung device or send in a wearable, these data security tips will help ensure your information stays safe.

For iPhone users, backing up to iCloud or a computer ensures everything can be restored on your next device. Android users can use Google backup or manufacturer specific tools.
Backing up first removes the fear of losing data and allows you to reset your phone with confidence.
Sign Out of Accounts Properly
One of the most common mistakes people make is forgetting to sign out of accounts before resetting their phone.
