An old handset sitting in a drawer loses value every month, and most people either forget about it or hand it over without wiping it properly. You can sell your old phone safely, get a fair price, and be confident that nothing of yours travels with it. The whole process takes under an hour spread across two days.
Do the data steps before you do anything else
The order matters. Wiping first and then remembering you needed a photo is a bad afternoon.
Back up everything. On Android use Google One backup plus Google Photos; on iPhone use an iCloud backup or a computer backup. Verify the backup completed and shows today’s date rather than assuming it did.
Move your authenticator codes. This is the step people forget, and it is the one that locks you out of accounts. Transfer two-factor codes to the new phone before wiping, using the app’s export or transfer function.
Sign out of your accounts. Remove the Google account on Android and sign out of iCloud on iPhone. This is what disables the activation lock. A phone still tied to your account is unusable to a buyer and will get returned.
Remove the SIM and any memory card. Obvious, and still one of the most common mistakes.
Then factory reset. Modern phones encrypt storage by default, so a factory reset genuinely destroys the keys and makes the old data unrecoverable. Do it from Settings, not by deleting apps manually.
Get more money for the handset
Condition drives price more than age. A three-year-old phone with an unmarked screen often beats a two-year-old one with a cracked corner. Clean it properly with a slightly damp microfibre cloth, clear the dust out of the charging port with a wooden toothpick, and replace a cheap case rather than including a battered one.
Then check several prices, not one. Trade-in programmes from carriers and manufacturers are convenient but usually pay the least. Specialist buyback sites pay more. Selling directly to a person pays the most and takes the most effort. Get quotes from all three before deciding, and remember to include the original box and cable if you still have them, which typically adds a small but real premium.
Timing helps too. Prices for older models drop sharply in the weeks after a new flagship launches, so selling before that announcement is worth a little planning.
How to sell your old phone safely to a private buyer
Direct sales pay best and carry the most risk, so a few rules make it straightforward. Meet in a busy public place during daylight, ideally inside a bank or a police station car park with cameras. Accept cash or an instant bank transfer you can see confirmed in your own app before handing anything over. Be wary of any buyer who wants to pay by a method with easy reversal, or who invents an urgent reason to complete the sale differently from what you agreed.
Write down the IMEI before the sale, found by dialling star hash zero six hash. If a dispute ever arises, that number identifies the exact device. Take a few photos of the phone powered on and working on the day of the sale as your own record.
If it is not worth selling
Some phones are too old or too damaged to be worth listing. Do not bin them. Batteries in landfill are a genuine hazard, and the metals inside are recoverable. Manufacturer takeback schemes, network operator drop-off points, and municipal e-waste collections all accept old handsets free. Charities also refurbish working phones for people who need one.
The EPA has guidance on electronics donation and recycling, and the FTC covers what to do before handing on a mobile device.

A simple two-day plan
Day one: back up, move your authenticator, get three price quotes. Day two: sign out of your accounts, remove the SIM, factory reset, clean the handset, and complete the sale. Follow that order and you will sell your old phone safely, at a better price than a rushed trade-in, without leaving a single photo, message or login behind on a device that is no longer yours.
