Your checklist

Titles only

Work through the list in order. Hide the notes when you know what to do.

Make a backup and verify it
Check that the backup exists and opens, not merely that the setting is on. After the reset it is too late to check.

An unverified backup is the most common way photos are lost: the setting is on but nothing has uploaded for months.
Move your data to the new phone and check it
Photos, contacts, chats, notes, passwords. Use the new phone for a few days before selling the old one.
Move two-factor authentication
Authenticator apps and confirmation codes. This is the step that costs people access to their accounts after a sale.
Unlink payment methods and transit cards
Cards in the wallet, device-linked subscriptions, passes. Do it before the reset, not after.
Sign out of every account
Email, cloud, messengers, banking, social media, streaming. In the browser too, not only in apps.
Unlink the phone from the manufacturer account
This step is mandatory: otherwise the device stays locked to you and the buyer cannot use it.

A forgotten account link is the most common cause of a returned phone and the most unpleasant for both sides.
Remove the SIM and memory card
These are forgotten inside more often than anything else. Check the tray even if you are sure.
Test cameras, sound, buttons and charging
Both cameras, speakers, microphone, vibration, sensors, Wi-Fi and the port. The buyer will test this — better to know first.
Check the battery health
It is the buyer's first question. An honest figure saves both sides time and reduces haggling.
Clean the body, port and speakers
Carefully, with no liquid in the openings. A clean phone looks better and sells faster.
Gather the box, cable and paperwork
Completeness noticeably affects the price. A receipt and warranty card, if you kept them, help too.
Photograph the phone honestly, in daylight
From every side, including chips and scratches. Honest photos filter out people who arrive to argue about condition.
Perform a full reset once everything else is done
Only in this order. A reset before unlinking leaves the phone locked to you.
Check real prices for the same model
Compare listings with the same condition and storage, not the price of a new one. You avoid underselling and month-long waits.
Arrange a safe meeting
A busy place in daylight. Let them test it, but do not leave your SIM inside and do not follow anyone into a stairwell.
Wait for the money to actually arrive
A screenshot of a transfer means nothing. Never read out a code from an SMS — that is always a scam, whatever the story.
Remove the device from your accounts after the sale
Revoke sessions, check the device list in your email and cloud, confirm codes arrive on the new phone.

Selling a phone is about data first and price second

A phone remembers more than a laptop: messages, photos, payment details, access to your bank and email, where you have been. So preparing to sell is not “reset it” but a sequence: back up, unlink accounts, reset — and only then advertise.

Order matters. Resetting before you unlink the account leaves the device tied to you: the buyer cannot use it, and you get an unpleasant conversation and a refund.

The right order

Step	Why this way
Back up	After a reset there is nothing left to restore
Transfer to the new phone	Verify everything actually moved
Sign out of accounts	Email, cloud, messengers, banking, streaming
Unlink from the manufacturer account	Otherwise the phone stays locked to you
Remove the SIM and memory card	They are routinely forgotten inside
Full reset	Only after all of the above

What to check before advertising

Completeness of the box, the condition of the body and screen, cameras, speakers, microphone, buttons, charging and Wi-Fi. Check the battery health: buyers ask about it first, and an honest answer saves everyone time.

Photograph the phone in daylight from every side, including chips and scratches. Honest photos reduce haggling and filter out people who come to argue.

Doing the sale safely

Meet in a busy place, ideally during the day. Let the buyer test the phone, but do not hand it over with your SIM card inside. If they pay by transfer, wait for the money to actually arrive rather than accepting a screenshot. And remember: any request to “send me the code from the SMS” is a scam, whatever the explanation.

After the sale

Remove the device from your account device lists, revoke its sessions, check that two-factor authentication has moved to the new phone, and unlink payment methods. This is the step people forget and then remember when a login alert arrives.

When the phone is ready to sell

The backup is made and verified, data has moved, accounts are unlinked, SIM and memory card are out, the reset is done, the device is removed from your accounts, the box is assembled and the honest photos are ready.

Frequently asked questions

What should I do before selling my phone?

Make and verify a backup, move your data and two-factor authentication to the new phone, sign out of all accounts, unlink the device from the manufacturer account, remove the SIM and memory card — and only then perform a full reset.
