Used iPhone buying checklist
By the iphonefix.us editorial team · Research-based, last researched 30 October 2026.
Rule one: most used-iPhone disasters are preventable in five minutes, before money changes hands. A phone that looks perfect can still be Activation-Locked, carrier-locked, blacklisted, or financed — and the seller may not be able to fix any of those after you pay.
Before you meet or pay
- Ask for the IMEI/serial number and check it against a stolen-phone checker and the carrier, where available. A seller who refuses to share it is a red flag.
- Ask: is Find My off, and will you remove it from your account in front of me? If the answer is vague, walk away.
- Ask for the original receipt if the phone is recent or expensive. Without it, an Apple Support ownership request later will be very hard.
On the phone, in person
- Activation Lock: the phone should reach the normal home screen with the seller's account signed out, or go through setup without asking for a previous owner's Apple Account. If it asks for someone else's account, do not buy it on a promise.
- Carrier lock: Settings > General > About > Carrier Lock should read “No SIM restrictions” if you need any carrier — or match the carrier you actually use.
- SIM/eSIM test: insert your SIM or activate your eSIM and make a call. A “SIM Not Supported” message means a carrier lock problem, not a setting you can fix.
- Hardware: test Face ID/Touch ID, cameras, speakers, microphone, charging, and buttons. Check battery health in Settings > Battery > Battery Health.
- MDM / supervised: if setup shows a remote-management or organisation screen, the phone may belong to a company or school. Do not buy it for personal use.
Payment rules
- Pay only after the checks above pass, in a traceable way, with a written receipt naming the seller, IMEI, price, and date.
- Never pay extra for an “unlock service” bundled with the sale. If the phone needs unlocking, the seller should unlock it before the sale — see the carrier unlock guide and the Activation Lock guide.
- If a deal is far below market price and the seller is in a hurry, treat urgency as a warning sign, not a bargain.
If you already bought a locked phone, start with the previous owner, then Apple Support with proof of purchase. Do not pay an IMEI site first — see how fake bypass tools work.
Example: the perfect-looking phone
A phone can look flawless, with a clean screen and full battery health, and still be unusable for you. If setup shows an organisation or remote-management screen, it may belong to a company or school. That is not a bargain to negotiate down — it is a phone to walk away from.
Tip: Meet the seller in person and watch the phone complete setup to the home screen with your own SIM and account before you pay. A phone that cannot finish setup is not a bargain.
Frequently asked questions
What is the single most important check before buying used?
Activation Lock. The seller should remove the device from their account in front of you, before you pay.
Should I pay first and check later?
No. Pay only after the lock, carrier, SIM, and hardware checks pass, with a written receipt naming the IMEI.
What if the phone shows a management screen at setup?
Do not buy it for personal use. It may be enrolled by an organisation, and you cannot legitimately remove that enrolment yourself.
