How to Check a Second-Hand iPhone Before Buying: 16-Point Checklist (2026)

A new iPhone 17 now starts at around ₹99,900 in India after Apple's September 2026 price revision, up from ₹82,900 at launch. The new iPhone 18 Pro starts at ₹1,64,900. No wonder so many people are switching to a second-hand iPhone instead. As we wrote recently, used phone demand in India is growing fast.

The used market has its traps, though: stolen phones, iCloud-locked units, cheap replacement screens and batteries that are quietly on their last legs. This guide is the checklist we'd want a friend to use. It's a shorter version of what our technicians run on every phone before it goes on sale, and it takes about 20 minutes.

Save it, screenshot it, and take it with you when you go to see the phone.

Before you meet the seller: 3 checks from home

1. Check if the phone is stolen (KYM / Sanchar Saathi)

Ask the seller for the phone's 15-digit IMEI number. Any genuine seller will share it. Then SMS KYM <space> IMEI to 14422. For example: KYM 123456789012345.

You'll get a reply with the phone's status. If it says blacklisted, duplicate or already in use, walk away. You can run the same check on the government's Sanchar Saathi portal or app. Dual-SIM iPhones have two IMEIs, so check both. Our Sanchar Saathi guide explains how the system works.

2. Check the serial number on Apple's website

Ask for the serial number and enter it at checkcoverage.apple.com. It shows the exact model, whether the purchase date has been validated, and whether any Apple warranty or AppleCare+ is left. If the model it shows doesn't match what's in the ad, stop there.

3. Ask for the bill and the box

An original invoice is the best proof the phone isn't stolen, and you'll need it for any warranty claim. "Bill is lost" is common. "No bill, no box, and the price is very low" is a pattern you should take seriously.

The 16-point checklist: when the iPhone is in your hand

Identity and ownership

1. IMEI matches everywhere. Dial *#06#, then compare that IMEI with Settings > General > About, the SIM tray (it's printed on the tray of many models), the box and the bill. They should all match. A mismatch usually means the board or body has been swapped.

2. Model number. In Settings > General > About, look at Model Number (tap it to switch between the two formats). The first letter tells you where the phone came from:

M: sold new at retail
F: refurbished (by Apple or a carrier)
N: a replacement unit Apple gave out during a repair
P: a personalised (engraved) phone

None of these is a deal-breaker. An "F" just means the price should reflect that it's a refurbished unit. To check if an iPhone is Indian, look at the end of the model number: Indian units end in HN/A.

3. iCloud / Activation Lock is removed. This is the big one. Ask the seller to sign out of their Apple ID (Settings > [their name] > Sign Out) and then erase the phone in front of you: Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. When it restarts, you should see the "Hello" setup screen and be able to set it up with your own Apple ID.

If it asks for the previous owner's Apple ID or password, that's Activation Lock. Don't buy it. There's no legitimate "iCloud bypass", whatever a seller promises.

One 2026 gotcha: if the seller has Stolen Device Protection turned on and you're meeting away from their home or office, iOS may make them wait an hour before Find My can be switched off. Meet at their place or wait it out. Never accept "I'll remove the account later."

4. No carrier lock. In Settings > General > About, Carrier Lock should say No SIM restrictions. Then put your own Jio, Airtel or Vi SIM in, make a call and open a website on mobile data.

5. SIM tray or eSIM only? US-model iPhones from the iPhone 14 onwards have no physical SIM tray. They're eSIM only. Indian-model iPhones still have a SIM tray, except the iPhone Air, which is eSIM only everywhere. An imported eSIM-only phone isn't illegal, but make sure you're okay with it and that the price reflects it.

Battery and hidden repairs

6. Battery health and cycle count. Go to Settings > Battery > Battery Health. 85% or above is good for an older iPhone, and 80–84% is okay if the price reflects it. On iPhone 15 and newer, also check the cycle count. Our iPhone battery health guide explains every percentage in detail.

7. Parts and Service History. Still in Settings > General > About, scroll down. If the phone has ever been repaired, you'll see a Parts and Service History section listing the battery, display, camera or other parts, each marked Genuine Apple Part or Unknown Part. An unknown display or battery is a reason to negotiate hard, or to leave.

Screen and Face ID

8. Display. Open a plain white page, then a dark grey image, and tilt the phone under good light. Look for:

dead or stuck pixels
yellow or pink patches
green or pink vertical lines (a known issue on some OLED screens)
burn-in (faint ghost images of the keyboard or status bar)

Drag an app icon slowly across the whole screen to make sure touch works everywhere. Finally, long-press the brightness slider in Control Centre. If the True Tone button is missing, the screen has most likely been replaced with a non-original one.

9. Face ID or Touch ID. Go to Settings > Face ID & Passcode and set up a new face (or fingerprint on the SE). If you see "Face ID is not available", don't buy it. That repair is expensive and often can't be done properly outside Apple.

Cameras, sound and network

10. Every camera. Switch between every lens (0.5x, 1x, 2x/3x/5x and the front camera). Take photos and a short video in each. Watch for blurry focus, black spots or a lens that won't switch, and listen for a buzzing or rattling sound. That's a stabilisation fault. Check the flash and torch too.

11. Speakers and microphones. Record a voice memo and play it back. Play a video at full volume. Make a call on both the earpiece and speakerphone, and ask the other person whether they can hear you clearly.

12. Network and connectivity. Test calls, mobile data, Wi-Fi and Bluetooth (pair your earbuds), then open Maps and check that the GPS finds you quickly.

Body, ports and the small stuff

13. Charging. Plug in a cable and make sure it starts charging straight away and the cable sits firmly. If you have a MagSafe or wireless charger, test that too.

14. Buttons and haptics. Press volume up and down, the side button, the mute switch or Action Button, and Camera Control on iPhone 16 and 17 models. Turn on vibration and feel for a crisp buzz, not a rattle.

15. Body condition. Check the frame for dents and the back glass for cracks. Back glass is expensive to replace on many models. Look for gaps between the screen and the frame. A lifting screen can mean a swollen battery or a phone that's been opened carelessly.

16. Water damage, storage and software. Shine a torch into the SIM tray slot. The small liquid contact indicator inside turns red if the phone has met water. Then confirm the storage in Settings > General > About > Capacity matches the ad, and check Settings > General > Software Update to make sure it can update.

Red flags: walk away if you see these

The price is far below the market rate. Our second-hand iPhone price guide shows what's normal.
The seller won't share the IMEI or refuses to erase the phone in front of you.
Anyone offering an "iCloud bypass" or "only iCloud locked, works fine".
A request for an advance UPI payment before you've seen the phone, or a "courier-only" deal with a stranger.
"Unknown Part" on the display or battery when the seller told you it was never repaired.
No bill, no box, and a story that keeps changing.

Buying from a person vs buying from a store

	Individual seller (OLX, Facebook, friends)	Certified store like The Digital Hub
Price	Usually the lowest	A little higher, for checks and warranty
Warranty	None	Minimum 3 months, some phones 6 or 12 months
Returns	None	7-day returns
IMEI and iCloud check	You do it yourself	IMEI-verified and iCloud-clean before listing
Battery health	Whatever the seller tells you	Shown on every iPhone listing
Bill	Maybe the original one	GST invoice with the IMEI on it
EMI	No	3, 6, 9 or 12 months on cards

Buying from an individual can absolutely work if you follow every step above. If you'd rather not do all of this yourself, that's exactly what a good store is for.

Frequently asked questions

Is it safe to buy a second-hand iPhone in India?

Yes, as long as you check the IMEI status (KYM to 14422), make sure the seller removes iCloud and erases the phone in front of you, and test the hardware. Buying from a store that offers a warranty and returns removes most of the risk.

How do I know if an iPhone is refurbished?

Check the first letter of the model number in Settings > General > About. "F" means refurbished. Also check Parts and Service History for replaced parts.

How can I check if an iPhone is Indian or imported?

Look at the model number in Settings > General > About. Indian iPhones end in HN/A. US models from the iPhone 14 onwards also have no SIM tray.

Can iCloud lock be removed?

Only the original owner, or Apple with proof of purchase, can remove Activation Lock. Anyone selling an "iCloud bypass" is selling a phone you won't be able to use properly. Don't buy it.

How do I check a second-hand iPhone's battery health?

Go to Settings > Battery > Battery Health. 85% or more is good for an older iPhone. See our full battery health guide for what each percentage means.

Which second-hand iPhone should I buy?

For most people in 2026, the iPhone 13 is the best value and the iPhone 15 Pro is the cheapest iPhone that runs Apple Intelligence. Our 2026 buying guide covers every budget.
