Reselling Used iPhones in Europe
A buying checklist and a pricing method for second-hand iPhones.

- Walk away from any iPhone that shows "iPhone Locked to Owner" or asks for someone else's Apple Account after an erase: Activation Lock is designed to stop anyone else using the phone.
- Read three screens before you pay: Settings > General > About (serial, carrier lock, parts history) and Settings > Battery > Battery Health, then put what they show in your own listing.
- Price from phones of the same model, storage and battery band, and measure the battery discount from your own comps; no marketplace publishes it.
- In Poland, OLX gives private users 2 free smartphone listings and business users 0, while Allegro Lokalnie takes 4.9% on Elektronika Kup teraz and auction sales and 0 zł on local listings (checked 13 September 2026).
- A Swappie quote, lockable for 14 days, is a floor to compare with your net at a quick-sale price.
- Checks before you pay: IMEI, Activation Lock, carrier lock
- Battery health, replaced parts and water damage
- What sets the price: model, storage, condition, colour
- Finding comparable listings
- Where to sell: OLX, Allegro Lokalnie, Vinted, buyback services
- Fees and listing limits for phones
- Shipping and return risk for phones
- Pricing a phone to sell within a week
To resell used iPhones without losing money, check ownership, battery and parts before you pay, price from phones of the same model, storage and battery condition, and pick the channel after fees and listing limits. In Poland, OLX gives private users 2 free smartphone listings, Allegro Lokalnie takes 4.9% on Elektronika buy-now sales, and a Swappie buyback quote gives you a floor.
Apple and marketplace facts below were checked on 13 September 2026. Every other number is an example.
Checks before you pay: IMEI, Activation Lock, carrier lock
Do these in order. The first failure ends the deal.
- 1Match the numbersSerial on screen vs box barcode
- 2Activation LockNo "iPhone Locked to Owner" screen
- 3Carrier lock"No SIM restrictions"
- 4Battery HealthCapacity and any service message
- 5Parts historyGenuine, Unknown or Used
- 6Test itCalls, cameras, charging, Face ID or Touch ID
Numbers. Apple shows the serial and IMEI in Settings > General > About and on the original box barcode; iPhone 6s to 13 also carry the IMEI on the SIM tray. iPhone 14 and later have no IMEI engraving, so compare screen and box.
Activation Lock. On iOS 15 and later a locked phone shows "iPhone Locked to Owner". If setup asks for the previous owner's account, Apple says to hand the phone back for their password, or they can remove it from their account in a browser. It's ready at the Hello screen. The official pages used here offer no public stolen-phone IMEI lookup, so a matching IMEI is only a consistency check.
Carrier lock. "No SIM restrictions" next to Carrier Lock in Settings > General > About means unlocked. Apple says only the carrier can remove a lock.
Decision rule: if the seller won't erase the phone in front of you or show the About screen on a video call, don't buy. How to ask is in spotting fake and risky listings; the scorecard with a phone add-on is in how to evaluate a resale deal.
Battery health, replaced parts and water damage
Settings > Battery > Battery Health shows maximum capacity against the battery when new. Apple designs iPhone 14 and earlier batteries to keep 80% capacity at 500 complete cycles, iPhone 15 models at 1,000. On iOS 15.2 and later, Parts and Service History sits in Settings > General > About; the parts listed depend on the model.
| The phone shows | Apple's meaning | Your move |
|---|---|---|
| "Your battery's health is significantly degraded" | A new battery would restore performance | Compare only with phones showing the same |
| "Unable to verify this iPhone has a genuine Apple battery" | Battery details may be inaccurate | Ignore the capacity figure; disclose it |
| Part marked Unknown or Used | Non-genuine, faulty, or from another iPhone | Disclose; compare only with repaired phones |
We haven't verified Apple's liquid-damage guidance, so there is no water test here. Decision rule: if the seller says the phone got wet, value it as a parts phone unless everything works in your hands.
Vinted UK counts "functionality not as described" and undisclosed damage as not-as-described, but not disclosed wear on electronics; OLX's Pakiet Ochronny also covers function. Grading is in how condition changes resale price.
What sets the price: model, storage, condition, colour
A comparable phone matches yours on every line:
- Same model, not the Pro, Plus or mini beside it
- Same storage
- Same battery band (bands you set and write down)
- Same parts and carrier-lock status
- Similar cosmetic grade, judged from photos
- Same completeness: box, cable, receipt
We found no published data on how much colour moves an iPhone's price, so use it as a tie-breaker.
Finding comparable listings
Search by model and storage, open every listing, and sort phones into battery bands. Note the last price of phones that disappear and the asks of those still listed. The resale pricing guide explains why exits beat asks.
Where to sell: OLX, Allegro Lokalnie, Vinted, buyback services
| OLX.pl | Allegro Lokalnie | Vinted (PL) | Swappie | |
|---|---|---|---|---|
| Seller fee | None within free limit | 4.9% Kup teraz and auctions; 0 zł local | No seller commission | None: you accept a quote |
| Free phone listings | Private 2, business 0 | Free to list | Not stated | Not a listing |
| Business accounts | Can sell; limit 0 | Can buy, not sell | Pro not open to Polish businesses | Not stated |
| Buyer-side charge | Pakiet Ochronny, amount not published | Not stated | Usually 5% + 2.90 zł | Not applicable |
| Buyer check or claim | Claim within 48h | Non-delivery claim after 14 days | Electronics Verification, 20 zł | Inspection up to 3 business days |
Decision rules:
- First or second phone in an OLX limit period, local buyer: OLX with collection; test together at handover.
- Third phone, private user: Allegro Lokalnie. OLX renews a limit 30 days after the last counted listing was published (OLX listing limits by category).
- Distant buyer wanting reassurance: Vinted, where the buyer can add Electronics Verification; but standard accounts are personal, so regular flipping doesn't fit.
- You want a number now: a Swappie quote. On its trade-in route, if Swappie revises the price, you can accept or get the phone back free.
The same choice over four routes, peer marketplaces against refurb buy-out, trade-in and breakers, is worked through in where to sell used phones.
Vinted's updated Terms take effect on 8 October 2026 in Poland and the UK (5 October in Germany and France); press reports say the Buyer Protection fee becomes the "Vinted fee". Recheck the price list then.
Fees and listing limits for phones
Worked example: a phone sold for 1,500 zł.
- Allegro Lokalnie Kup teraz: 4.9% is 73.50 zł, leaving 1,426.50 zł before shipping. It's charged only if the buyer pays within 72 hours or fills in the delivery form. A secondary source reports 4% for electronics; Allegro's page showed 4.9%, so check the form.
- Vinted: no seller commission, but at the usual 5% + 2.90 zł the buyer sees about 1,577.90 zł before shipping.
- OLX: free inside your limit; paid prices aren't in the documents we read.
Shipping and return risk for phones
On OLX delivery the buyer has 48 hours from pickup or delivery to claim, and you have 120 hours to respond. An accepted claim means a return at your cost and a refund of price, delivery and Pakiet Ochronny fee; change of mind isn't covered. Details: OLX delivery and Pakiet Ochronny.
- State battery capacity, any battery or parts message, and carrier-lock status
- Film the phone working and being packed
- Follow Apple's steps: sign out of your Apple Account, Erase All Content and Settings, remove it from trusted devices, erase any eSIM
Pricing a phone to sell within a week
No marketplace publishes how fast phones sell, so a week is a target. Price near the cheapest quarter of comparable asks. An Allegro Lokalnie auction runs 7 days, a built-in deadline.
Worked example: fast sell is around 1,350 zł. The 4.9% Kup teraz fee is 66.15 zł, leaving 1,283.85 zł. A Swappie quote of, say, 1,250 zł is 33.85 zł less, with no messages or claim window. Decision rule: if the gap is worth less than that work, take the quote; otherwise list at fast sell. Laptops and consoles, where OLX also sets a private limit of 2, are in reselling used electronics.
