Who buys carrier-locked iPhones, and what are they worth?
Short answer: Wholesale and export-facing buyers buy carrier-locked iPhones. A locked iPhone is a fully working, legally sellable phone — it just only accepts SIMs from one carrier, which shrinks the pool of people who can resell it. Consumer buyback sites that sell one unit at a time to a US shopper often refuse locked stock or discount it hard. Buyers who move volume into channels where that carrier's network is the dominant one can pay much closer to unlocked money.
Before you get a quote, work out which of four completely different things you actually have: carrier locked, financed, blacklisted, or iCloud (activation) locked. People use the word "locked" for all four. Two of them are sellable, one is sellable only after you clear the balance, and one is not sellable at all.
The four things people call "locked"
This table is the single most useful thing on this page. Most bad advice about selling iPhones comes from mixing these up.
| State | What it actually means | Does the phone work? | Can you legitimately sell it? |
|---|---|---|---|
| Carrier locked ("SIM locked", "network locked") | The phone only accepts SIMs from one carrier — AT&T, Verizon, T-Mobile, Metro and so on. A software restriction set by the carrier, usually because the phone was subsidised or financed. | Yes, fully — on that carrier | Yes. Worth less than unlocked, but a normal sale. |
| Financed ("still on a payment plan", "on installments") | You still owe money on the device under an instalment agreement. This is a financial status, not a technical one — it is not stored on the phone. | Yes | Not until the balance is zero. The lender has a claim on the device until you pay it off. |
| Blacklisted ("bad ESN", "blocked IMEI") | The IMEI has been reported lost or stolen (or, sometimes, flagged for an unpaid balance) and entered in the GSMA global registry. Networks refuse it. | Wi-Fi only — no cellular service on any US carrier | No. Reputable buyers and marketplaces reject these outright. |
| iCloud / activation locked | Find My is still on and the phone is still tied to someone's Apple Account. Turns on automatically the moment Find My is enabled. | Not until the original Apple Account password is entered | Parts value only, and only where the seller is the verified owner. Fixable in two minutes if it's your own account. |
Note what the table implies: a carrier-locked, fully paid-off iPhone with a clean IMEI is an ordinary used phone with an ordinary used-phone value. The panic people feel about the word "locked" mostly belongs to the other three rows.
Why locked iPhones are worth less — the actual mechanism
The honest explanation is about who can bid, not about the phone. An unlocked iPhone can be sold to literally anyone on earth with a compatible network. An AT&T-locked iPhone can only be sold to someone who has an outlet for AT&T-locked phones. Fewer possible bidders means a lower clearing price. That is the entire mechanism.
It follows that the size of the discount is not a fixed percentage — it depends on the buyer:
- A retail-facing buyback site resells to a single US consumer who wants a phone that works on any carrier. A locked unit is close to useless to them, so they either refuse it or price it defensively. This is where you see the ugliest numbers.
- A wholesale distributor with export channels can aggregate locked units into lots and move them into markets or specialist channels where the lock isn't a defect. The discount is real but far smaller.
- A private buyer on Marketplace almost always wants unlocked, and will discover the lock and renegotiate at the meet-up.
We are not going to give you a universal percentage, because there is no credible public dataset behind any of the percentages you'll find quoted online. Estimates in the trade press tend to land in the low double digits for recent iPhones, but that is an estimate, not a measurement, and it varies enormously by model, carrier and month. Get a firm number on your specific model instead.
Two secondary effects are worth knowing. First, the gap is widest on current flagships, where unlocked demand is strongest, and narrows on older models. Second, a phone that is locked but unlock-eligible — paid off, past the carrier's waiting period, clean IMEI — is worth more than one that isn't, because a buyer can reasonably expect to get it unlocked.
Who actually buys carrier-locked iPhones
| Buyer type | Takes locked iPhones? | What to expect |
|---|---|---|
| Consumer mail-in buyback sites | Sometimes, heavily penalised | Many quote you an unlocked price, then re-grade on arrival once they see the lock. Read the revised-offer policy before shipping. |
| Carrier trade-in programs | Usually yes | Store credit or bill credit, typically spread over 24-36 months of billing, and normally only if the device is paid off. |
| ecoATM-style kiosks | Yes | Fast and low. Automated grading is at its most conservative exactly on non-standard inventory. |
| Peer-to-peer (Swappa, Marketplace) | Yes, if the IMEI is clean | Swappa checks every IMEI against the GSMA registry and blocks anything reported lost or stolen. Locked-but-clean is listable, at a discount. |
| Wholesale / export buyers | Yes — this is their inventory | Best prices on locked stock, and the only ones who reliably take mixed lots and multiple units at once. |
How to check what you've actually got — in about three minutes
- Lock status. Settings → General → About → Carrier Lock. "No SIM restrictions" means unlocked. Anything else means locked.
- IMEI. Dial
*#06#, or Settings → General → About. Write it down; every check below uses it. - Lost/stolen status. Run the IMEI through stolenphonechecker.org, the free CTIA service built on GSMA's Device Check. A clean result means the IMEI has not been reported.
- Financing balance. Your carrier account or app shows the remaining instalment balance on each line. Zero means you own it.
- Activation Lock. Settings → your name → Find My → Find My iPhone. If it's on, turn it off and erase the device before handing it over. If it stays on, nobody can set the phone up.
"Apple can't unlock your iPhone for use with a different carrier. Only your current carrier can unlock your iPhone." — Apple Support, "How to unlock your iPhone for use with a different carrier"
That sentence rules out an entire category of scams. Anyone offering to "factory unlock" your iPhone for a fee outside of your carrier's own process is, at best, selling you something they can't reliably deliver.
Should you unlock it before selling?
If you qualify, usually yes — an unlocked phone sells to a bigger audience for more money, and the carrier does it for free. Whether you qualify depends on the carrier: AT&T requires the device to have been purchased more than 60 days ago with a zero instalment balance; T-Mobile postpaid requires 40 days of active service on the requesting line and the device paid in full; Verizon postpaid unlocks once the financing balance is cleared. Prepaid is much stricter across the board — typically a full year.
If you don't qualify — you're two weeks in, or you left the carrier years ago and can't get the account reopened — that is not a dead end. It just means you should be selling to a buyer who prices locked inventory properly rather than one who treats it as a defect. Our guide to selling an AT&T-locked iPhone has the exact requirement for each carrier.
What we buy, and what we don't
Fusion Upgrade LLC has been buying and reselling devices from Rochester, New York since 2018, currently rated 4.9 out of 5 across 174 Google reviews. We buy carrier-locked iPhones — AT&T, Verizon, T-Mobile and others — alongside sealed, used, cracked, water-damaged and non-working devices, plus Samsung Galaxy, Google Pixel, iPad, MacBook, Apple Watch, AirPods and Beats. We can price locked stock properly because we also operate as a wholesale distributor with export and specialist buyer channels, so locked inventory has somewhere to go.
We are equally clear about what we will not touch:
- Phones with an unpaid instalment or financing balance. You can't sell what you don't yet own. Clear the balance first — see selling a phone that's still on a payment plan.
- Devices reported lost or stolen, or otherwise blacklisted. No offer, no exceptions.
- iCloud / activation-locked devices get a parts-only quote, and only where the seller is the legitimate owner. If it's your own Apple Account, just remove it and get the full price instead.
