Most major US carriers will unlock your phone for free in 2026, and many will do it automatically once you meet the requirements. The catch is that the rules changed at the start of this year, every carrier handles it differently, and a lot of the paid “IMEI unlock” services online will charge you for something that should cost nothing.
This guide walks the legitimate path for AT&T, T-Mobile, and Verizon. It also covers what to do if you bought the phone secondhand, how to skip the unlock process entirely, and the cases where no amount of IMEI magic will help.
We run Swift Tech Buy. We see carrier-locked phones every day in our buyback and repair queues, and we resell hundreds of unlocked refurbished phones a year. The unlock dance is one of the most common questions our customers ask, and one of the easiest places for a person to get scammed.
This guide is the same answer we give in person, with the steps written out.
The IMEI is a 15-digit number that uniquely identifies your phone. Carriers and manufacturers use it to track devices across networks. Every cellular phone has one. Dual-SIM phones have two.
You’ll need your IMEI for almost any unlock conversation with a carrier, so step one is finding it.

Track Order *#06# on the keypad. The IMEI shows on screen instantly.Write it down or screenshot it. You’ll paste it into a carrier portal in a few minutes.
Half the bad advice on phone unlocking comes from articles that mix up three different processes. Before you do anything, figure out which one applies to you.
Carrier unlock (network lock). Your phone works fine, but it only accepts SIM cards from one carrier. You drop in a different carrier’s SIM and see “SIM not supported” or a network lock icon. This is what most people mean by “unlock,” and it’s what this guide handles.
iCloud / Activation Lock. You turn on the phone and Apple asks for an Apple ID and password that you don’t have. This is owner-side security on iPhones, and only the original Apple ID holder can clear it. No IMEI service can fix this legitimately.
Blacklist / bad ESN removal. The phone won’t activate at all because it was reported lost, stolen, or has an unpaid balance attached to it. This isn’t a lock you remove with a code. We covered this in detail in our bad ESN guide — short version, only the carrier or the original reporter can lift it.
If you’re past those three and you’re sure you want a carrier unlock, keep reading.
The exact rules changed in early 2026, and they’re different for postpaid (monthly bill) vs prepaid (pay up front) plans. Here’s where each major US carrier stands today.
Postpaid requirements:
How to unlock: Many eligible AT&T iPhones now unlock automatically, no request needed. Check by going to Settings, General, About, and looking at the “Carrier Lock” line. If it says “No SIM restrictions,” you’re done.
If it still shows locked, submit a request at att.com/deviceunlock. You’ll need the IMEI. AT&T usually processes manual requests within 24 to 48 hours.
For prepaid (Cricket, AT&T Prepaid), the wait is 6 months of paid service.
Postpaid requirements:
How to unlock: T-Mobile auto-unlocks eligible devices within 2 business days once they meet the criteria. You usually don’t need to submit anything.
To check status, open the T-Mobile app, go to Account, then Manage Lines. If your device shows “Eligible to unlock” or “Unlocked,” you’re good. You can also check on iPhone at Settings, General, About, Carrier Lock.
For prepaid (Metro by T-Mobile, T-Mobile Prepaid), the wait is 365 days of paid active service.
This is the carrier that changed dramatically in January 2026.
Postpaid requirements (devices activated on or after January 13, 2026):
Postpaid requirements (devices activated before January 13, 2026):
The old 60-day auto-unlock rule still applies. Your phone unlocks automatically 60 days after activation if it isn’t flagged for fraud.
How to unlock: For devices on the old rule, the unlock happens automatically at the 60-day mark. For devices on the new rule, the unlock happens once your device payment plan is fully paid off, with the possible 35-day waiting period after.
To check or request, dial *611 from your Verizon phone, or call 888-294-6804.
For prepaid (Verizon Prepaid, Total by Verizon), the wait is 365 days of paid active service.
If you bought a used phone and it’s locked to a carrier you don’t use, things get harder. Carriers generally only unlock devices for the original account holder.
You have three options:
If the phone has an unpaid balance from the original owner and they won’t pay it, the phone is effectively bricked from a carrier-unlock standpoint. That’s a bad ESN situation, and our bad ESN guide covers what you can actually do with one.
Don’t pay for an unlock if you don’t need one. Two quick checks:
iPhone: Settings, then General, then About. Look at the “Carrier Lock” line. If it says “No SIM restrictions,” your iPhone is unlocked. Done.
Android: Try a SIM card from a different carrier. Power off, swap the SIM, power back on. If the phone connects and shows full bars on the new carrier, it’s unlocked. If you see “SIM not supported” or a network lock prompt, it’s still locked.
If you bought your phone directly from Apple, Samsung, or Google at full retail price, it’s almost always unlocked from day one.
This used to be a popular trick: buy a locked phone from one of the big three carriers, then activate it on a budget MVNO (like Mint Mobile or Cricket) that runs on the same network. No unlock needed.
That stopped working in 2025. All three major carriers now use IMEI-level blocking to keep locked phones off their partner MVNOs, even when it’s the same physical network underneath.
If you see a guide telling you this trick still works, the guide is out of date.
Now for the part most articles skip.
A lot of the “unlock with IMEI” content online sells the idea that the IMEI is a magic key that opens any phone. It isn’t. There are situations where no legitimate path exists, and pushing through paid services makes things worse, not better.
You still owe money on the phone.
Every major US carrier requires the device to be fully paid off before unlocking. Pay it down or wait it out. There’s no shortcut, and any service claiming to bypass this is selling you smoke.
The phone is reported lost or stolen.
A blacklisted phone is not a candidate for unlocking. Even if some service “removes” the carrier lock, the IMEI is still in the GSMA blacklist and the phone won’t activate on any major US carrier. See our bad ESN guide for what you can actually do with one.
Third-party “IMEI unlock” services. Most of them are scams.
Carrier unlocks from AT&T, T-Mobile, and Verizon are free if you meet the requirements. Anyone charging you to unlock a phone you already qualify to unlock is selling you something you can get for nothing. Worse, some of these services install software that bricks the phone, harvest credentials, or claim to “remove” a blacklist (which they can’t). If your phone is eligible, the carrier will do it free. If it isn’t, no third-party service can fix that legitimately.
The phone is locked, financed, and the original owner has stopped paying.
This is a stuck situation. The carrier won’t unlock until the balance is paid, and you’re not the one who can pay it. The phone is effectively trapped.
In our stores, about 1 in 10 “unlock my phone” requests we see falls into one of these buckets. Telling someone the truth saves them $50 in scam fees and a lot of wasted time.
If you’re looking at all of this and thinking “I just want a phone that works on whatever carrier I pick,” there’s a simpler option: buy a phone that’s already unlocked.
Phones bought directly from Apple, Samsung, or Google at full retail price are unlocked out of the box. So are most certified refurbished phones from independent resellers, including ours.
At Swift Tech Buy, every refurbished phone we sell is verified unlocked, with a clean IMEI checked against the GSMA database, and backed by a warranty. You skip the entire unlock dance, you don’t have to worry about a financed-phone surprise from the previous owner, and you save 30 to 50 percent versus new.
Yes. Unlocking your own phone has been legal in the US since 2014, when Congress passed the Unlocking Consumer Choice and Wireless Competition Act. The catch is that the carrier sets the eligibility rules, and you’re still on the hook for any installment balance.
A legitimate carrier unlock does not void your manufacturer warranty. Apple, Samsung, and Google all honor warranties on carrier-unlocked phones. What can void warranty is jailbreaking (iOS) or rooting (Android), which are different from carrier unlocking. Don’t confuse the two.
No. Every major US carrier requires the device to be paid off in full before unlocking. Postpaid installment plans, leases, and upgrade programs all count. You can pay the balance off early and request the unlock, but you can’t skip the payoff.
Carrier unlock removes the network restriction so the phone accepts other carriers’ SIM cards. The phone software is otherwise unchanged. Jailbreaking (on iPhone) or rooting (on Android) modifies the operating system to remove Apple or Google restrictions on what apps can run. Carrier unlock is legal, free, and warranty-safe. Jailbreaking is legal but voids the warranty.
No. Phones reported lost or stolen are blacklisted, and a blacklisted phone is blocked from activating on any major US network regardless of unlock status. Anyone selling you an “unlock service” for a stolen phone is committing or facilitating a crime.
Once your phone is carrier-unlocked, you can use any compatible international SIM or eSIM. There’s no separate “international unlock.” If you’re traveling soon and your phone hasn’t met the unlock criteria yet, deployed military personnel can request an early unlock with documentation. Otherwise, plan ahead, or buy an unlocked travel phone.
No. Carrier locks and IMEI-level blocks live below the user-resettable layer. A factory reset wipes your apps and settings. It does not remove the carrier lock.
T-Mobile: typically 2 business days, automatic. AT&T: 24 to 48 hours after submitting a request, often automatic for iPhone. Verizon: automatic at the eligibility moment for older devices, or after payoff (with a possible 35-day delay) for devices on the new January 2026 policy.
In 2026, the legitimate path to unlocking your phone is simple: pay off the device, keep your account in good standing, and let the auto-unlock kick in or submit a free request through the carrier’s portal. Skip the paid services. They’re usually scams, sometimes destructive, and never necessary for a legitimate carrier unlock.
If you bought the phone secondhand or you’re stuck in one of the unlock-impossible cases (blacklisted phone, financed phone with an unreachable original owner, stolen device), buying a verified unlocked refurbished phone is the cleaner path forward. We sell those at Swift Tech Buy, all carrier-unlocked from inventory, with clean IMEIs and a warranty.
If your phone has a different problem on top of the unlock question, like a cracked screen, a dead battery, or a SIM reader issue, our repair team can diagnose it for free at our Chicago and Milwaukee stores. Most repairs are same-day. We’ll also tell you straight if a phone isn’t worth fixing, and what your trade-in value would be toward something newer that’s already unlocked. Either way, you walk out with a working phone.
We accept phones that are re-financed or not paid off as long as they are not blacklisted.
