What unlocking means and why AT&T does it

Unlocking your AT&T phone means removing the software restriction that ties it to AT&T's network. Once unlocked, your phone can connect to any carrier's SIM card — domestic or international — instead of only AT&T. AT&T will unlock phones that meet their requirements, but the process takes time and has specific conditions you need to meet first.

AT&T locks phones to protect against theft and to may support customers complete their service contracts. If you own your phone outright, have paid it off, or meet other conditions AT&T sets, they will remove that lock. The unlock itself is permanent — once done, it stays done even if you switch back to AT&T later.

You cannot unlock a phone yourself through settings or third-party software without voiding your warranty and potentially breaking the phone. AT&T controls the unlock through their system, and you request it from them.

Key Takeaways

  • AT&T will unlock your phone only if it is paid off, not reported stolen, and has been active on their network for a set period (usually 60 days for postpaid accounts).
  • You can request an unlock through AT&T's website, by calling 611 from your AT&T phone, or by visiting an AT&T store in person.
  • The unlock process takes up to 24 hours after AT&T approves your request, though most complete within a few hours.
  • Once unlocked, you will need a SIM card from your new carrier to use the phone on their network.
  • AT&T does not charge a fee to unlock phones that meet their requirements.

Check whether your phone meets AT&T's unlock requirements

Before you request an unlock, confirm your phone qualifies. AT&T has four main requirements: the phone must be paid off (no remaining balance on a device payment plan), it must not be reported as lost or stolen, it must have been active on AT&T's network for at least 60 days (for postpaid accounts), and it must not be subject to an active service contract that ties it to AT&T.

If your phone is still on a payment plan, you can pay off the remaining balance when ready and then request the unlock. If you are unsure whether your phone is paid off, log into your AT&T account online or call 611 from your AT&T phone to check your device balance. The representative can tell you the exact amount owed and whether you can pay it over the phone.

Prepaid AT&T phones have different rules. If you use AT&T prepaid service, your phone becomes may be able to access for unlock after you have actively used it for 12 months and recharged it at least once every 30 days during that period. Check your prepaid account status online or ask at an AT&T store to confirm you meet the prepaid unlock timeline.

Request your unlock through AT&T's website

The fastest way to request an unlock is through AT&T's online unlock portal. Go to att.com/deviceunlock and sign in with your AT&T account credentials. You will need your phone number, account PIN (the four-digit code you set up for account security), and your device's IMEI number.

To find your IMEI, dial *#06# on your AT&T phone and a 15-digit number will appear on your screen. Write it down or take a screenshot. Enter this number into the unlock form on AT&T's website along with your account information. AT&T will verify that your phone meets their requirements and send you a confirmation email if the request is approved.

Once approved, AT&T sends an unlock code or initiates an over-the-air unlock, depending on your phone model. Most modern phones receive the unlock automatically without any action on your part. Older phones may receive a code via email that you enter into your phone's settings. Check your email (including spam folders) for AT&T's unlock confirmation within a few hours of submitting your request.

Request your unlock by phone or in person

If you prefer to speak with someone, call 611 from your AT&T phone or call 1-800-331-0500 from any phone. Tell the representative you want to unlock your device. They will verify your account information, confirm your phone meets the unlock requirements, and submit the request on your behalf. This call usually takes 5 to 10 minutes.

You can also visit an AT&T store in person with your phone and a photo ID. The store representative will check your account, verify the phone is paid off and may be able to access, and submit the unlock request while you wait. In-store requests sometimes process faster because the representative can confirm your identity when ready and resolve any account issues on the spot.

Whether you call or visit a store, ask the representative for a confirmation number or reference ID for your unlock request. Write it down. If you do not receive your unlock confirmation email within 24 hours, you can use this number to check the status of your request.

What happens after AT&T approves your unlock

After AT&T approves your unlock request, the actual unlock process begins. For most modern phones (iPhone 6 and newer, Samsung Galaxy S5 and newer, and most phones made in the last five years), AT&T sends the unlock over the air — meaning your phone receives it automatically without you doing anything. This usually happens within a few hours but can take up to 24 hours.

You do not need to restart your phone or change any settings. The unlock happens in the background. To confirm your phone is unlocked, power it off completely, then power it back on. If you see no AT&T logo during startup or if your phone no longer shows "AT&T" in the status bar, the unlock is complete.

For older phones, AT&T may email you an unlock code instead. If you receive a code, follow the instructions in the email exactly. Usually you will go to your phone's settings, find the "Unlock" or "Network Unlock" option, and enter the code. Do not share this code with anyone — it is specific to your phone and account.

Use your unlocked phone on a different carrier

Once your phone is unlocked, you can use it with any carrier that supports your phone's hardware. You will need a SIM card from your new carrier. If you are switching to a different carrier, contact them to order a SIM card or pick one up at a retail store. Some carriers (like T-Mobile and Verizon) can set up service on your phone when ready if you have an existing account with them.

Insert the new carrier's SIM card into your phone, power it on, and follow the carrier's set up instructions. Your phone will connect to the new carrier's network within a few minutes. You may need to update your phone's network settings — the new carrier will provide these details when you set up service.

Keep in mind that unlocking your phone does not transfer your service, phone number, or account to the new carrier. You are responsible for setting up a new account with the new carrier and porting your phone number if you want to keep it. AT&T's unlock only removes the network restriction from the phone itself.

Troubleshooting if your unlock request is denied

If AT&T denies your unlock request, the most common reason is that your phone still has a balance owed. Check your account balance again and pay off any remaining amount. Once the balance is zero, wait 24 hours and submit a new unlock request. AT&T's system sometimes takes time to update after a payment is processed.

Another common reason for denial is that your phone has not been active on AT&T's network for the required 60 days (or 12 months for prepaid). If this is the case, you will need to wait until the time requirement is met. AT&T will tell you the exact date your phone becomes may be able to access in their denial message.

If your phone is reported as lost or stolen, AT&T will not unlock it. Contact AT&T when ready to clear this status if it was reported in error. If your phone was actually stolen and you have recovered it, you will need to provide proof to AT&T before they will remove the theft flag and process your unlock.
