How to unlock your iPhone to use it with another carrier

Major cellular carriers — Verizon, AT&T, T-Mobile, Sprint, and others — typically lock their networks to the iPhone you buy from their stores or pay for via an installment plan. What does that really mean, though? A cell phone lock is a software code that ensures your mobile phone connects only to a specific network. Conversely, unlocking your iPhone means that you can switch carriers if you’re dissatisfied with the service, move to a different region, are traveling, or want to keep your old handset when you change networks.

To switch carriers, you must rely on your current carrier to unlock your phone. While Apple can’t unlock your iPhone, its support page lists the carriers that offer unlocking services, such as AT&T, Boost Mobile, Sprint, T-Mobile, Verizon, Virgin Mobile, Xfinity, and many more.

Unlocking your iPhone requires you to meet certain criteria. For example, your phone must be paid in full, by completing an installment plan or coming to the end of any other contract you signed. The handset cannot be reported lost or stolen, and your account must be in good standing. If you paid for your iPhone in full upon purchase, then it’s probably unlocked already. Unlocked iPhones are generally worth more than locked mobile devices. It’s generally a good idea to unlock your phone when it goes off-contract. If you’re ready to unlock your iPhone, here’s how to do it.

Contacting your carrier

Verify that your carrier offers unlocking. Note that it might take a few days to complete the process after you submit your request.

• Contact your carrier and request an unlock.
• Wait for your carrier to confirm that your iPhone is unlocked.
• If you have a SIM card from a different carrier, remove it and insert the new one.
• Set up your iPhone again.
• If you don’t have another SIM card, back up your iPhone.
• After the backup, erase your iPhone.
• Restore your iPhone from the backup you made.

Error message? Here’s what to do

You might see this message on your computer or on your iPhone: “The SIM card inserted in this iPhone does not appear to be supported. Only compatible SIM cards from a supported carrier may be used to activate iPhone. Please insert the SIM card that came with your iPhone or visit a supported carrier store.” If you see that message, do this:

• Since iOS 14, you should check your phone’s status. Go to Settings, General, and select About. Look for the section called Carrier Lock. This section should say No SIM Restrictions. If you don’t see that message, then your carrier probably hasn’t unlocked your phone yet. Contact your carrier immediately to find out what is going on.
• This should be enough to get your iPhone properly unlocked, but if you keep having difficulties, you may have to restore your iPhone to factory settings and reboot from a backup.

Unlocking an AT&T iPhone

Start the process here.

If you have AT&T, you can use the convenient device unlock portal to avoid customer service phone contact. This process could take a few days, and you will receive a confirmation once it’s completed. To disengage your iPhone from the AT&T network, you must first do the following.

• If you are on a current contract or an installment program, pay off the balance, including any termination fees.
• If you’ve paid off your balance early, wait at least 24 hours after payment.
• Make sure your phone has not been reported lost or stolen, that it hasn’t been involved in fraud, and that the account is in good standing.
• Your phone must have been active for at least 60 days, with no past due or unpaid balance. It also cannot be active on a different AT&T customer’s account.
• If you upgraded early, you must wait for the 14-day “buyer’s remorse” period (30 days for business customers) before unlocking your old phone.
• Military members can unlock iPhones, including those on installment plans, but make sure to register your active-duty status when filling out AT&T’s forms.
• When ready, provide AT&T with your EMEI number on the unlock page (dial *#06# to find it).

Double-check whether the unlock has been completed by consulting AT&T’s online Unlock Status Page, or wait for the confirmation email. If the unlock has gone through, remove your AT&T SIM card and insert the SIM for your new carrier to begin the setup process. Don’t worry about iPads and wearable devices with LTE connections. Those are handled separately from smartphones and are sold unlocked.

Unlock a Verizon iPhone

Start the process here.

Both prepaid and post-paid iPhones you purchase from Verizon are locked for 60 days after purchase, then will be automatically unlocked.

• Devices purchases from Verizon retail partners are locked for 60 days after activation, not purchase.
• Prepaid and Postpay devices both follow the same 60-day rule.
• If you are deployed as a member of the military, contact Verizon directly to unlock by request.

Devices that you purchase from Verizon’s retail partners are locked for 60 days after activation. After 60 days, Verizon automatically removes the lock. That means that if you have fulfilled all financial obligations and your phone is otherwise clean, you can remove the Verizon SIM card and insert a different one of your choosing. Customers who are in the U.S. military and stationed outside of the Verizon coverage area can get their iPhones unlocked on request even during the 60-day lock period.

Unlock a T-Mobile iPhone

Start the process here.

T-Mobile has a number of terms and conditions you must meet before it will unlock your iPhone from the network.

• Your account must be in good standing, and your phone must not be reported lost, stolen, or blocked to T-Mobile.
• You have requested no more than two mobile device unlock codes per service line in the last 12 months.
• If the device was financed using T‑Mobile’s Equipment Installment Plan (EIP), then all payments must be made and the device must be paid in full unless otherwise specified.
• For post-paid accounts, your phone must be active on the T‑Mobile network for at least 40 days. If the device is on a canceled account, the balance must be paid in full.
• If the device is on an account with a service contract term, then at least 18 consecutive monthly payments must have been made. Or, the account must have been migrated to a no-contract rate plan.
• Prepaid iPhones must have been active on the T‑Mobile network for more than one year. If active for less than a year, the prepaid account must have more than $100 in refills since the first use date.
• T‑Mobile may request proof of purchase or additional information at its discretion, and certain other exceptions may apply.
• As with other carriers, exceptions for military personnel, business, and government accounts may apply under certain circumstances.

T-Mobile should send unlock notifications to your phone once it is eligible, and may send you an unlock code you will need to enter. If you don’t have this information, contact T-Mobile directly and ask for it. You will then need to look in your phone settings for the Permanent Unlock option, this can vary a bit between manufacturers, but the link we provided above has more information. Contact T‑Mobile Customer Service for details.

Unlock a Sprint iPhone

Sprint no longer exists. After its merger with T-Mobile, the carrier is no longer an entity. However, this presents a problem, as T-Mobile will only unlock iPhones purchased directly from T-Mobile, not Sprint. If you have a Sprint iPhone that is still locked, your best bet is to call Customer Care numbers and explain your situation:

• Post-paid customers: 888-211-4727
• Previous Sprint Forward customers: 855-639-4644

Unlock a UScellular iPhone

Start the process here.

iPhone models 7 through 12 and the SE2 are locked into the UScellular network for 120 days after activation to prevent fraud and theft. For locked 4G LTE devices launched before February 1, 2016, some can be unlocked via a software update. UScellular-locked 1X and 3G devices launched before February 1, 2016, can be unlocked with a request to customer service.

After the 120-day lock period ends, UScellular automatically unlocks the aforementioned iPhone models if your account is in good standing. During the 120-day lock period, the carrier will unlock your post-paid device on request if you are on military duty with deployment overseas. Your post-paid account must be in good standing or paid in full, and you must have otherwise met all financial obligations.

Third-party lock breakers

If you encounter problems with an official carrier unlock, you can still opt for an IMEI unlock, which works identically to the official carrier unlock. There are plenty of IMEI unlock companies, but it’s best to go with trusted vendors like Express Unlocks, DoctorSIM, MobileUnlocked, UnlockBase, Cellphone Unlock, UnlockUnit, Unlock River, and Unlock Radar. Check review sites like Trustpilot before making a final decision or paying up. The price to unlock an iPhone varies based on your carrier. Lock breaker services support models from the newest iPhone 11 series all the way back to the iPhone 4.

Most third-party unlocking services operate the same way. From their website, you pay varying amounts, usually under $100, for an email-based unlock code. Most require upfront payment. Reputable unlocking services have customer support lines and deliver codes quickly.

Buy an unlocked iPhone

Every iPhone you buy from Apple — either online or from an Apple Store — is unlocked, except for specific carrier financing options. An unlocked iPhone lets you choose any carrier you want. To get started with a new carrier, do the following:

• Switch off your iPhone.
• Remove the current SIM card from your old carrier.
• Insert the new SIM card for your new carrier.
• Restart your phone.
• Upon restart, follow the on-screen instructions to set up your phone.

You can also buy a SIM-free iPhone, which means your iPhone does not come with a carrier SIM card, which frees you to use a SIM card from any compatible carrier. Of course, you will have to pay for your new phone upfront and in full.

If you can’t pay in full, you might consider Apple’s iPhone Upgrade Program, where you get an unlocked iPhone in much the same manner as the SIM-free option. Not only do you avoid the upfront cost, but you also get to pay in monthly installments and are eligible for an upgrade after 12 payments. The program includes the AppleCare+ protection program alongside a $4.17 per month add-on for AppleCare+ with Theft and Loss protection. The upgrade plan does require a credit check.
