How do I bring my phone from Verizon to T-Mobile?

Once your compatible phone is unlocked, purchase a T-Mobile SIM card and choose a T-Mobile plan.
Replace the existing SIM card in your phone with the new T-Mobile SIM card. See video instructions.

How do I check if I can bring my phone to T-Mobile?

Using your own phone with T-Mobile is fast, easy, and economical. If you want to bring your own phone, you’ll first need to check if your phone is compatible with the T-Mobile network and see if it’s unlocked. Some phones have network hardware that may not work well with T-Mobile's network. We want you to have a great experience using our network, so if your phone isn’t compatible, we recommend an upgrade to a new T-Mobile phone. If your phone is locked, contact your current carrier to request unlocking.

What's an IMEI number?

The IMEI (International Mobile Equipment Identity) number is a unique 15-digit number that identifies a specific mobile device. IMEI numbers are issued by the GSM Association, which supports mobile operators and device makers. An IMEI number can be used to determine the device make and model, and whether the device is locked or unlocked. If a device has been lost or stolen, the IMEI can also be used to block it from being used on most carrier networks, including T-Mobile's.

How do I submit for my Virtual Express Prepaid Mastercard?

Sign up for T-Mobile ID and submit for the rebate for each line brought (ported-in) over within 14 days of activation at: https://t-mobile.com/promotions using promo code: 2020SWITCH1. Have your device IMEI ready when submitting for your rebate (dial *#06# to retrieve). Please ensure you accurately enter your IMEI as incorrectly entered IMEI's can lead to your rebate submission being denied.

What's a SIM card?

SIM stands for Subscriber Identity Module. The SIM card is a tiny plastic card with an integrated chip. When you insert it into your device, the SIM card identifies the device to the network. You'll need a T-Mobile SIM card to connect to the T-Mobile network.

Can I bring other devices like tablets, laptops, and hotspots to T-Mobile?

Yes, if your device uses technology that’s compatible with the T-Mobile network. Refer to the device manufacturer’s website for details. If you have questions, take your device to the nearest T-Mobile store and we’ll be happy to help you.

Why do you use the IMEI to check network compatibility?

Using the IMEI is the fastest and most accurate way for us to determine compatibility with T-Mobile's network and check whether a device is locked or unlocked. Many phones appear to work the same way across different carriers, but they can have significant internal differences with their technology and software. By using your device IMEI, we can better understand the device’s capabilities on our network and see if it’s unlocked.

How do I bring my phone from AT&T to T-Mobile?

First, use the IMEI number to check if your AT&T phone is unlocked and compatible with T-Mobile's network.
If your phone is locked, you can request that it be unlocked at the AT&T Device Unlock Portal.
Once your compatible phone is unlocked, purchase a T-Mobile SIM card and choose a T-Mobile plan.
Replace the existing SIM card in your phone with the new T-Mobile SIM card. See video instructions.

If my device is locked, how do I get it unlocked?

If your phone is locked, you’ll have to have it unlocked by the original carrier. In some cases, the phone may have a finance agreement that needs to be paid off before the carrier will unlock it. It may also take a few days to unlock the device.

Can I keep my existing phone number if I bring my own device?

Most phone numbers can be transferred to T-Mobile, but check the transfer eligibility of your existing number before switching to T-Mobile. After you've installed your new T-Mobile SIM, call us at 1-800-937-8997 or visit a T-Mobile store to complete the transfer process. To get started, you'll need the following information:

Previous wireless company name
Previous wireless account number
Previous account PIN
Existing phone number

We recommend backing up your contacts, voicemail, and text messages before transferring your number to T-Mobile. During the process, you may have dual service for up to 24 hours, meaning your device will be active on both carrier networks. Please do not cancel your previous wireless service until you receive a confirmation text message from T-Mobile saying that the number transfer is complete.

How do I bring my phone from Sprint to T-Mobile?

First, use the IMEI number to check if your Sprint phone is unlocked and compatible with T-Mobile's network.
If your phone is locked, you can learn more about unlocking it here: Unlocking your Sprint device
Be sure to read Sprint's device unlocking FAQs as well.
Once your compatible phone is unlocked, purchase a T-Mobile SIM card and choose a T-Mobile plan.
Replace the existing SIM card in your phone with the new T-Mobile SIM Card. See video instructions.

Will the T-Mobile SIM card work in any device?

Yes, the T-Mobile SIM card will fit all GSM phones. The SIM card actually includes adaptors for three different card sizes. When you remove the previous SIM card, you can match it to the correct size T-Mobile SIM. See video instructions on how to replace your SIM.

How do I find out if my phone is unlocked?

Enter your device’s IMEI into the T-Mobile device compatibility checker at the top of the page, and we’ll check to see if we can determine whether it’s locked or unlocked. In most cases, we can tell a phone’s status, but we can’t guarantee we have information for every device. If we’re not able to determine whether your device is locked or unlocked, you may need to contact the previous carrier.
