Your teams keep their phone number, work contacts & more.

We’ll transfer your team’s numbers and show them how to keep their information. 

Check your phone’s compatibility

Every phone has a unique 15-digit IMEI that identifies the make and model, and indicates whether it's ready to use on our network. Most phones are compatible.

To determine network and SIM compatibility, we need your device's IMEI number. Dial *#06# to find the IMEI or

find it in phone settings.
Please enter your 15-digit IMEI number.

FAQ about bringing your own device to T-Mobile:

Bringing your phone to T-Mobile is typically the fastest, easiest, and most economical way to join T-Mobile. To bring your own phone, first check if your phone is compatible with the T-Mobile network. Not all phones have the same network hardware, and it may not work well with T-Mobile's network. If your phone is not compatible, we recommend purchasing a new phone from T-Mobile. Second, your phone must be unlocked to switch to T-Mobile. If your phone is locked, you must contact your current carrier and request it be unlocked.

After checking if your phone is compatible, follow these steps:

  1. Purchase a T-Mobile SIM Card and a T-Mobile Plan.
  2. Replace the existing SIM card in your phone with the new T-Mobile SIM Card.
  3. Optional: Request to transfer your phone number to T-Mobile after installing new SIM card.

If you have questions, please call us at 1-877-590-4728, or visit your nearest T-Mobile store.

Most phone numbers can be transferred to T-Mobile, but please check the transfer eligibility of your existing number. After you have installed your new T-Mobile SIM, contact us via 1-877-590-4728, or visit a store, to complete the transfer process. When you contact us, you will need to share the following information with us to complete the transfer request.

  • Previous Carrier Name
  • Previous Carrier Account Number
  • Account Pin Number
  • Phone Number to be Ported In
We recommend backing up your contacts, voicemail, and text messages prior to transferring your number to T-Mobile. During the process, you may have dual service for up to 24 hours, meaning you will be active on both carrier networks. Do not cancel your previous wireless service until you receive a confirmation text message from T-Mobile that the transfer is complete.
