What about your phone number?
Transfer your existing number
Ready to join us? Review how to Switch your numbers to T-Mobile. To switch your lines to T-Mobile, you’ll need to have the following information from your current carrier:
- Phone numbers
- Account number (often located on your bill or online account)
- Account PIN (often used to verify your account)
- Personal accounts may require a Number Transfer PIN
- Some carriers offer ‘porting protection’ which restricts carrier transfers. Contact your carrier for information on this service and how to remove any restrictions.
