If you do not want to migrate your current number, go back to T-Mobile Connect and select Sign Up you can cancel your existing account later if you want.


Migrate your account to T-Mobile Connect Prepaid

This process is for existing T-Mobile postpaid customers who want to migrate to a new T-Mobile Connect Prepaid account, or for existing customers who do not have the option to change their plan to T-Mobile Connect when logging in to My T-Mobile.

What you will need to get started

Before you can migrate your account to T-Mobile Connect you will need the items below.

  • A new SIM Card ($10), your current T-Mobile SIM card will not work with T-Mobile Connect Prepaid. Don't worry, you can keep your existing mobile number. If you have more than one T-Mobile number you want to migrate to T-Mobile Connect, contact us by dialing 611 from your T-Mobile phone.
  • The mobile number from your existing account you want to migrate.
  • Existing T-Mobile account number.
  • PIN/Passcode from your existing T-Mobile account (different from your My T-Mobile password - it's the one you use when you call us).
  • An email address different from the one associated with your existing T-Mobile account.

What you need to know

  • Some services and benefits are unavailable for T-Mobile Connect, such as device protection, Netflix On Us, T-Mobile app self-service, and Team of Experts support.
  • Any existing service promotions, such as free lines or monthly discounts, will be lost and may not be available if you decide to convert back in the future.
  • When you migrate your account any existing outstanding service or device payment balance on your postpaid account will immediately become due.
  • Your voicemail account will be reset and you will lose any voicemails not saved to your device.
  • Your account tenure will reset, which may affect your ability to qualify for some device pricing programs in the near future.
  • You need to keep your account active until you activate your new SIM card. 
  • Once your new SIM card is activated it will take 2 to 4 hours to transfer your existing mobile number to your new SIM card.
