Transfer your phone number to T-Mobile

Switch to T-Mobile, and keep the number you already have.

It's easy to transfer your number(s)

If your phone number(s) are eligible for transfer to T-Mobile, you can transfer them in one of two ways:

  1. Dial 611 from the phone you're activating, or call Customer Care at 1-877-453-1304, when you receive your new T-Mobile phone or SIM card (we recommend this method if you need to use your current phone until your new T-Mobile phone or SIM card arrives).
    OR
  2. Follow the number transfer instructions on the payment page at checkout (we recommend this method if you do not need to use you current phone until your new T-Mobile phone or SIM card arrives). For information on shipping times, see our shipping options.

Reminder: Do NOT cancel your wireless account until your T-Mobile account has been activated.

FAQs

If I switch, will T-Mobile pay my Early Termination Fees?

Individuals and families (up to 10 lines) who are currently under a postpaid contract at carriers including AT&T, Sprint or Verizon and want to switch to T-Mobile can take advantage of the Early Termination Fee (ETF) reimbursement offer. Follow the steps below:


  1. Transfer your number(s), trade in your phone(s) and tablet(s) and receive a bill credit based on the market value for your eligible device.
  2. Then, when you get your final bill listing your Early Termination Fee (ETF) amounts, you simply send it to T-Mobile or submit it online at switch2tmobile.com, and if you qualify, within 8 weeks you will receive a Visa® Prepaid card covering your ETF amount up to $350 per line. The card is not redeemable for cash and expires in 12 months unless extended by Issuer. Learn more >

How do I transfer my number so I can get the ETF?

Your number must be eligible to transfer. You have the option of transferring your number to T-Mobile at checkout, or waiting until you receive your new phone in the mail.


If transferring at checkout, we recommend selecting overnight shipping to avoid any delay in service.


If you wait until your new device arrives, dial 611 from your T-Mobile phone or call Customer Care at 1-877-453-1304 to complete the number transfer immediately after receiving the new device.


Can I switch to T-Mobile but keep the phone number I already have from another carrier? How would that work?

Yes, it is possible to keep the number you already have from another wireless or landline carrier. First, check to see if your existing number is eligible for transfer to T-Mobile. If it is, then all you have to do is follow the on-screen instructions displayed during check out to authorize the transfer. We'll do the rest. In rare circumstances we are unable to transfer a number to our network. This is often because we don't have a transfer agreement with the original service provider.


Be sure to keep your old phone and old account until your number is fully activated on your new account for seamless service. You should also consider using the overnight shipping option to ensure that your new phone arrives before service on your old phone stops.
