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.
