Transferring your phone number details
A number transfer (also known as porting, port-in, or WLNP) allows you to bring your existing phone number from another provider over to T-Mobile. This can be done as part of a new activation, or to replace an existing T-Mobile phone number.
To be transferred, your number must be a working number and must meet other eligibility criteria. See if you're eligible for transferring your phone number to T-Mobile.
Initiating a transfer request
To initiate your number transfer request, simply let us know you have a number you want to bring to T-Mobile. This is normally done as part of your activation either in a T-Mobile store, online at T-Mobile.com, or by phone at 1-800-TMOBILE.
Only the number is transferred, not the phone or service
Your phone number is the only thing brought over from your old provider to T-Mobile. Your calling plan, coverage, service, features, and equipment will all be obtained through T-Mobile and do not need to be the same as what you had previously.
Transferring from T-Mobile to another provider
T-Mobile cannot initiate a request to transfer an existing T-Mobile number to another provider, also known as a port-out. A port-out happens only in response to a port-in request being submitted with a new service provider. Find out about transferring your T-Mobile number to another provider.
How do I transfer my phone number?
These steps explain the process of transferring your phone number to T-Mobile:
- Start with a working telephone number you want to bring to T-Mobile.
- Check to make sure your number is eligible to transfer. See if you're eligible for transferring your phone number to T-Mobile.
- Activate service with T-Mobile either in store, online at T-Mobile.com, or by phone at 1-800-TMOBILE. Tell us you want to transfer your existing phone number.
- We initiate the number transfer request for you.
- Your current service provider responds to the request. The response may be:
- Permission to transfer the number
- A delay, meaning the current service provider needs extra time to respond to the port request
- A request to fix missing or mismatched information on the request

- The old service provider gives T-Mobile permission to transfer the number.
- T-Mobile notifies the network that we are transferring the number.
- T-Mobile moves the number over and sends a text message to your new handset.
