Thinking about switching to T-Mobile and wanting to keep your number?

You can keep the number you already have from another wireless or landline carrier. Transferring your number, also known as porting, is the process by which you transfer your phone number from one carrier to another. In rare circ*mstances, 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.

• There is no charge for transferring your phone numbers.
• Wireless line: the transfer will typically complete from 10 minutes to 3 hours.
• Landline: the transfer may take anywhere from 3–10 days.The timing of your number transfer depends on the accuracy of the information provided.
• If your phone is not active with your new phone number after you have waited the expected time, contact T-Mobile Customer Careat 1-800-T-Mobile. Sometimes we need to validate or modify information, such as misspelled names, addresses, etc. before we can complete the transfer.
