For a limited time, new voice customers who switch (bring your number) to T-Mobile from an eligible postpaid carrier (AT&T, Verizon, or another eligible carrier. See complete list at T-Mobile.com/port) can bring their eligible phone and we will reimburse you up to $800 per line on the remaining device payment balance (up to 8 voice lines) via virtual prepaid card (card usually takes 15 days). With Keep and Switch, you can keep your 5G phone, keep your number AND get the 5G experience your phone deserves on America’s largest and fastest 5G network.

Cell phones have unique software and in some cases hardware for each wireless carrier’s network is different and not compatible with one another. We’ve already done the work to check that all phones listed as eligible work great when they’re brought to T-Mobile. We will continue to work with phone manufacturers to enable more devices to easily move between carrier networks and still deliver the awesome experience T-Mobile is known for.

To qualify for T-Mobile to reimburse your remaining device payment balance, up to $800, you must:

• Have a device financing agreement on an eligible device with AT&T, Verizon, or another eligible carrier (see complete list at T-Mobile.com/port), and have had the agreement for at least 90 days on that network.
• Activate a new voice account on a qualified rate plan. All plans currently sold by T-Mobile are eligible with some exclusions.
• Before you bring (port) your number to T-Mobile, ensure your phone is unlocked and ready to go on our network. It’s quick and easy to check your phone’s compatibility here.
  • For customers with phones locked to the carrier (AT&T, Verizon, or another eligible carrier, See complete list at T-Mobile.com/port) you will have to pay off your phone, request unlock from your previous carrier, and wait for your unlock request to be granted (typically takes 1-3 days) prior to bringing (porting) your number over. Bringing (porting) your number to T-Mobile prior to unlocking your phone will result in loss of access to service on the T-Mobile network due to your current incompatible locked phone.
• Download a PDF of your most recent bill that shows your phone’s financing details including the previous carrier’s name & phone number, phone’s make & model, phone’s payment balance, phone financing start date (showing a minimum of 90 days with prior carrier or number of payments made).
