  • Verify Your Current Phone’s Eligibility

T-Mobile offers a range of phones, both Apple and Android, eligible and compatible with its network. When you want to switch your carrier network, you should first check its eligibility in T-Mobile stores. 

The current phone you have may be eligible, and you can keep it for use after switching. Also, you can decide to buy or trade your current phone for a new one. 

T-Mobile offers a Keep and Switch claim, a device payment reimbursement from your previous carrier. However, the application for a refund is open 30 days after activating your T-Mobile line. Also, there are several qualifications you will need to meet for the network to approve your request. 


  • Screenshot Your Current Device Payment Plan Balance from AT&T 

During the switching process, you will need to show the payment plan of your device while you were using AT&T. T-Mobile network requires this information to keep track of your device payment during trading-in or buying from the network.

The network will also require the payment plan to apply for a rebate on your device when you submit it. 

  • Pay Off Your Device to AT&T

When you complete paying your device off to AT&T, you may request for unlocking of the device. You can check the installment payment plans from your AT&T account to know how much you have left. Paying off your device fully increases your chances to receive reimbursements, allowing T-Mobile to track device payments after switching. 

Once you finish paying, wait for 24 hours to request unlocking the device from AT&T. 

  • Request Unlocking of the Device from AT&T

AT&T SIM locks their devices to protect them from theft, making sure these devices only work on the AT&T network. Therefore, you will need to unlock the device from the AT&T network when switching to T-Mobile. 

To unlock your phone, go to their website and select unlock your device to follow the instructions for unlocking your device. After the request, you will receive a text in 1 to 3 days to confirm that the process is complete. 

  • Order Your SIM Card from T-Mobile

After completing the unlocking process, you can now pick your line or SIM card and select your data plans. Call the network to receive your number when you receive the SIM card so that they activate your new network. 

Sometimes, you may need to retain your number from your previous carrier as a personal preference. T-Mobile can help you transfer the number to their network service when you submit your ID, account number, and PIN. 

The ID can be either a state-issued ID or driving license, your passport, or a military ID card. You can find the account number in your current carrier bill. Your PIN is the last four digits of your mobile number or social security number, not in your online account. 

However, if you still have issues finding the necessary information, contact T-Mobile customer care to direct you. 

  • Submit Your Request for a Rebate as You Sign Up for a T-Mobile ID

The request for a refund is set for 30 days after activating your line. Additionally, there are several needs the network requires you need to meet to be eligible for reimbursement. You will also need to submit your new SIM card and the screenshot of your device’s payment plan.

After qualifying for reimbursement, you will receive a virtual prepaid card within 15 days to pay the necessary funds. It will take 24 to 48 hours after the 15th day for your account to top up.

Therefore, you will receive a T-Mobile ID alongside the funds after successfully switching to T-Mobile.
