To switch to T-Mobile from Verizon, you will transfer your phone number and device to T-Mobile's network by porting your number and activating a new SIM or eSIM. This step-by-step guide covers everything from checking device compatibility and unlocking your phone to porting your number and canceling your old Verizon service.
Before you switch to T-Mobile from Verizon: what you need
Before starting the process, gather your Verizon account number, port-out PIN or passcode, and your most recent mobile bill. You will need these to authorize the number transfer. Also, decide whether you will bring your own device or get a new one from T-Mobile.
How to check your Verizon phone's compatibility and unlock status
Use your phone's IMEI number on T-Mobile's compatibility checker to see if it will work on their network. Your Verizon phone must be unlocked to work on T-Mobile, and T-Mobile cannot unlock it for you. Verizon devices purchased on or after January 27, 2026, are locked until the full device payment or contract terms are fulfilled. If you pay off a Verizon device with a non-secure method such as a Verizon Gift Card or paper check, it will unlock automatically 35 days from payment. Devices purchased from Verizon before January 27, 2026, are automatically unlocked 60 days after purchase or activation.
Step 1: Choose a T-Mobile plan and start the switch
Select a T-Mobile plan that fits your needs. You can initiate the switch online, through the T-Life app, or by visiting a T-Mobile store. Using the T-Life app, the process can be completed in as little as 15 minutes per line, though device activation and number transfer may take additional time.
Step 2: Port your phone number from Verizon
- Provide T-Mobile with your Verizon account number and port-out PIN.
- T-Mobile will submit the transfer request to Verizon.
- Number transfers for wireless lines typically complete within 10 minutes to 3 hours.
Do not cancel your Verizon service until your phone number has been fully transferred and activated on T-Mobile. Cancelling early will disrupt your service and could cause you to lose your number.
Step 3: Activate your T-Mobile SIM card or eSIM
After porting, you will need to activate your new T-Mobile SIM card or eSIM. If using a physical SIM, insert it into your phone. If using an eSIM, follow the instructions to download it. Then complete the activation so the device works on T-Mobile's network. This is part of activating phones and SIM cards on any carrier.
Step 4: Cancel your Verizon service and settle your account
- Confirm that your number transfer is complete and you have service on T-Mobile.
- Contact Verizon to cancel your service.
- Return any leased or financed equipment to Verizon.
- Pay any remaining balances on your account.
How T-Mobile's Keep and Switch reimbursement works
T-Mobile offers to reimburse up to $800 per line (up to 4 lines) for remaining device payment balances from eligible carriers like Verizon. The reimbursement is issued as a virtual prepaid Mastercard. To qualify, you must activate a new voice line, port your number, and submit proof of your device financing details and a final bill showing at least 90 days with the previous carrier and three payments. The virtual prepaid Mastercard typically arrives within 15 days after rebate submission.
What is the Go Back Guarantee?
T-Mobile's Go Back Guarantee allows you to switch back to your previous carrier within 30 days of line activation if you are not satisfied. You will receive a $125 rebate per eligible line.
Frequently Asked Questions
Can I keep my current phone number when I switch to T-Mobile?
Yes, you can keep your existing Verizon phone number. This is called porting, and T-Mobile handles the transfer process for you.
Will I experience any service interruptions during the switch?
There may be a brief period of limited or no service while the number transfer completes, typically lasting 10 minutes to 3 hours. Once the transfer is done, your T-Mobile service will be active.
Do I need to buy a new phone if I switch to T-Mobile?
Not necessarily. If your current Verizon phone is unlocked and compatible with T-Mobile's network, you can bring it with you. If it is not compatible, you may need to purchase a new device from T-Mobile.
What happens to my Verizon device payment plan when I switch?
You are still responsible for paying off any remaining device balance with Verizon. T-Mobile's Keep and Switch reimbursement can help cover up to $800 per line of that balance if you qualify.
How do I transfer my contacts and data to my T-Mobile phone?
You can use cloud services like Google Drive or iCloud, a direct Bluetooth transfer, or third-party apps to move your contacts, photos, and other data from your Verizon phone to your T-Mobile device.
