Metro by T-Mobile Phone Unlock Policy

Unlocking your mobile wireless device

Most mobile devices are programmed to prevent the device from operating with other wireless carriers’ networks without first being unlocked. We're committed to providing you with clear information about unlocking your mobile device.  

If you purchased your device from Metro by T-Mobile or if you have a Metro by T-Mobile authorized device, please follow the steps outlined below to determine your eligibility for device unlocking. In order to unlock a mobile wireless device that is not sold or authorized by Metro by T-Mobile, you need to contact the mobile carrier or manufacturer that sold you the device.


Metro by T-Mobile’s approach to device unlocking

Once a device becomes eligible for unlocking (eligibility requirements are described below), Metro by T-Mobile will automatically and remotely unlock the device within two business days if the device supports remote unlock.

Some devices cannot be remotely unlocked by Metro by T-Mobile. In these cases, Metro by T-Mobile will send a notification to the device within two business days of it becoming eligible, with next steps to complete the unlock process.

If you received a notification that your device is eligible to be unlocked, and you need instructions for completing the unlocking process, click here.

Unlock eligibility requirements

We unlock mobile devices that meet the following eligibility criteria free of charge:

  • The device must be purchased from Metro by T-Mobile.
  • The device must not be reported as lost, stolen or blocked.
  • One hundred eighty (180) days must have passed since the device’s activation date.


About deploying military personnel

Military personnel who are pending deployment do not have to meet the 180-day requirement described in the previous section. To unlock their Metro by T-Mobile device, military personnel (or family members) must visit a Metro by T-Mobile Store with their deployment papers.

Frequently Asked Questions

  1. What does my phone being ‘unlocked’ mean?
    A device unlock enables your Metro by T-Mobile device to use a non-Metro by T-Mobile SIM card to connect to a different international or domestic network. This may also be known as a SIM unlock, network unlock, or carrier unlock.

  2. When can I unlock my phone?
    Your phone can be unlocked when you are eligible for unlock. Please see Metro by T-Mobile’s policy for more details.

  3. What happens if I don’t unlock my device?
    Nothing! Your phone will continue to work just as it does today.

  4. Why do I have to wait 180 consecutive days?
    As a pay in advance service provider, this helps us reduce fraud and misuse of service. This is in line with industry standards for pay in advance services.

  5. When does the service requirement (180 consecutive days) start?
    The service requirement begins from your phone’s activation date. The first day your phone is active with Metro by T-Mobile counts as day 1. Please note that your phone’s activation date is different from your account’s activation date.

    Note: For phones under warranty exchange, the activation date is the date you originally purchased the phone, not the activation date of your warranty exchange handset.

  6. Is there a fee for requesting a device unlock?
    No. We unlock mobile devices that meet eligibility criteria free of charge.

  7. What do I do if I received an error using the Device Unlock app?
