Check Phone
Find out if your phone is locked or unlocked
Your phone must be unlocked to get Mint Mobile service. If you are on a prepaid or pay-as-you-go plan, your phone is probably already unlocked. If you aren't sure, the most reliable way to find out is by calling your current (cough, expensive) carrier.
How to unlock your device
If you're making payments on your phone through another carrier, you will have to pay off the remaining balance before bringing your phone to Mint. Once your phone has been fully paid off, your carrier is legally obligated to unlock your phone for free.

If you’re still not sure if your phone will work with Mint Mobile service, visit Once there, enter your phone’s brand and model, U.S. for country and, under “Carrier,” choose our partner company, Ultra Mobile. (This, however, does not guarantee if the device is unlocked or that the phone will work with our service).

Can I get a new phone number with Mint Mobile?

Yes, you can request a new number during the SIM card activation process. You will need to enter your zip code and choose the option, “Get a new number.” A new number will auto generate based on the zip code and availability in your particular area code.

Any resemblance your new number bears to the geographical coordinates of the Lost City of Atlantis is purely coincidental.

How do I transfer (port) my phone number to Mint Mobile?

To transfer—or port—your phone number during activation, you’ll need to authorize the release of your number to Mint Mobile. To do this, you will need:

  • Your account number from your former carrier. Your account number can be found on your billing statement, or acquired by contacting your provider’s customer service department.
  • The corresponding password, pass code or PIN code number.
  • The zip code associated with the account.

There is no fee associated with transferring your number.

Please remember that your phone number transfer can take up to 48 hours to complete. If you have any questions regarding your port, email Once the number has been successfully transferred, we will we send you an SMS and confirmation email.

How do I know if my phone is unlocked?

If you’re on a prepaid or pay-as-you-go plan, your phone is probably unlocked; however, if you’re on a two-year contract or something similar, your phone is probably carrier-locked until you finish paying it off.

The most reliable way to determine whether or not your phone is unlocked is by calling your current carrier and asking them to verify your phone’s status. You will most likely need to provide your account password (if applicable) and your phone’s IMEI number. You can find this on most phones by dialing *#06# on your keypad.

Phones need to be unlocked prior to activating your Mint Mobile service.

Can I transfer my number over to Mint after I have activated my SIM?

Unfortunately, no. You need to transfer your number over at time of activation.
