Help & How To

To get started using your device on the T-Mobile network, follow these steps:

 

Ensure device compatibility

  • In order to work on T-Mobile's network, the device must support one of the following frequencies:
    • 850 MHz (2G)
    • 1900 MHz (2G or 3G / 4G depending on location)
    • 1700/2100 MHz (3G / 4G or LTE depending on location)
  • The easiest way to confirm compatibility is using Step 1 of our online compatibility checker.
  • If you are unsure what frequencies your device supports, contact the device manufacturer.

 

Unlock your device

  • In order to work on T-Mobile's network, the device must be SIM unlocked.
  • T-Mobile is only able to provide SIM subsidy unlocks for devices sold by T-Mobile.
  • T-Mobile recommends contacting the carrier the device was originally sold on to request an unlock code.

 

Select the right SIM card

 

Setup internet and picture message settings

  • When bringing your phone from another carrier, internet and picture message settings need to be configured for T-Mobile's network.
  • Some devices are automatically configured for T-Mobile's network when the SIM is inserted.
  • If not, you can manually enter the Internet and picture messaging setting.
    • Note: You may need to contact the device manufacturer to find out where to input the settings in your device.
