If you are having trouble with your T Mobile data not working, the below outlined easy-to-follow solutions are for you:

Check your device for 4G band capability

The data issue might be arising due to a 4G band problem. To fix this, you’ll need to check your device’s capabilities and make sure it’s compatible with the 4G bands used by T-Mobile.

Once you’ve verified that your device can connect to the correct 4G band, you can then proceed with troubleshooting other potential causes of the issue.

If you’re unsure how to check your device’s 4G band compatibility, consult your device’s manual or the manufacturer’s website.

Restart your device

Before playing around with your phone and changing settings, ensure that the problem isn’t with your device itself. First and foremost, restart your phone in the following way:

  • Press and hold the power button on your phone for a few seconds until a power menu appears.
  • From the menu, select the Restart option.
  • After your phone restarts, turn on the cellular data and see if this works.

Remove and re-insert your SIM

Try removing and reinserting your SIM card. This simple step can often resolve mobile data issues. To do so:

  • Locate the SIM tray on your device. For most devices, the SIM tray is located on the side.
  • Use a SIM tool or a paperclip to eject the tray.
  • Remove the SIM card from the tray and clean it with a soft cloth or wipe.
  • Wait for some time and reinsert the SIM.
  • If needed, restart your device and turn on the data to see if the issue persists.
