Network connection troubleshooting

    Learn how to troubleshoot data connection problems. When you use a 3G, 4G, or 4G LTE-enabled device in a 3G, 4G, or 4G LTE area, the device automatically scans for the best available network. The device will display 3G, 4G, H or LTE next to the signal bars when successfully registered on a 3G, 4G, or 4G LTE network.



    To troubleshoot a network connection issue:


    1. Make sure your device supports 3G, 4G, or 4G LTE. To check, visit the Tech Specs for your device.
    2. Make sure your device has the latest software version.
    3. Check the coverage for your area by using our Personal Coverage Check.
    4. Turn off your device.
    5. Look for your SIM card and make it is inserted properly.
    6. Reinsert the battery and turn on your device.
    7. If you cannot connect to 3G/4G/LTE, perform a manual network selection using your device's how tos.
    8. If possible, see if another T-Mobile 3G, 4G, or 4G LTE device in the area is working properly.
      • If the other device has the same issue, contact us for additional troubleshooting.
      • If the other device does not have the same issue, back up your information and reset your device. Find steps in your device's how tos, under Settings & operating system > Network > Reset.
