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. Turn off your device, remove and then reinsert the battery, and then turn the device back on.
    2. Check the coverage for your area by using our Personal Coverage Check.
    3. Look for your SIM card and make it is inserted properly.
    4. Make sure your device supports 3G, 4G, or 4G LTE. To check, visit the Tech Specs for your device.
    5. Make sure your device has the latest software version.
    6. If you cannot connect to 3G/4G/LTE, perform a manual network selection using your device's how tos.
    7. If possible, see if another T-Mobile 3G, 4G, or 4G LTE device in the area is working properly.
