There is no network coverage or mobile data connection

    Hint

    The following steps may differ between Android versions. To learn which Android version your device has, find and tap Settings > About phone > Android version. If you do not see About phone under Settings, tap System.

    • If there is no network coverage, try the following:
      • Turn off your device and then turn it back on. By doing this you turn off all running applications and free up memory, which sometimes automatically solves the issue.
      • Make sure Airplane mode is turned off.

    • Check the signal strength icon   in the status bar to make sure that your device is connected to a network. If the signal is low or there is no signal, move to an open location, or get close to a window.
    • If your device is not receiving any network signal, or the signal is too weak, contact your network operator and make sure that the network has coverage where you are.
    • Make sure you have set your device to use the network type that your SIM card supports. Contact your network operator if you don't know which network types are supported.

    • Make sure that your SIM card is working properly. Insert your SIM card in another device. If this works, it is probably your device that is causing the problem. In this case, contact the nearest Sony Mobile service center.
    • Search for a network from the device to check if any networks are available.

    • If there is no mobile data connection, try the following:
    • Turn off your device and then turn it back on. By doing this you turn off all running applications and free up memory, which sometimes automatically solves the issue.
    • If your device supports STAMINA mode, deactivate it and restart your device. To save battery power, STAMINA mode disables mobile data when the screen is turned off.

    • Make sure you have subscribed to use the internet over a mobile network. Contact your network operator for detailed information.
    • Move to another area and try again. In areas with poor reception where there may be issues with your network provider's base station, you may lose your mobile data connection and therefore need to move to a different area.
    • When you use your device while moving, you may lose your mobile data connection due to issues with your network provider’s network.
    • Manually set your device to only use either a WCDMA (3G) or GSM (2G) network. Your device is set to automatically select the fastest network available. If the signal strength of the fastest network is unstable, the device may repeatedly switch back and forth between mobile networks. Each time the device switches network, connection is disabled. If you set your device to use only a WCDMA (3G) or GSM (2G) network, note that it may take several minutes until your device connects to the selected network.

    • If none of the mentioned solutions solved the issue, try these actions one after the other. Verify after the first action whether the problem was solved before trying the next one.
      • Update your device to ensure that you have optimal performance and the latest enhancements.
      • Perform a factory data reset. This is sometimes the best solution if your device stops functioning properly, but note that it will delete all personal content saved on the internal memory of your device. Make sure to back up data that you want to keep.
