There is no network coverage or mobile data connection

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

  • Turn off your device and then turn it back on. You turn off all running applications and free up memory, sometimes automatically solving the issue.
  • Make sure Airplane mode is turned off.
    1. Find and tap Settings → Network & internet.
    2. Tap the Airplane mode switch to disable the function. You may find the item under Advanced.
  • 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 your SIM card supports. Contact your network operator to know which network types are supported.
    To select a network mode

    2. If you're using two SIM cards, select a SIM card.
    3. Tap Preferred network type, then select a network mode. You may find the item under Advanced.
  • Make sure that your SIM card is working correctly by inserting it into another device. If this works, your device is probably causing the problem. In this case, contact an authorized Sony service partner.

    • Android 12, Android 11, Android 10, or Android 9
      1. Find and tap Settings → Network & internet → Mobile network. (SIMs in case of Android 12)

    • Make sure you have subscribed to use the internet over a mobile network. Contact your network operator for detailed information.

    • When you use your device while moving, you may lose your mobile data connection due to issues with your network provider’s network. Your device is set to select the fastest network available automatically.

  • If none of the mentioned solutions solve the issue

    Verify whether the problem was solved after the first action before trying the next one.

    • Update your device to ensure 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 your device's internal memory. Make sure to back up the data that you want to keep.

      To back up your data using a computer

      1. Unlock the screen of your device and connect your device to the computer using a USB cable.
      2. On the computer, select which files to back up, then copy and paste or drag and drop the files to a location on your PC.

      To back up and synchronize apps, phone settings, and call history

      1. Find and tap Settings → System → Backup. You may find the item under Advanced.
      2. Tap the switch to enable the function. Your app data, device settings, and call history will be backed up automatically.

      You can also enable backup from the settings menu in Google Drive. You can synchronize your app data, device settings, and call history automatically by logging in to the Google account used to synchronize data on your device. When you power on your new device for the first time, log in to the Google account during the setup wizard.

      To perform a factory data reset (Android 14, Android 13, Android 12, Android 11, Android 10)

      To avoid permanent damage to your device, do not interrupt a factory data reset procedure. Save on your device's internal memory, and transfer the internal memory of your device to a memory card or other non-internal memory. If you have any encrypted files stored on an SD card, you should also remove the encryption to ensure you can still access them after the reset.

      1. Back up any important data that is saved on the internal memory of your device to a memory card or other non-internal memory. If you have any encrypted files stored on an SD card, you should also remove the encryption to ensure you can still access them after the reset.
      2. Find and tap Settings → System → Reset options. You may find the item under Advanced.
      3. Tap Erase all data (factory reset) → Erase all data.
      4. If required, draw your screen unlock pattern or enter your screen unlock password or PIN to continue.
