Troubleshoot issues related to making and receiving calls on your device for the Samsung Galaxy S8+

This article helps troubleshoot making or receiving calls on your Samsung Galaxy S8

You may have issues with calls if you have:

  • A low signal strength
  • Trouble making or receiving calls
  • Frequently dropped calls

These steps help identify and resolve the underlying cause. After completing each step, test to see if the issue is fixed. If not, continue to the next step.

  1. Verify airplane mode is turned off.

    1. From the home screen, swipe down the Status bar with two fingers.
    2. If Airplane mode is enabled, disable by tapping Airplane mode.

      Note: The icon is blue when enabled.

  2. Verify mobile data is enabled.

    1. From the home screen, swipe down the notification panel and tap Settings.
    2. Tap on Connections.
    3. Tap on Data usage to ensure Mobile data is ON.
  3. Verify if coverage is available at your current location.
  4. If your Device has low signal strength, see if your location is within Sprint voice coverage on the Sprint coverage map.

  5. Reset the network settings.

    Resetting the network settings reconnects your phone to the Sprint network and does not erase any of your content or data.

    1. From the home screen, tap the Phone icon.
    2. If necessary, tap the Dial tab.
    3. Enter ##72786#.
    4. Tap OK to confirm.
    5. The phone will restart and Hands Free Activation will begin.
  6. Do you know if other Sprint customers are experiencing the same issue in the same location?

    • If yes or you don't know: Please contact Sprint Customer Care for help.
    • If no: Please find the nearest Sprint Repair center and schedule an appointment so a Sprint technician can further diagnose the issue.

Note: To optimize device performance, be sure your Device is running the most recent device software. Check for software updates.

If you're still having issues, please contact Sprint Customer Care for more help.
