Last Updated: Mar 04, 2016

This article helps troubleshoot making or receiving calls on your Samsung Galaxy S7

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, tap Apps.
    2. Scroll to and tap Settings.
    3. Tap Connections.
    4. Scroll to and tap Airplane mode.
    5. If Airplane mode is On, tap the Airplane mode switch to Off.
  2. Update your Sprint data profile.

    The data profile contains settings your phone needs to connect to the Sprint network.

    1. From the home screen, tap Apps.
    2. Scroll to and tap Settings.
    3. Scroll to and tap System updates.
    4. Tap Update profile.
    5. After the profile update is complete, tap OK.
  3. Verify if coverage is available at your current location.

    If your Samsung Galaxy S7 has low signal strength, see if your location is within Sprint voice coverage on the Sprint coverage map.

  4. 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 Phone.
    2. Enter ##72786#.
    3. Tap YES.
    4. The phone will restart and Hands Free Activation will begin.
  5. 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 Samsung Galaxy S7 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.
