This article helps troubleshoot making or receiving calls on your Apple iPhone 5s.

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.

    Airplane mode is a feature that prevents your device from sending or receiving a wireless transmission.

    Turn airplane mode off.

  2. Verify that mobile data is enabled.

    1. From the home screen, tap Settings.
    2. Tap Cellular.
    3. Next to Cellular Data, tap the toggle switch to enable mobile data.
  3. Verify your Apple iPhone 5s is connected to the Sprint network using Safari.

    Some features and applications require a data connection to work properly.

    1. From the home screen, tap Safari.
    2. Try to browse to a web page.
    3. If the data connection fails, update the profile.
    4. Test your device to see if the issue is resolved.
  4. Verify if coverage is available at your current location.

    If your Apple iPhone 5s has low signal strength, see if your location is within Sprint voice coverage on the Sprint coverage map.

  5. Perform a soft reset.

    A soft reset reconnects your Apple iPhone 5s to the Sprint network.

    1. From the home screen, press and hold the Power key and the Home key.
    2. Release the Power key and the Home key when the Apple logo appears.
    3. Your Apple iPhone 5s restarts.
    4. Test your device to see if the issue is resolved.
  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 convenient Sprint Repair center and schedule an appointment so a Sprint technician can further diagnose the issue.

Note: To optimize device performance, be sure your Apple iPhone 5s is running the most recent device software. Check for software updates.
