You may have text messaging issues if your device is:

• Unable to send or receive text messages
• Displaying error codes or network messages when you try to send a text message

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 your HTC One® is connected to the Sprint network using Sprint Zone.

   Be sure your HTC One is connected to the Sprint voice network to send or receive text messages.

   1. Access Sprint Zone.
   2. Swipe from Right to Left to open Device Diagnostics.
   3. Look for Network:
      • Network is in the Passed section: Your phone is connected to the Sprint network.
      • Network is in the Failed or Flagged section: Update the Data Profile.
      1. From Device Diagnostics, tap System Updates.
      2. Tap Update Profile.
      3. After the profile update is complete, tap OK.

2. Perform a soft reset.

   A soft reset reconnects your HTC One to the Sprint network.

   1. Press and hold the Power key until your HTC One™ turns off.
   2. Your HTC One restarts.
   3. Test your device to see if the issue is resolved.

3. Have you ever been able to send or receive a text message on your HTC One?

   If your HTC One is active and you've never been able to text, contact Sprint Customer Care for further troubleshooting.
