The most likely cause of this is that your default SMS/MMS app is malfunctioning and not allowing other apps to see the message. To fix this, you will need to switch to a new SMS/MMS app. Here's what to do:

  1. Select a new SMS/MMS app from Google Play, then download and install it.
  2. Run the new SMS/MMS app and follow its on-screen instructions to set it as the default app.
  3. Uninstall or disable the old SMS/MMS app.
  4. Reboot your phone to ensure that the change takes effect.
