This is not a bug, this is something what can happen after an update if your carrier still has older settings. You will need to perform a carrier settings update in order for this to subside.


See this instructions on how to do that


  1. Make sure that your device is connected to Wi-Fi or a cellular network.
  2. Tap Settings > General > About.
  3. Follow the onscreen instructions to install your carrier update.



Hope this helps!
