Is anyone familiar with the following situation? My iPhone 6s shows the following problem.

As soon as one side accepts an outgoing or incoming phone call from or to my iPhone there’s only silence as if the connection was dead. But the timer is counting. Before an outgoing call is accepted I cannot even hear the ringing signal.

This only happens with normal phone calls or WLAN calls, but not via Skype. (Therefore, I guess calls via FaceTime, WhatsApp or Threema should be fine too.) It’s all within Germany, BTW. Don’t know about international calls.

Normal audio playback from the phone is also totally fine, whether it’s via speaker, AirPlay or Bluetooth.

The problem only occurs from time to time. Before X-Mas a lot, then it was gone, yesterday the whole day, right now it’s gone…


I did the following things to isolate the problem or to find a solution. None helped:
  • I called my provider during a day when the problem was persistent. From the affected phone I had to call them via Skype. They said they could not find any disturbance/interference, but agreed to send me a new SIM card.
  • I put in the new SIM card and activated it. The problem still occurs.
  • I swapped SIM cards with my wife and we called each other. This morning everything worked, in a few hours it might not.
  • A new battery was put in just before X-Mas.
  • Latest iOS 12.1.2 is installed.
Has anyone heard of the same problem and can say something about the cause and the remedy? I'm not a fan of going to the Apple Store since I don't trust their "The device is beyond repair..." mantra.

Thank you!
