I am so sorry about the device no longer processing wifi calling. I know I love the benefit of this feature. I would like to help you regain the use of the wifi calling. Please complete the following steps.
- Apps icon > Settings > Network & Internet > Mobile network > Advanced > Advanced Calling.
- Tap Wi-Fi Calling.
- Tap the Wi-Fi Calling switch to turn on.
Once done, please keep me posted on if this fixes the problem.
