I have enabled wifi calling option in the menu by running the #*#869434#*#* code and turning on the wifi calling option in the carrier settings. However, on turning airplane mode on and enabling wifi I can't call any number on the phone app. It says no network connection. I don't see any wifi calling icon on the status bar. I am currently on Xiaomi.eu ROM and using sky mobile. Please can anyone help?

First you should ask your provider if your phone number can use the VoWifi feature or not. 
- If the answer is no, you can't do anything except changing provider or plan.
- If the answer is yes, your device is maybe not compatible with this carrier (for the VoWifi only). I don't think you can do anything to fix that so you should try another provider.

Hello, I have the exact same problem. In my case, VoWiFi was working perfectly with the first Xiaomi.eu fastboot build for the K40.
After I updated to a newer version, it stopped working completely. I tested my SIM on another device and VoWiFi works fine.
