Has anyone managed to use WiFi calling with the OnePlus 8 Pro? I can't get it to work and would appreciate any tips. In the settings under WLAN & Network - SIM & Network - SIM 1 - Improved communication, you should be able to switch on VoLTE and WiFi. However, these menu items were not available for me. I had to change this first with the following instructions, which is pretty bad. https://www.theandroidsoul.com/how-to-enable-volte-and-vowifi-on-oneplus-7-pro/ After that, I was able to activate WiFi calling and restart the device. Unfortunately, it still doesn't work. I went to Sunrise and found out more there. My SIM card supports WiFi calling and it worked fine with my previous smartphone (Huawei 20 Pro). If you research Sunrise, they also state that the OnePlus 7 is supported for WiFi Calling, but not the OnePlus 8, see the link below. https://www.sunrise.ch/de/privatkunden/hilfe/mobile/mobile-einrichten/hardware-support.html?seite=topic/wlan-anrufe-wi-fi-calling/wlan-anrufe-aktivieren/device/oneplus WiFi calling is an important feature and on such an expensive smartphone, it simply has to work. If this issue cannot be resolved, I strongly advise against buying it! Does anyone have any further insights on this topic?
