Hello,Account is post-paid, Blackview is in use at the moment, VoLTE seems active on account.In settings Koodo network is selected,Prefered network is 4G,Wifi calling is activated,Calling preference is Call over Wifi,but I don’t see anything indicating to enter a code or such…My home Wifi speed is over 100M.My cell signal at home keeps jumping from 4G (1-2 bars) to 3G (1-2 bars).Never was able to call over wifi before… 2 days ago we had no cell service on all our phones and no way to use wifi to call, next day cell service was back…Sooooo, how do I get to make calls over wifi?Thanks.
