How do I enable wifi calling? I can't see it in the phone options with the o2 card (it is with other cards, e.g. Three). I do not see this option in My O2 app either. I called the support line on 4445 many times and spoke to about ~5 people. One wanted to sell me another bundle, another did not speak English, another hung up without a word. Two other support guys said within a second that wifi calls had just been activated for my number... but it did not happen. Is this a special feature? Why do other operators give wifi calling by default, but O2 has so many problems? It doesn't make sense... The place where I am, there is not much coverage and I need wifi calls. I'll try again tomorrow and if it doesn't work, I'm giving up and going to another operator....
