WiFi Calling... How does it work? OK, an oldie here so be kind and simple in any explanation i.e. no acronyms 😁I was thinking about how WiFi Calling actually works 🤔 With iD call plans certain numbers are ‘charged’ (084, 087, 09, 118 etc) and I was thinking that if a ‘charged’ call was connected through WiFi Calling only then surely it should be ‘free’ as you are not using iD mobile network for that call?!?!? Or are you not able to use one without the other?For example. I am with iD Mobile with regards to unlimited calls and texts with 5GB data/mth plan BUT if I used WiFi Calling to phone a ‘paid for’ number would it be free as my broadband supplier is BT and the call would be placed over their internet connection (at home).I kind of understand that iD would be involved at some point, initially, but if I turned off my data and VoLTE, WIFi Calling would connect the call via my BT broadband and so how could iD be able to charge for the call when it doesn’t use their network??Just a thought and any help is appreciated!
