So i have recently joined iD Mobile and I'm having issues with wifi calling as in it seems to disappear from my settings when i enter the id sim. Previously on vodafone where i have an option to turn wifi calling on/off. No option on id mobile. I signed up to id because it says it offers wifi calling to galaxy s7. This is a must have as my workplace is an old remote building with no coverage. Is wifi calling even available or is it wrongfully advertised?
