I bought the S20 Ultra direct from Samsung, my colleague has the S20+ direct from Samsung. Why is it she has WiFi Calling but I don't?

It uses WiFi to make phones without having to use 3rd party apps like WhatsApp or Messenger. Alot of my family don't have smart phones.

We both work for O2 so have o2 sims. She does however have a tesco sim card in the second slot so if it's network dependent then I guess her Tesco sim is giving the option for wifi calling even though the signal provider is o2🤔

If may be something you need to contact your service provider about to switch on if needed.
