I bought my phone from Samsung direct and I noticed the wifi calling wasn't showing (I'm on Vodafone). I tried texting the number that is supposed to turn it on but that didn't work, but a quick call to 191 and they sent something over the air that sorted it. Pretty glad because for some reason for the last few months I have poor Vodafone signal where I live.
To turn it on I went into the dialler and then there is a wifi calling option in the settings, this is what wasn't appearing before Vodafone did something when I called them.
