Just got an O2 sim only, I have enabled WiFi calling, but now I'm told
that because I bought it from Samsung I can't have WiFi calling. Is this
true? Is there a way to fix this, or do I have to go back to Vodafone?
I have just been told by o2 that it does have to be from o2 and running
o2 firmware! There certainly isn't an option to use WiFi calling on the
phone in the communication settings. I've already been through your
link. That is why I'm asking.
