Why no voice over WiFi preference?

[P1pp5]

Why does EE not offer customers the choice of whether to set their sim card network access to prefer VO-WiFi calling instead of VO-LTE, as other networks rightly do?

@bristolian - Your understanding that the option for WiFi calling is somehow software driven is incorrect.

O2 only offers it on pay monthly accounts and not on PAYG. When I insert an O2 PAYG sim card into my device, I do not have the option. When I then immediately insert an O2 pay monthly sim card into my device, the option immediately appears. 

Clearly, having the option to select a voice over WiFi preference is an entirely carrier determined option which has nothing whatsoever to do with the device. 

So why does EE not offer this option?

And why do EE staff deny it exists?

My previous post, evidenced with a screenshot, clearly disproves this. Some phones have this option, others don't - so there is an element of software control here.

CS are generally geared towards support of common queries, and the vast majority of customers likely have no need for this facility beyond simply enabling WiFi-calling.

I will only respond based on my expertise, and cannot add anything further.

Just to add my 2p worth, my O2 pay monthly sim does not offer the choice in my iPhone 14.

Sounds like you and the defensive EE community is simply doubling down on your self delusion and denial.

Good to know.

I am holding an iPhone 14 in my hands right now which contains an O2 pay monthly sim card that is providing this option for WiFi calling preference. So your 2p is highly questionable and frankly not believable.
