iPhone 14 support 5G and Wi-Fi calling

SMARTY does not currently support 5G and Wi-Fi calling on the latest iPhone 14 range. It therefore would  be a BIG step-down in terms features for many customer’s that are planning to upgrade their mobile phone or receiving new phones as Christmas presents.
Unlike the USA model, the iPhone 14 range of phones in the UK does still have a SIM Tray, so SMARTY not supporting an eSIM would not be a deal breaker here?
On speaking to Customer Service at SMARTY I have been advised that you are waiting for Apple in order to move this forward, yet the Apple website shows that the 3 network infrastructure does already support both of these features already?

EDIT 8/12/2022

SMARTY has a slogan of simple, honest mobile. However, this question hasn’t been answered by anyone at SMARTY, and further questions other topics have been posted afterwards, which have been answered?

I’d like to upgrade my phone, but so far I’m getting the generic response of “we are adding new phones all the time”, but no actual indication whether this phone will be indeed be added, despite the fact it is already has 5G and Wi-Fi calling on 3?
If it’s a case that 3 won’t let you do this, then why not be honest? Not answering the question or giving a response that is non committing is not really demonstrating this?  Other MVNOs with other network providers do have iPhone 14 compatibility.  New phones from other manufacturers are supported by SMARTY
