Wifi calling - which UK network to choose

I have a new FP4 and I have just moved house to find that I have rubbish signal with Giffgaff. Giffgaff don’t support wifi calling and so I want to switch to another network who do support wifi calling. However, none that I have asked (O2, vodaphone, smarty) can confirm whether they can support wifi calling with a FP4. So, my question is, does anyone have wifi calling working on their FP4 and if so, which network are you with? Thanks so much
