WiFi Calling Compatibility non-O2 Xperia 1 iv (XQ-CT54)

[j3r0n1m0]

Hello Community,

I'm considering switching to O2 but I do require my current phone to be supported for WiFi calling. Is there any way to know for sure if the phone will work with WiFi calling on the O2 network?

The phone is an Xperia 1 iv 5G "dual"-SIM (1 removable sim and 1 eSIM), model number XQ-CT54. I purchased the phone unlocked and contract free from a UK dealer.

If this information helps: I have tried using WiFi calling on other networks with mixed results. On Three it does work very well (but outdoors signal on my area is apalling, so it is not an option for me) but in Vodafone it does not work at all (WiFi calling option doesn't even show in the menus).

Looking forward to hear from you.

Once O2 have enabled wifi calling on your account you will be fine and able to turn it on in your MyO2.
