Wi-Fi calling in unlocked device

[bitter]

Hello,

I have an unlocked iPhone 13 (purchased from the US) and started using it with O2 sim last month. I don't have any Wi-Fi calling option on my phone's settings. I tried to make a query to unlock my phone just in case, but received an answer saying my phone is already unlocked. What might be the reason I don't have Wi-Fi calling option on my phone?

Thank you!

You need to have iData enabled on your account and you need to go to your MyO2 to switch on wifi calling.
