You'll probably need customer service to activate it first on your account.

Hello, I had the same question for my P20 as i also live in an area that has poor O2 reception.
i have found in the O2 app that you have to add to yiur account. I have turned it on and will wait 24 hours
So its Manage your account>view all>Device Details>Wifi and 4G Calling> Activate button
hope that helps and that it works
