I notice wifi calling needs to get re-registered from time to time.

I find it works best when you are connected to a decent cellular connection AND wifi connection.

I recommend getting within cellular and and re-set it up

Actually I decided to restart my phone which had I had not done so in while. When retarted, wifi calling was activated. Simple yet…..

Im at the office right now and even with a phone restart it says I cannot complete my wifi calling registration without connecting to wifi.

Well that sucks, best of luck!

Glad mine was so easy on android samsung!
