I live at the foot of a mount, there's forest, the line on my cell phone doesn't work very well in the house but outside it's not so bad. Often, when I go outside, I see some text or voice messages. 

With my old cell phone, an A71, I use the wifi call and it's was a miracle. Thw call rimg inside of the house, no more voice message surprise, it does a big dfference. 

I would like to activate it on my S20 5G but I receive the error message "Call wifi: impossible to set up this fonctionnality". My boyfriend have a S20 5G too and it's work, I don't understand what is the matter.

Maybe someone can help me. Thank you

Enable location services. Switch wifi calling to WiFi preferred. Also make sure that your emergency location service is enabled as well. Otherwise it will not work.
