I have an s20 and I keep having to setup wifi calling. Sometimes it will stay on for a few days then other times it will ask me to set it back up like 2 hours later. Anyone have this issue or a solution?
I think, sadly, you have no replies because no one is experiencing this problem. I've been successfully using wifi calling for years and just don't have an answer for you, I'm sorry. Maybe reset your device completely if that's an option.
