I have a Swiss Sim that is enabled for volte and WiFi calling, it worked in an s8, but I don't get either option in my settings. Swisscom say it is Samsung software but I am upto date with the latest release. Anyone any idea what I need to do to enable these options?  Wifi calling, have you checked your router?  Or do you mean VoIP (Voice over Internet Protocol) if you are talking about wifi see if your wifi is connected to a wireless router or hotspot.    If you're talking about VoIP (meaning you're using internet provided by your Cellphone company though cell phone towers) then it might be your APN settings (Access Point Names) sometimes the SIM does automatically automatically or preprogrammed by your provider; sometimes not in such caseyou need to  Go to settings > connections > mobile networks > access point names. See if your phone provider's name if not you'd have to input them manually.  You will need your SIM inserted first.  You can either obtain the APN from your cell company or screen cap the APN information from your previous phone, you may need to do this before you remove the SIM card. It's as simple as typing the information exactly.  ... View more

It may be better just to have more solid space on your phone instead. *Integrated Circuit ... View more
