Ihr vermerkt in der Beschreibung das 5G freigegeben ist, anscheinend ist es aber noch nicht der Fall. Ich habe aus engen Kreisen folgende Meldung erhalten: As I work for a telco I was able to contact a colleagues at Sunrise UPC who works in the mobile department and learned that they have tested the Fairphone 4 and found Issues with VoLTE, Wifi Calling and 5G. Therefore they intentionally disable those features when a Fairphone 4 logs into their mobile network. They are in contact with the manufacturer of the Fairphone 4 to solve those issues but it has no priority as this is not a phone they sell or advertise themselves. Hat jemand Erfahrung mit Fairphone 4 mit dem 5G Netz von Sunrise
