karma_asks Hi! I wanted to buy a phone imported from the US, but it only supports GSM and no CDMA. Will i be able to use this with Sunrise? Is it even relevant? I dont know if that makes any difference but im using a physical sim. Thanks for your support
pato As far as I remember, CDMA only exists in the US and maybe South America. Here we have 3G (UMTS), 4G (LTE) and 5G. GSM is turned off.
