Thanks to unique coverage, outstanding voice quality and high Internet speeds, the multiple award-winning Swisscom mobile network is the best in Switzerland.
With Advanced Calling, you can make calls on your smartphone directly via the 4G/LTE network (Voice over LTE) or any WLAN connection (WiFi calling). The device automatically selects the best available network – whether it’s the mobile or WLAN network. You therefore benefit from a constantly high Internet speed, much quicker call connection times, top voice quality and a longer battery life.
HD Voice (High Definition Voice) is the new audio technology that audibly improves voice quality on your smartphone and eliminates interference, even in a noisy environment. Telephone calls with customers and business partners can now be conducted on the move, since even quiet voices and whispering are clearly audible with HD Voice.
