Common Questions

The details worth knowing about your Switzerland eSIM

Swisscom uses n1, n3, n7, n28, n78, and n258 for 5G. If your phone lacks n78, you will still get 5G on the other bands, provided your device supports them. n258 is mmWave and rarely supported on foreign phones.

This FAQ is for the Switzerland-specific page, so coverage of neighbouring countries is not addressed here. You would need to check the plan details or the separate country pages for France and Italy to see if cross-border use is included.

No. Many alpine valleys and railway tunnels in Switzerland, including long tunnels like the Gotthard, have no service from any operator. Your eSIM will not work until the train exits the tunnel into an area with coverage.

Swisscom shut down its 3G network at the end of 2025, and Sunrise shut down its 3G network in mid-2025. If your phone relies on 3G, it will not connect to those networks. Salt’s 3G status is not specified in the available facts.

The eSIM can connect to Swisscom, Sunrise, or Salt, all of which support the same 4G and 5G bands. The specific network it lands on depends on your plan and the strongest signal at your location. No single operator is guaranteed by default on this page.
