Yes — Swisscom provides 4G across the village, chairlifts, and groomed runs. Salt Mobile is thinner on the upper slopes. The Augstenberg back bowl and off-piste zones lose coverage in pockets. Download your piste map and avalanche bulletin before you leave the base lodge.

Partially. The trail starts with 4G near Gaflei, then loses signal in forested sections for 30–60 minutes at a time. The ridge above 1,400 metres regains LTE intermittently where you have line-of-sight to valley towers. Download offline maps before you start.

Yes — both Swisscom and Salt hold 4G at the castle and the old town below. The hiking trail to Fläscherberg climbs into LTE-only territory after the first kilometre, and the ridge above 1,400 metres loses signal in forested stretches.

Two to three gigabytes covers live weather updates, the LIEmobil bus app for shuttles to Vaduz, WhatsApp calls, and occasional navigation. Add another gigabyte if you plan to stream music on the lifts or upload photos from the slopes each evening.

Yes — WhatsApp voice and video calls work over the data connection. Swisscom and Salt both provide low-latency 4G and 5G in the Rhine valley, so call quality matches what you would get on Wi-Fi. Expect occasional drops in the high mountains where coverage thins.

Around 10–20 megabytes for real-time schedules, route planning, and mobile ticket QR codes. The app refreshes arrival boards every few minutes and generates a new QR code for each journey, so it needs live data throughout your trip — Wi-Fi-only mode does not work for ticket validation.

Swisscom offers 5G across the capital with speeds around 80–120 Mbps in the town centre. Salt Mobile provides strong 4G with slightly lower speeds. Both carriers cover the castle, pedestrian zone, and museums reliably. Swisscom has a slight edge in the mountains, but the difference is minimal in the valley.

Swisscom maintains 4G at Malbun ski resort and most alpine villages. Salt Mobile is thinner on upper slopes and high ridges — you may drop to LTE or lose signal in back bowls. For serious hiking or backcountry skiing, Swisscom is the safer choice.

Yes — the app loads business listings and contact details over your data connection. It uses minimal bandwidth, around 5–10 megabytes per day if you are looking up restaurants or services frequently. The app works identically to how it would on a local Swiss SIM.

Yes — MeteoSwiss covers Liechtenstein with the same granularity as Swiss regions. The app pulls radar, hourly forecasts, and avalanche bulletins over your eSIM data. Expect around 20–30 megabytes per day if you refresh forecasts multiple times, more if you load animated radar loops.

A Swiss SIM from Swisscom or Salt works identically in Liechtenstein because the principality uses Swiss infrastructure. The eSIM skips the errand of visiting a shop in Buchs or Sargans, activates the second you cross the border, and does not require you to manage a physical card or return it when you leave.

Yes — Swisscom and Salt both provide cross-border coverage into Feldkirch without interruption. Your eSIM treats the border as a domestic handoff, so you stay online at the train station, the old town, and the shopping streets without a roaming charge or manual network switch.

Yes — Buchs sits in the Swiss network footprint that Liechtenstein shares. Your eSIM connects to Swisscom or Salt on both sides of the border with no roaming fee. The train station, Rheinpark mall, and the road to Sargans all hold 4G or 5G continuously.

Yes — hotspot is enabled by default. You can tether a laptop, tablet, or a companion's phone without throttling on the first few gigabytes. Useful if you are working remotely from a Vaduz café or sharing navigation with a travel partner whose device does not support eSIM.

Yes — the route from Zurich to Sargans and onward to Liechtenstein runs through Swiss network coverage. Swisscom and Salt both provide 4G or 5G along the entire rail corridor. You may drop to LTE briefly in tunnels, but the connection recovers within seconds of exiting.
