St. Gallen eSIM plans: unlimited, or by the GB.
Every St. Gallen eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in St. Gallen — you can always top up or switch on your next trip.
Unlimited plansHigh-speed data, nothing to count
Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.
- Best for streaming, video calls & hotspot
- Great for longer or open-ended trips
- One price per day — no GB anxiety
A set bundle, brilliant value
A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
- Best value for lighter, shorter trips
- Clear allowance — pay only for what you need
- Top up any time from your phone
How much data do you need in St. Gallen?
A rough, honest guide to sizing your St. Gallen eSIM so you're not guessing. Most travellers in St. Gallen are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.
Everything above plus social scrolling, music, cloud photo backups and a little video. Where most travellers land.
Netflix by the pool, long video calls home and hotspot for the laptop — go Unlimited and stop counting.
St. Gallen eSIM: your local data guide.
The canton of St. Gallen runs from the UNESCO Abbey Library in its baroque capital to the shores of Lake Constance, the thermal spas of Bad Ragaz and the rolling Toggenburg below the Säntis massif. A St. Gallen eSIM keeps you navigating Rapperswil's rose gardens, checking Säntis cable-car times and translating an Appenzeller cheese menu without hunting for Wi-Fi.
Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
Where you'll lean on data in St. Gallen.
The city and its UNESCO abbey precinct have strong 4G/5G for museum times and old-town maps.
The rose town on Lake Zurich enjoys reliable data along its castle and lakefront promenade.
The spa resort and Tamina Gorge are well covered, easing only deep in the gorge itself.
Signal is good in the valley villages but thins on the high Säntis summit and remote ridge trails.
Getting around St. Gallen on your eSIM.
- SBB Mobile— National rail app for trains to St. Gallen, Rapperswil and the Lake Constance line.
- Ostwind— Eastern Switzerland's regional fare-network app for local trains and buses.
- FAIRTIQ— Check in and out for the cheapest automatic fare on regional transport.
- PostAuto— PostBus app reaching Toggenburg villages and Säntis-area trailheads.
Two to four nights suits St. Gallen - the abbey city, a Lake Constance day, a Säntis excursion and perhaps a Bad Ragaz spa stop or Rapperswil visit.
Balanced 3-5 GB covers a week of maps, cable-car apps and photos; light 1-2 GB is enough for a short city-and-lake break of the essentials.
St. Gallen city, Rapperswil, Bad Ragaz and the Lake Constance shore have strong 4G/5G, with coverage thinning on the high Säntis summit, remote Toggenburg ridges and deep in the Tamina Gorge.
