You land at Zurich (ZRH) after an early flight, and the first thing you want is to check the train times to Lucerne. Or you arrive at Geneva (GVA), tired but ready for a week in the mountains, and you need to message your family that you have landed. With a Slashtel eSIM, you can get online as soon as you switch it on. No queueing for a local SIM, no hunting for a shop in the terminal.
Slashtel sells data-only eSIMs for Switzerland. You buy online before you travel, and your QR code arrives by email within a minute. Install it at home on Wi-Fi, and it activates when it first connects in Switzerland. Prices start from $1.79, with no contract and no local address needed. It is just data, so no local number, calls or SMS. But you can use WhatsApp calls over data, and hotspot is allowed. Top-ups are done online on the same eSIM.
UK travellers often head to Switzerland for ski trips and rail holidays. Whether you are catching the Glacier Express or hitting the slopes in Zermatt, you will want data for maps, train schedules and sharing photos. A data-only eSIM keeps you connected without touching your UK roaming bundle, which may not cover Switzerland the same way as the EU.
Indian travellers visit for holidays and honeymoons, drawn to the scenic trains, lakes and mountain views. You might start in Zurich, spend a few days in Interlaken, and finish in Geneva. Having data means you can navigate, translate, and stay in touch with family back home. And because you keep your Indian SIM active, you can still receive bank OTPs and calls.
| Data | Duration | What it covers |
|---|---|---|
| 1GB | 3-5 days | Maps, WhatsApp text, light email. No video. |
| 3GB | 1 week | Maps, WhatsApp calls, occasional social media. |
| 5GB | 2 weeks | Maps, WhatsApp video, some music streaming. |
| 10GB | 1 month | Daily use including video and video calls. |
For a 1 week trip, 3GB is usually enough if you stick to maps and messaging. If you plan to stream music or make video calls, go for 5GB or more.
Switzerland is not in the EU, and some UK and EU roaming bundles treat it differently, so check before you travel. If you rely on your home SIM, you might face extra charges or reduced speeds. A Slashtel eSIM avoids that uncertainty.
Mountain railways and tunnels can briefly interrupt signal. You might lose connection for a few minutes as you pass through a long tunnel or deep valley. That is normal. Download offline maps and music before you set off, so you are not caught out.
Install your eSIM at home while you have Wi-Fi. Follow our installation guide for step-by-step help. Your home SIM stays in your phone for calls and OTPs. If you are an Indian traveller, see our guide on keeping your Indian SIM active. That way, you can still receive bank codes and calls from home while using the eSIM for data.

For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Switzerland is $5.59 on Sunrise, Salt and Swisscom. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
