Unlimited plans for 3, 5 and 7 days: which one suits you?

If you’re travelling to Switzerland and know you’ll be making heavy use of your phone — maps, cloud photos, video calls, social media — an unlimited plan is the option that gives you the most peace of mind. No checking how many GBs you’ve used, no fear of running out of data halfway through your trip.

Unlimited 3 days – €5.95

Perfect for a long weekend in Geneva, Zurich or Interlaken. Three days go a long way if your trip is short and action-packed. It’s the most affordable unlimited plan in the range.

Unlimited 5 days – €9.99

The ideal option for a short week or a bank holiday break. It covers you from arrival to departure with room to spare, and the price per day is very competitive. This is often the plan chosen by travellers combining two or three cities.

Unlimited 7 days – €13.95

A full week of unlimited data. If you’re planning to travel across several Swiss regions or tackle mountain routes with constant navigation, this plan is the most comfortable choice. For under €14, you get seven days without a care.

When is it worth choosing a GB plan instead of unlimited?

Not everyone needs unlimited data. If you’re connected to your hotel or accommodation Wi-Fi for most of the day, or if you only need your phone for occasional navigation and WhatsApp, a 1 GB (€1.95) or 5 GB (€5.99) plan may well be enough.

On the other hand, if you’re planning to stream content, share lots of photos in real time or work remotely during your stay, the unlimited plans are better value for money and spare you the feeling of having to ration your data on holiday.

Why choose a Roam2Go eSIM for Switzerland?

Switzerland is not part of the European Union, which means the EU roaming that many Europeans use in other countries does not apply here. This means that if you travel with your regular SIM, you are very likely to be charged international roaming rates — which can be high and difficult to predict.

With a Roam2Go eSIM for Switzerland, you know exactly what you’ll pay before you leave: a fixed price in euros, with no surprises on your phone bill when you get back. What’s more, activation is instant and you can do it from the comfort of your sofa, without waiting for a physical card or visiting any shop.

Other practical advantages:

• Compatible with most current phones that support eSIM (iPhone XS and later, many Android devices). Check the list of compatible phones if you’re unsure.
• Your regular physical SIM can stay active for calls and SMS on your number, with its data roaming switched off. As Switzerland is outside the EU, your provider’s voice and SMS roaming is normally switched off by default (if you want it, you have to ask for it) and, if it’s on, you may be charged for calls you make and receive and for SMS.
• No contracts, no commitments: just choose the plan you need and that’s it.
• Support available in English if you have any technical questions.

Practical tips for staying connected in Switzerland

Switzerland has a very advanced telecommunications infrastructure, and coverage in urban areas and along the main tourist routes is generally excellent. That said, if you’re planning high-altitude hiking or heading into remote valleys, bear in mind that coverage may be more limited — that’s down to the nature of the terrain, not the plan.

A few useful tips:

• Download offline maps (Google Maps or Maps.me) before leaving areas with coverage.
• If you’re heading into the mountains, let someone know your route in case you pass through areas with no signal.
• Activate your eSIM on the day of departure or even a day before to make sure everything is working properly.
• If you have any questions about activation, check our guide on how an eSIM works.
