Travel eSIM Switzerland

Data and plan days only kick in when you arrive in Switzerland. Installing earlier just prepares it for activation which happens automatically when you arrive in Switzerland.

Install over WiFi before your trip to get connected from the minute you touch down.

If you have trouble connecting, see our eSIM Troubleshooting Guide or message us for assistance.

Definitely. Install your Switzerland travel eSIM up to 30 days before departure, and it will activate automatically when you arrive.

Installing early won’t consume data or days from your plan until you land in Switzerland.

If an iPhone shows an activation error when installing abroad, you can safely ignore it - check our eSIM Troubleshooting Guide for guidance.

Not exactly. Once your Switzerland eSIM is active, it’s tied to that country.

If you're visiting more than one place, our regional Travel eSIMs offer broader coverage so you can roam freely across multiple destinations.

Your eSIM will activate automatically when you arrive in Switzerland. Though we recommend installing your Switzerland Travel eSIM before you arrive (this is different to activating).

To do this, scan the QR code we provide or install the eSIM directly from the ZenSim app while connected to WiFi. Once you arrive in Switzerland, your eSIM will activate automatically.

If you encounter any issues check out our eSIM Troubleshooting Guide or contact us directly ☺️

If installed before your trip, it will activate when you land in Switzerland.

If installed after arrival, it goes live right away.

Using a travel eSIM trumps roaming in Switzerland - here’s a quick rundown:

Significant Savings: Pay local Switzerland rates instead of exorbitant roaming prices set by your home carrier.

Convenient Switching: No swapping SIM cards - manage everything digitally from your phone settings.

Usage Clarity: Get real-time updates on data consumption, so you never get billed for data you didn’t need.

Yep! 99% of our eSIMs can be topped up within the ZenSim app with just a couple of clicks. If you run out of data, need more days, or you even want to add a new destination to the same eSIM, you can do all of this in the top up section in the Zen Garden in the app.

Log into the app, navigate to the Zen Garden, and you will see a button to tp up your eSIM right there.

Extending a long trip: If you're travelling for more than 30 days, you can add as many top ups as you need to your first eSIM to extend the days and data you have. Each top up will only take effect when the previous eSIM is expired so you can purchase the top ups any time you want without worrying about overwriting your existing plan.

Multi country top ups: You can now add multiple countries to most of our eSIMs via top up, so if you're in Europe for example and are stopping over in Dubai on the way home, you can add a Dubai top up to your Europe eSIM so you don't need to reinstall anything. Alternate country top ups will only activate when you arrive in the new country.

Yes! Our eSIMs cover more than 200 countries, including Switzerland. We even provide regional eSIMs that span multiple countries in one package - head over to our Travel eSIMs page to learn more.

Our Switzerland travel eSIM is strictly for data; it doesn’t come with a phone number or traditional call/SMS service. Use an internet calling app if you need voice communication.

No, the Switzerland travel eSIM is data - only. It won’t give you a cellular voice line. If you want to call, just fire up WhatsApp, Telegram, or FaceTime using your data allowance.

Connectivity Troubleshooting: Check our troubleshooting guide if your eSIM won’t connect. Still stuck? Hit up our support team and we’ll get you back online fast.
