What is the best eSIM for Switzerland?
+
For travellers who want Swiss mobile data on the phone they already own, eSIMbundle is a strong option — especially because Switzerland sits outside standard EU roaming rules for many home carriers. Buy a Switzerland bundle before departure, land at Zurich, Geneva or Basel, and use Google Maps, SBB Mobile and WhatsApp straight away. A VPN is included with every plan.
Which mobile network does eSIMbundle use in Switzerland?
+
In Switzerland, eSIMbundle connects to Salt and Sunrise. Your eSIM switches automatically to the fastest available network for the best coverage and speed, so you never need to choose a carrier. All of them support 4G and 5G.
Does eSIMbundle have good coverage across Switzerland?
+
Coverage is generally comfortable across Zurich, Geneva, Basel, Lucerne, Bern, Lausanne and Interlaken and along the main SBB rail corridors. Signal can weaken inside long Alpine tunnels, on mountain-pass roads, on high hiking trails and in remote valley floors.
Is 5G available with a Switzerland eSIM, and how fast is it?
+
4G and 5G are broadly available across populated Switzerland and generally strong across the large city centres and main rail routes. Whether your phone connects on 4G or 5G in a specific spot depends on your device, the available partner network and live local conditions.
How much data do I need for 7, 15 or 30 days in Switzerland?
+
Light users on Maps and messaging often manage on 1–3 GB a week. Normal travellers using SBB Mobile, translation, streaming and hotel bookings usually want 5–10 GB a week. Heavy video or hotspot users on long train journeys can push past 20 GB a week. Use the Travel Data Calculator to size a Switzerland plan for your trip.
Does a Switzerland eSIM include a Swiss phone number, calls or SMS?
+
eSIMbundle Switzerland plans are data plans. Use mobile data for WhatsApp, FaceTime and other internet-based calling and messaging. Keep your normal SIM active for calls, SMS and verification messages, subject to your home carrier's roaming charges and support.
Can I keep my normal SIM, phone number and WhatsApp?
+
Yes. On a compatible dual-SIM phone, keep your normal SIM installed and use your eSIMbundle eSIM for mobile data. Your normal phone number stays with your home SIM, and WhatsApp continues using the number already registered to your account.
Can I add more data while I am in Switzerland?
+
Yes. In the eSIMbundle app, open Store or Add data and buy a separate bundle on the same installed profile. Each bundle has its own allowance and validity and may wait before first use. Eligible finite bundles offer saved-card auto top-up at 80% used, up to your approved package price. Manage it under Account → Auto top-up; check existing replacement orders before buying again.
Should I buy my Switzerland eSIM before travelling?
+
Yes. Open the eSIMbundle app → Account → My eSIM → Set up your eSIM and use Install eSIM on this phone, or QR/manual fallback. Confirm the profile appears in phone settings. Installation does not start the bundle; first supported use in coverage does. At your destination, enable the line, select it for data and enable its Data Roaming setting. Keep the profile after the trip.
Does eSIMbundle include a VPN in Switzerland?
+
Yes. Use VPN inside the eSIMbundle app with your normal account. VPN connection requires an active qualifying bundle, including on Wi-Fi. Prepare the app before departure; a bundle awaiting first use may not yet provide access. Choose a country and connect. VPN does not guarantee access to every service.
Does the eSIM work on mountain trains and Alpine trails?
+
On mountain railways and hiking trails, coverage from any Swiss carrier — including your eSIM partner network — can weaken inside long tunnels, in deep valleys and on remote peaks. In populated cantons and along the main SBB corridors, everyday service is generally comfortable. Downloading offline maps for a big hike is worth the extra minute.
Can I use the same eSIM on my next trip elsewhere?
+
Yes. Your eSIMbundle eSIM stays installed on your phone. When you travel to another supported destination, add a bundle for it in your account and it activates on the same eSIM — no new installation required.
