Interlaken eSIM packages

Prices may change. Always check the product page for the latest prices.

Essential and Plus refresh high-speed allowances daily. Premium has one total high-speed pool across five days, so it is not a full-week alternative. Fixed packages provide one total allowance.

Arriving at the right Interlaken station

Check whether your accommodation and onward booking use Interlaken West or Interlaken Ost. Save the exact station, connecting service and final walking route before travel. Check your actual airport-to-Interlaken itinerary in the rail operator's current journey planner rather than relying on a fixed travel-time estimate.

If travelling onward toward Lauterbrunnen, Grindelwald or Jungfraujoch, keep each connection and return arrangement with your booking. Download tickets in the operator's accepted format and confirm any reservation requirements separately.

Prepare your days around the lakes and valleys

• Harder Kulm: save your booked departure point and return arrangements, and check current operating information.
• Lauterbrunnen: keep your accommodation or meeting address with the onward route.
• Grindelwald: distinguish the village arrival stop from the departure point for your chosen activity.
• Lake Thun and Lake Brienz: save the exact pier, destination and return sailing. Check ticket and pass conditions with the operator.

For paragliding or another booked activity, keep the actual provider's contact and meeting instructions accessible offline. Follow its current weather and safety guidance. A mobile connection helps with updates where service exists; it does not establish that an activity is operating.

Swiss networks, not a mountain-signal promise

AloOui confirms Swisscom, Salt and Sunrise support across the Switzerland country-product range, including Premium, with 4G/5G where available. Actual reception varies with the device, terrain, buildings and network conditions.

Coverage at every Jungfraujoch location, tunnel or mountain-rail segment is not guaranteed. Save essential maps and tickets offline. For detailed preparation, see the Swiss mountain-connectivity guide; for network and allowance records, use the Switzerland connectivity reference.

Choose data for your actual trip

Compare fixed 5GB for lighter use alongside Wi-Fi, Essential for balanced daily browsing and messages, and Plus for heavier daily usage. Premium suits comparison when substantial or uneven usage fits its five-day validity. Estimate photos, video and shared-device activity rather than choosing a tier to improve weak signal.

Set up in five steps

1. Confirm eSIM support and carrier unlocking for your exact device.
2. Install the emailed QR code over stable Wi-Fi before departure, following the order instructions.
3. In Switzerland, select AloOui for mobile data and enable roaming on that line as instructed. Validity begins on connection to a supported destination network.
4. Test a small webpage. Review home-line roaming separately and keep the eSIM installed if you need help.
5. Contact our support team in our Help Center.
