Traveller's guide
Staying connected in Interlaken
A weak connection does not just feel slow — it wastes your plan. Pages half-load and reload, uploads restart, apps retry in the background. Sitting on a solid network is part of what makes a fixed plan last the whole trip.
In Interlaken the biggest single draw is the mountain railway bookings and weather checks that decide each day. Download the offline map before you fly and let the eSIM handle live traffic only.
The Jungfraujoch is expensive and pointless in cloud, so visitors check the summit webcam before committing — a decision made on a phone at breakfast.

FAQ
Questions, answered
Will the Interlaken eSIM work on my phone?
Any eSIM-capable, carrier-unlocked handset — iPhone XS and newer, Samsung Galaxy S20 and newer, Pixel 3 and newer. Dial *#06#; an EID number means yes.
How fast is the data in Interlaken?
4G and 5G where the local network provides it. Speed varies by area and time of day, as it does for everyone on the same network.
Do I need a passport or registration?
No. That requirement applies to physical SIM cards bought locally, not to this eSIM.
When does my plan start?
On the first connection to a local network — when you switch off flight mode at ZRH / BRN. Not when you pay.
What happens when my data runs out?
Your connection simply pauses — no surprise bills, ever. To keep going, buy another package for the same destination. If that happens often, the unlimited plan is the cheaper answer.
Can I add data to an eSIM I already have?
Not on a data package — the amount of data is fixed, so nothing is added to an eSIM that is already running. If you need more, another package for the same destination arrives by email and installs alongside the eSIM you already have. Our unlimited plans work differently: those can be extended by extra days while they are still active.
Can I keep my normal number for calls and texts?
Yes. Keep the home line active for SMS codes with its data off, and let the eSIM carry the data.
Can I use it as a mobile hotspot in Interlaken?
Yes. Bear in mind a second device draws from the same plan.
Does it work outside Interlaken?
Yes — it is a Switzerland-wide plan.
Staying longer than a week?
Unlimited is billed per day and the daily rate falls the longer you stay — same networks, no counting.
