Contact us
Something not adding up with a plan, an install or an order? Email us. A person on the other end reads it — no automated phone menu stands in the way.
Send it in whichever of this site's languages you're most comfortable with — French, German, Italian or otherwise — and the reply comes back in that same one.
Response time
We reply within one business day and usually much sooner. We work on Central European hours — the same clock as Switzerland — so a question sent during your trip is normally answered the same day.
Faster in the app
Once the eSIM is running, send your message from inside the app rather than by email — it carries your plan details along automatically, so we are not asking you to repeat them.
