About TraveleSIM
Connection should be the easiest part of arrival.
Travel rarely goes blank — except in the ten minutes after you land. The bewildered scroll for free wifi. The airport SIM-card kiosk with the eight-page activation form. The roaming bill that shows up two weeks later and ruins the Tuesday it lands on. We built TraveleSIM to make those ten minutes disappear.
Why we built this
One too many CHF 200 phone bills.
Every traveler we know has a version of the same story. A short trip, a forgotten setting, a notification that says "data roaming activated," and a few weeks later, an invoice that buys an entire other vacation. Or the queue at a foreign-airport counter at midnight, with a clerk who only speaks the local language and a SIM tray that won't open without a paperclip.
Travel data has been a tax on traveling — collected by carriers who built decades of lock-in into something that should cost a coffee. We think you should pay the same as a local, install in seconds, and walk out of the jet bridge already online. So we made that.
How we keep it stupidly simple.
The price you see is the price
One CHF amount, paid once. No auto-renewals, no hidden fees, no surprise bills at 3am in Bangkok because something switched to roaming while you slept.
One tap, on the phone you already carry
No SIM swap, no spare phone, no second device. Install before takeoff or in the Uber to the airport — your data is waiting at the gate.
Made by people who travel
Not enterprise software designed for a cubicle. We've been the person at 2am with a dead phone and an Uber to catch. We built the service we wished existed.
The team
Small, focused, obsessive.
We're a small team in the United States. We answer our own emails. We watch the support inbox the way most people watch their family group chat. We will probably reply to your message before this paragraph finishes loading on your phone.
That intimacy is the point. We're not trying to be the biggest eSIM provider; we're trying to be the one that gets the few seconds between landing and getting online exactly right — and then keeps doing that, for as many people, in as many countries, as we can reach. If something feels off, tell us. We'll fix it. That promise costs us nothing because we mean it.
