Cellesim, LLC · Delaware, USA
Data that crosses
every border.
We build travel connectivity. Our eSIM platform puts a working data plan on your phone in 178 countries before you land — no roaming bill, no plastic SIM, no counter at the airport.
What we build
One app from purchase to signal.
Most eSIM services stop at the sale. Ours carries the traveller all the way to a working connection, and stays there when something goes wrong.
Install in one tap
No QR photography, no settings menu. The profile installs from inside the app and the plan is live before you leave the terminal.
VPN built in
A native tunnel ships with the app, so the same connection that gets you online also reaches the services you use at home.
Priced in your currency
Rates refresh daily and checkout settles locally. The price you agreed to is the price on the statement.
The app
Built for the hour before the flight.
When there is no patience left for instructions, and the gate is already boarding.
Coverage
Countries, cities, and the routes between them.
Pick a single country, a single city, or a regional bundle that follows a whole itinerary across borders. Every plan shows its price before you tap it.
The company
A small team with a global footprint.
Cellesim, LLC is a Delaware limited liability company. We operate the Cellesim storefront, the iOS and Android apps, and the provisioning layer that connects them to carrier networks worldwide. Owning every part of that stack is why a coverage gap can be fixed the same day it is reported.
We publish in 31 languages because a traveller in Jakarta deserves the same clarity as one in Berlin.
