About OneSim
Land, switch on, you're online.
We help travellers stay connected abroad without the roaming bill. One eSIM, bought in minutes, ready the moment you arrive.
Our story
Roaming shouldn't be the most expensive part of the trip.
Most of us know the feeling: you land, turn on your phone and get a text about daily roaming charges. Or you spend your first hour abroad hunting for a SIM card kiosk, a passport photocopy and a paperclip.
OneSim exists to remove that friction. We sell prepaid travel data plans as eSIMs, so there is nothing to collect and nothing to swap. You choose your destination, pay once, install the eSIM before you fly and it connects to a local network when you arrive.
Our plans run on a global eSIM network partner with agreements with mobile networks around the world. That lets us offer local data plans in 160 countries and a single Global plan for trips that cross many borders, all from one simple store in English and Hebrew.
