Where are you heading?

Search for the country above or pick it from the directory. onesim sells regional packages, so each destination page shows the package that covers it along with its data options and validity before you buy.

Choose a regional package whose coverage list includes every stop on your route. One eSIM and one package then work across all of them — no switching between countries. Open Coverage on any package to see the full country list. Explore regional packages

Most phones from 2019 on support eSIM, and the phone needs to be carrier-unlocked. The quickest way to be sure is to check your model in the compatibility guide before you buy. Check compatibility

Installing the eSIM does not start the clock. Your package starts the first time the eSIM connects to a network in a country it covers, even while mobile data is off. Install at home over Wi-Fi and keep the onesim line switched off until you arrive; if your home country is covered too, the package would start the moment the line connects there.
