How Airalo works
You’ll need to create an account and download the Airalo app to install, activate, and use your eSIM, but we found the installation process quick and easy. The app allows you to check your eSIM data usage and expiration date, add data or days to your plan, and manage multiple eSIMS for multiple countries or trips. Your validity period starts once you connect to a local network so you won’t need to worry about setting it up too early.
