    What is Airalo?

    Airalo is the largest global marketplace for eSIM cards. Instead of hunting for a local SIM card at the airport, you can buy a data package for 200+ countries in the app in a few minutes and activate it by scanning a QR code.

    Why I use it

    When I arrive in a new country, I don't want to deal with SIM card shops or expensive roaming from my Czech operator. I install Airalo at home on Wi-Fi, choose a package, and immediately have data upon arrival - no queues, no paperwork.

    How it works

    1. Download the Airalo app (iOS/Android)
    2. Select a country or regional package (e.g., Eurolink for Europe)
    3. Pay by card or Apple/Google Pay
    4. Scan the QR code and activate the eSIM in your phone settings
    5. Upon arrival, turn on data roaming on your new eSIM and you're good to go

    Who is it ideal for

    • Travelers across multiple countries - regional packages cover an entire continent
    • Short trips (3-14 days) - cheaper than Czech roaming, no commitments
    • Digital nomads - combine with a local SIM card for longer stays
    • People who don't want to bother - everything from the app, no plastic

    Usage tips

    • Buy eSIM at home on Wi-Fi - installation abroad on expensive data is painful
    • Regional packages (Eurolink, Asialink) are more advantageous than multiple country packages if you're traveling to several countries
    • Verify that your phone supports eSIM (iPhone XS+, most flagship Androids from 2020)
    • Most packages are data-only - for calls, use WhatsApp, Signal, or iMessage

    My verdict

    Airalo is my number one for mobile data abroad. In Japan, I paid ~$22 for 8 GB / 30 days instead of thousands for roaming. Install at home, activate upon arrival, and have peace of mind.
