Portugal eSIM FAQs
Your eSIM will activate automatically once you step off the plane in Portugal. We do suggest installing your Portugal Travel eSIM before departure (installation ≠ activation).
Installation is a breeze: scan the QR code provided or install via the ZenSim app over WiFi. Upon landing, the eSIM will activate itself.

Full Expense Control: Track data usage and spending in - app, so you avoid surprise fees.
Nope — the eSIM waits for you to land in Portugal before beginning data usage or counting plan days, unless of course you're already in Portugal then yes it will start using data immediately.

For any connection hiccups, check out our eSIM Troubleshooting Guide or get in touch.

If installed after arrival, it goes live right away.
