If you're visiting more than one place, our regional Travel eSIMs offer broader coverage so you can roam freely across multiple destinations.
Your eSIM will activate automatically once you step off the plane in Serbia. We do suggest installing your Serbia 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.

If you have trouble connecting, see our eSIM Troubleshooting Guide or message us for assistance.
Once you arrive in Serbia, your eSIM activates automatically if it’s already installed.
