Frequently Asked Questions

Q: Does Croatia eSIM work on all islands?

Q: Will I have signal on ferries?

A: Short crossings usually maintain signal. Longer routes (like Split to Vis or Dubrovnik) may lose signal mid-crossing but reconnect near islands. Ports have excellent coverage for booking connections. Download entertainment for longer crossings.

Q: Is Plitvice Lakes covered?

A: Yes, Plitvice Lakes National Park has good coverage at entrances, facilities, and along main boardwalk trails. Some deeper forest areas may have weaker signals, but coverage is sufficient for navigation and sharing photos of those stunning waterfalls.

Q: Does Croatia use the Euro now?

A: Yes, Croatia adopted the Euro in January 2023. The Croatian Kuna is no longer used. This makes travel easier, especially when combining Croatia with other Eurozone countries.

Q: What about day trips to Montenegro?

A: Montenegro is NOT in the EU. If you're doing day trips to Kotor or the Bay of Kotor from Dubrovnik, check if your eSIM includes Montenegro. Some Europe plans don't. You may need a plan that explicitly covers both or accept no data in Montenegro for a day trip.

Q: Is 5G available in Croatia?

A: 5G is available in Zagreb and expanding to Split, Dubrovnik, and other cities. Coastal and island areas primarily use 4G, which provides good speeds of 20-50 Mbps—plenty for navigation, social media, and video calls.
