The short verdict
For Croatia, Flysimio runs on Tele2 and A1 and was the best value we found — Airalo costs close to double. A1 has strong nationwide coverage, and Zagreb, Split, and Dubrovnik all have 5G, so most trips are well covered. For heavy island-hopping, Hrvatski Telekom (HT, part of Deutsche Telekom) has the deepest reach on the smaller Dalmatian islands like Hvar, Korčula, and Brač — and our 31-day Europe plans (10, 20, or 50 GB) connect to HT as well as A1 and Tele2, so choose one of those if hopping the smaller islands in peak summer is central to your trip. Because Croatia joined Schengen and the euro in 2023, a regional Europe eSIM also covers it if you're visiting several countries.

The Neum border trap — and how the Pelješac Bridge fixes it
Driving the classic Adriatic coastal road (the D8) from Split to Dubrovnik, you cross about 9 km of Bosnian territory at Neum — and the moment you do, a Croatia or EU-regional eSIM stops working, because Bosnia and Herzegovina sits outside the EU roaming zone. The fix, which many older guides still miss: since July 2022 the Pelješac Bridge bypasses Neum entirely, keeping you on Croatian networks the whole way to Dubrovnik. Take the bridge — it is free for cars — and you never leave coverage; take the old coastal road and you will drop out for that stretch.

Frequently asked questions
What is the best eSIM for Croatia?
Flysimio was the cheapest Croatia eSIM at 5 GB of the four providers we track when we checked in October 2026. Note that our Croatian plans route through Tele2 and A1, not Hrvatski Telekom — HT has the strongest coverage along the Dalmatian coast and on the islands, so pick on carrier rather than price if you are island-hopping. Airalo and Holafly both sell unlimited-only passes for Croatia, so the fixed-data comparison here is against Nomad.
Does an eSIM work on the Croatian islands?
Yes. Hrvatski Telekom has the best island coverage — Hvar, Korčula, Brač, and the other Dalmatian islands all have 4G. It is the safest choice if you are island-hopping in summer.
Can I use a Europe eSIM in Croatia?
Yes. Croatia joined the Schengen area and the euro in 2023, and it is included in Flysimio's Europe regional plan. If your trip spans several European countries, the regional plan is convenient; for Croatia alone, a country-specific eSIM is cheaper per GB.
Is there coverage at Plitvice Lakes?
Yes, at the entrances and main boardwalks on Hrvatski Telekom and A1. Signal can thin deeper inside the park among the waterfalls, so download your map and tickets in advance.
Do I need a Croatian SIM card or can I use an eSIM?
An eSIM is the better choice for most visitors — cheaper than kiosks, installed before you land, and your home number stays active. A physical SIM is only needed if your phone does not support eSIM.
