The short verdict
For Croatia, Hrvatski Telekom (HT) is the largest network and has the best coverage along the Dalmatian coast and on the islands — Hvar, Korčula, and Brač — where most summer travellers spend their time. Flysimio routes through HT and is the best value we found. A1 Croatia is a strong second, especially inland; Telemach is the budget domestic option. Airalo uses the same networks at close to double the price. Because Croatia joined the Schengen area and the euro in 2023, a regional Europe eSIM also covers it if you are visiting several countries.

Frequently asked questions
What is the best eSIM for Croatia?
Flysimio on the Hrvatski Telekom network is the best Croatia eSIM in 2026. HT has the widest coverage along the Dalmatian coast and islands, and Flysimio offers the lowest price. Airalo uses the same network but costs close to double.
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.
