eSIM for Croatia

Data for Dubrovnik, Split, the islands and Zagreb, installed before you land. Croatia is on the Europe plan and on the Balkans plan, so a coast road trip that dips into Bosnia or Montenegro stays on one eSIM.

Good to know

What's included, when it starts, and how to get connected.

Included countries
The Croatia plan covers Croatia only.
Local networks
In Croatia your eSIM connects to A1 and Telemach — 4G/5G where the network offers it.
When validity starts
Your package starts when your phone first connects to a network at the destination — not when you install it. Crossing a border does not restart it.
Installation and activation
Install the eSIM while you still have internet — at home or on Wi-Fi. Installation does not start validity. If you already have a onesim eSIM installed, a new package is added to it — no second installation. Setup guide
Calls and texts
onesim is data-only. Calls and messages work over data in apps like WhatsApp or FaceTime; your usual SIM keeps your number.
Support and refunds
Message the onesim support team from the app or the website. If a package cannot be installed or used, the refund policy explains what applies. Refund policy
Travel notes

Practical things, honestly.

Getting around

The islands run on ferry timetables, and the timetables change with the season.

Jadrolinija car ferries and the faster catamarans (Krilo, TP Line) link Split with Brač, Hvar, Vis and Korčula; in summer there are several a day, in winter sometimes one. Catamaran seats sell out in July and August — book online a few days ahead. A car on a ferry needs to queue early; a foot passenger with a bag does not.

Driving

The coast road is beautiful and slow; the motorway is neither.

The A1 motorway runs inland from Zagreb to Split and on towards Dubrovnik with tolls paid at booths (card is fine). The old Adriatic Highway (D8) hugs the coast, takes twice as long and is the reason you came. Since the Pelješac bridge opened in 2022 the drive to Dubrovnik no longer crosses into Bosnia at Neum, though the detour to Mostar is worth making on purpose.

Money

Euros since 2023, and Schengen too.

Croatia adopted the euro and joined the Schengen area in January 2023, so there is no currency to change and no passport control from Slovenia, Hungary or Italy. Cards are accepted almost everywhere; small konobas on the islands sometimes still prefer cash. A tourist tax of a few euros a night is charged on top of the room.

When to come

Dubrovnik in July is a cruise-ship crowd; in October it is a city.

The walls, Plitvice and the Split waterfront are at capacity from mid-June to early September. May, June, September and early October have the same light with half the people, and the sea stays swimmable into October. Plitvice needs a timed ticket in high season — book it before you drive there.

Small things

The sea is clearer than the guidebooks say, and the beaches are stone.

Pebbles and rock, almost everywhere — water shoes are the single most useful thing in the bag. Tap water is safe to drink throughout the country.

Coverage

Two packages cover it, and the Balkans one keeps going south.

Croatia is on the Europe plan and on the Balkans plan. For a trip that stays on the coast, either works; the difference is what happens when the road leaves the country. The Europe plan carries on into Slovenia, Italy, Austria and Hungary. The Balkans plan carries on into Bosnia and Herzegovina, Montenegro, Serbia, North Macedonia, Albania and Kosovo — the Dubrovnik–Kotor–Mostar triangle most road trips end up drawing.

Coverage follows the local networks: strong along the whole coast and on the ferry routes, good on the motorway, and thinner on the island interiors and in the mountains behind the coast, as it is for everyone.

Reading about Croatia

Croatia questions.

Answers about data, coverage and setup for Croatia.

Yes. Hvar, Brač, Korčula, Vis and the rest are Croatia and use the same networks as the mainland, and the ferries stay in range of the coast for most of the crossing. Coverage thins on the island interiors and the walking trails, so download an offline map of an island before you set off across it.
