Croatia eSIM: mobile data on the coast, islands and ferries
How to get mobile data in Croatia: coverage in Zagreb, Split and Dubrovnik, on the islands and ferries, the Neum stretch on the way to Dubrovnik, local SIM vs eSIM, and Europe plans.
Plan for your trip: Croatia · Data for your trip — See plans →
The easiest ways to get mobile data in Croatia are a travel eSIM installed at home or a local SIM from a phone shop. In Zagreb, Split, Zadar and Dubrovnik, the mobile network is solid; the quirks start on the islands, on ferries and in the mountains behind the coast. Croatia is in the EU, but on the way to Dubrovnik, or on a trip to Montenegro, your phone may connect to a network in a non-EU country.
How does mobile data work in Zagreb, Split and Dubrovnik?
Mobile data in Croatian cities covers the centers, waterfronts, ports and airports of Zagreb, Split, Zadar and Dubrovnik. Croatia’s major carriers, Hrvatski Telekom, A1 and Telemach, run 4G and 5G networks, and a travel eSIM connects to one of them as a partner network. Which network you get depends on the plan and your phone model.
In summer the Croatian coast gets huge crowds, and in the old towns of Split and Dubrovnik, on the waterfronts and in the ports, the network can get congested. Data is slower then, but usually still fine for maps, messaging and ride-hailing. Inside the thick stone walls of an old town, the signal can be weaker than out on the street.
Is there signal on the Croatian islands and ferries?
Coverage on the Croatian islands is good in towns and resorts and weaker inland and in secluded coves. On ferries and catamarans, the signal holds near the shore and may drop on open water between islands. That’s the main thing to plan for on an island-hopping trip.
| Where | What to expect | What to do in advance |
|---|---|---|
| Split, Zadar, Dubrovnik | Solid coverage, congestion possible in high season | Nothing special |
| Hvar, Brač, Korčula, Krk | Available in towns, weaker in coves and inland | Booking and host contacts saved offline |
| Small islands and yacht anchorages | Uneven signal with gaps | Don’t count on signal all day |
| Ferries and catamarans | Available near the shore, weaker on open water | Screenshots of tickets and timetables |
| Plitvice Lakes, Krka | Available at the entrances and in villages, weaker in places on trails | An offline map of the park |
| Velebit and Biokovo mountains | Signal drops on hiking routes | Route track, emergency number 112, weather forecast |
Neum and the road to Dubrovnik: why your phone switches countries
The coastal road from Split to Dubrovnik has historically run through Neum, a short stretch of coast that belongs to Bosnia and Herzegovina. Bosnia and Herzegovina is not in the EU, and as of October 2026 EU “roam like at home” rules don’t apply there. The Pelješac Bridge, open since 2022, lets you bypass Neum, but buses and cars may still take the old road across the border.
If your phone picks up a Bosnian network on the way and your plan doesn’t cover Bosnia and Herzegovina, you’ll lose data for that stretch, and on a local Croatian SIM, roaming may kick in on the carrier’s terms. Check whether Bosnia and Herzegovina is on your plan’s country list, or just wait out the stretch and avoid heavy apps.
Local SIM card or eSIM in Croatia?
Local SIM cards in Croatia are sold at carrier stores, kiosks and gas stations. Reports on prepaid registration vary: travelers say carrier stores may ask for a passport, while kiosks often sell cards without one. Check the current process when you buy. A Croatian number is useful for a long stay or a seasonal rental.
A travel eSIM saves you the trip to the store. With MoreSim, you buy on the website or in the Telegram bot @moresim_bot, paying with Telegram Stars from any country, right in the bot (bank card and SBP payments currently work with cards issued in Russia), and the QR code arrives in the chat in about 30 seconds. The profile works as a second line, and your home SIM stays in the phone. MoreSim plans are mobile data only, with no phone number: you call through messaging apps, and bank texts still reach your home SIM. Data amounts and validity for Croatia are listed on its catalog page.
- Check in the bot whether your phone supports eSIM.
- List the countries on your route: Croatia, plus Montenegro or Bosnia if you’re heading there.
- Buy a plan and install the profile at home over Wi-Fi.
- After landing, pick the eSIM for mobile data and turn on data roaming on it: most travel eSIMs run on a local carrier’s network as roaming. If your plan’s instructions say otherwise, follow them.
- Turn off mobile data on your home SIM so your data doesn’t go through your home carrier. Keep the line itself on if you’re expecting texts from your bank.
Is Croatia covered by a Europe eSIM plan, and what about next stops?
Croatia is an EU member, and European regional plans usually include it. Check the exact country list for the MoreSim Europe plan on the plan card in the catalog or in the bot. Check Montenegro, Bosnia and Herzegovina and Serbia separately: they’re not in the EU and may not be included in European plans.
| Route | Countries to check in your plan |
|---|---|
| Split to Dubrovnik | Croatia, plus Bosnia and Herzegovina if you take the old road |
| Dubrovnik to Kotor | Croatia, Montenegro |
| Zagreb to Budapest or Ljubljana | Croatia, plus Hungary or Slovenia |
| Split to Ancona by ferry | Croatia, Italy; there may be no signal on the open sea |
There are no trains along the Croatian coast, so people usually travel between towns and to neighboring countries by bus and ferry. Trains link Zagreb with Budapest and Ljubljana; check the current timetable before your trip.
How much data do you need in Croatia?
For a beach holiday and trips along the coast, you won’t need much data: maps, messaging, ferry timetables and ride-hailing. Usage climbs with video, stories from yachts and beaches, and video calls. If you’re renting an apartment without good Wi-Fi and working remotely, plan for more.
- Download offline maps of the coast and the islands.
- Keep photo and video uploads to the cloud on Wi-Fi only.
- Turn off automatic app updates over mobile data.
- If you run out, top up without a new eSIM: use “Top up data” on the eSIM card in your account or in the bot’s app, if top-ups are available for that plan.
For a detailed estimate, see our guide on how much data you need for travel. If your data won’t connect, MoreSim support is reachable via /support in the bot, a ticket in your account and email.
FAQ
Is there mobile internet on the Croatian islands?
On the larger Croatian islands, Hvar, Brač, Korčula, Krk and Rab, mobile data usually works in the towns and resort villages. Inland, in secluded coves and on small islets, the signal is weaker and can drop. In high season, the network in popular spots can get congested.
Is there internet on ferries in Croatia?
On ferries and catamarans along the Croatian coast, the signal usually holds near the shore and weakens on open water between islands. Save your tickets, the timetable and your island accommodation booking offline before boarding. Once you reach port, data comes back.
Why does my phone connect to another country on the way to Dubrovnik?
The coastal road from Split to Dubrovnik has historically run through Neum, a stretch of coast belonging to Bosnia and Herzegovina, which is not in the EU. The Pelješac Bridge, open since 2022, lets you bypass Neum, but buses and cars may still take the old road. If your phone picks up a Bosnian network and your plan doesn’t cover Bosnia, you’ll lose data for that stretch.
Do I need a passport to buy a SIM card in Croatia?
Reports vary: travelers say carrier stores may ask for a passport, while kiosks often sell prepaid cards without one. Check the current process before your trip and when you buy. A travel eSIM is installed at home and needs no local registration.
Is Croatia included in Europe eSIM plans?
Croatia is an EU member and is usually included in European regional plans, but every plan has its own country list. Check Croatia and the other countries on your route on the Europe plan card on the MoreSim catalog page or in the bot @moresim_bot. Check Montenegro and Bosnia and Herzegovina separately, since they are not in the EU.
Which eSIM do I need for Croatia and Montenegro?
You need a plan that covers both countries, or two separate plans as two profiles. Croatia is in the EU and Montenegro isn’t, so check the country list on the plan card to see if one regional plan covers both. If Montenegro isn’t included, install a separate plan for it at home and switch your mobile data line after the border.
