EuropeZagrebCroatia eSIM and Travel Guide: Stay Connected on the Adriatic Coast and Islands
Croatia has three main mobile operators, with Hrvatski Telekom delivering the strongest 4G and 5G coverage including the Dalmatian islands, and A1 offering a strong alternative along the Adriatic coast. A Roamix Croatia eSIM connects to the best local network on arrival at Zagreb or Split Airport without a SIM kiosk visit. Budget 3 to 5 GB for a two-week summer trip, download offline maps for island hops and national parks, and note that EU Roam Like At Home means EU SIM holders pay no extra. Croatia uses the euro since January 2023.
Key Takeaways
- Hrvatski Telekom has the strongest and most widespread 4G and 5G coverage in Croatia, including the Dalmatian islands.
- A Roamix eSIM activates automatically on arrival at ZAG or SPU and avoids the airport SIM kiosk queue.
- Croatia adopted the euro in January 2023, simplifying budgeting for European visitors.
- EU Roam Like At Home applies to EU SIMs, but a Roamix Croatia eSIM gives non-EU travellers equally competitive data rates.
- Download offline maps for Plitvice Lakes, Kornati National Park and any island ferry routes before leaving the mainland.

Notes
RecommendedRoamix eSIM
Most travellers, especially island hoppers
Instant activation on HT or A1, no airport kiosk queue, no roaming bill and consistent coverage across islands and national parks.
EU Roam Like At Home SIM
EU SIM holders already in Europe
If you have an EU SIM with Roam Like At Home, it works in Croatia at no extra charge. Non-EU travellers do not benefit from this.
Local physical SIM
Long stays needing a Croatian number
HT and A1 SIM cards available at Tisak kiosks in airports and city centres. Requires passport.
Carrier roaming
Very short trips or emergencies
International carrier roaming in Croatia is expensive outside EU Roam Like At Home. A Roamix eSIM covers a two-week trip at a fraction of the cost.
For most visitors to Croatia, a Roamix eSIM is the most practical and cost-effective choice, delivering HT network coverage from the moment you land at Zagreb or Split Airport and following you seamlessly across the islands.

Get your Croatia eSIMMobile Networks in Croatia
Croatia has a well-developed mobile network anchored by three operators: Hrvatski Telekom (the coverage leader, a Deutsche Telekom subsidiary), A1 Croatia (strong along the Adriatic coast and in main cities), and Telemach (formerly Tele2, solid in urban areas). Hrvatski Telekom delivers the most extensive coverage including the ferry-connected Dalmatian and Kvarner islands. A Roamix Croatia eSIM connects to the best available local network on arrival, giving non-EU travellers competitive data rates comparable to EU Roam Like At Home benefits.
Market leader and coverage champion, with the strongest 4G and 5G network across mainland Croatia and the most extensive coverage on the Dalmatian and Kvarner islands. Best choice for any island-hopping itinerary.
Strong competitor with 5G in Zagreb, Split, Rijeka and Zadar. A1 has excellent coverage along the Adriatic coastal highway and in all major tourist hubs including Dubrovnik, Hvar, Brac and Korcula.
Third operator with solid 4G in Zagreb and major cities. Coverage is less extensive than HT or A1 on the islands and in rural areas. Good value for urban-focused trips.
Typical Speeds
5G in Zagreb, Split, Rijeka and Zadar delivers 20 to 80 Mbps. 4G LTE along the Adriatic coast and on main islands delivers 10 to 30 Mbps. Ferry crossings and more remote islands occasionally drop to 3G.
5G Status
5G is available in Zagreb, Split, Rijeka and Zadar via Hrvatski Telekom and A1. Coverage is expanding along the Adriatic coast and to major tourist areas. The national parks and rural interior are 4G or 3G only.
Hrvatski Telekom consistently outperforms on the islands, which is the defining factor for most Croatia trips. A1 is a reliable alternative in cities and coastal towns. For any island-heavy itinerary, HT-connected eSIM is the strongest choice.
Remote national park interiors such as Plitvice Lakes, Paklenica and Krka have reduced coverage or dead spots in gorge sections. Small offshore islands far from the coast may have limited 4G. Ferry crossings between outer islands can drop to 3G. Always download offline maps before island hops.
Croatian operators use LTE bands 3 (1800 MHz), 7 (2600 MHz) and 20 (800 MHz) for coverage and capacity. 5G runs on n78 (3.5 GHz) in urban areas. Standard 4G and 5G phones work without configuration.
Data Usage Guide
Data needs in Croatia are moderate to light. The main towns and cities have strong 4G and 5G. Island hopping benefits from pre-downloaded offline content and the ability to check ferry schedules in real time.
Download offline map packages for any national parks and outer islands before leaving Split or Zadar, where 5G speeds make large downloads fast.

Frequently Asked Questions
Croatia eSIM, connectivity, and travel
What is the best eSIM for Croatia?
Roamix is a top choice for Croatia because it connects to Hrvatski Telekom, the network with the widest 4G and 5G coverage including the Dalmatian islands. You activate before flying and land already connected at Zagreb or Split Airport.
Do I need a SIM card for Croatia?
You do not need a physical SIM. A Roamix Croatia eSIM gives you local 4G and 5G on arrival without passport registration, at a fraction of home-carrier roaming costs.
Which mobile network is best in Croatia?
Hrvatski Telekom (HT) leads on coverage and speed, particularly on the Dalmatian and Kvarner islands. A1 is a strong alternative in cities and along the coast. A Roamix eSIM connects to whichever is strongest at your location.
Does Croatia have 5G?
Yes. HT and A1 both offer 5G in Zagreb, Split, Rijeka and Zadar, with coverage expanding to major tourist areas. National parks and most islands are 4G only.
How do I set up an eSIM for Croatia?
Buy a Roamix Croatia plan online, install the eSIM via QR code over wifi before you fly, then enable data roaming on the Roamix line. It connects automatically to HT or A1 when you land.
Does the EU Roam Like At Home apply in Croatia?
Yes. Croatia is an EU member state. EU SIM holders can use their home plan with no extra roaming charges. Non-EU travellers, including those from the US, UK, Canada and Australia, do not benefit from this and should use a Roamix eSIM for competitive data rates.
Will my eSIM work on Croatia's islands?
Yes. Hrvatski Telekom has the most extensive coverage on the Dalmatian and Kvarner islands. Ferry crossings to outer islands may have brief 3G stretches. Download offline maps before island hops for reliable navigation without signal.
What currency does Croatia use?
Croatia adopted the euro in January 2023. Cards are widely accepted in tourist areas. Carry some cash for smaller island towns and rural markets.
Do I need a visa for Croatia?
Croatia is in the Schengen Area. EU and EEA citizens enter freely. US, Canadian, Australian and UK citizens can visit visa-free for up to 90 days. Check current Schengen rules for your nationality before travelling.
How much data do I need for two weeks in Croatia?
3 to 5 GB is sufficient for most trips. Download offline map packages for Plitvice Lakes and any islands you plan to visit before leaving Split or Zadar, where fast 5G makes large downloads quick.
Is airport wifi at ZAG or SPU enough, or should I get a Croatia eSIM?
Free wifi is available at Zagreb and Split airports, but it is only useful while you are in the terminal. A Roamix Croatia eSIM gives you mobile data from the moment you land to check ferry schedules, book taxis and navigate to your accommodation.
What is the best time to visit Croatia?
June and September offer warm weather, open island services and fewer crowds than peak July and August. December is excellent for Zagreb's Advent Christmas market. May is ideal for Plitvice Lakes and cycling in Istria.
Is Croatia safe for tourists?
Croatia is one of the safest countries in Europe. Petty theft can occur in busy Old Town areas of Dubrovnik and Split in peak summer. Keep Roamix data active for navigation and emergency services on 112.
Can I use rideshare apps like Bolt and Uber in Croatia?
Bolt and Uber operate in Zagreb and Split. Both require an active data connection. Use Roamix data to book rides directly from Zagreb or Split airport.
