Croatia is easy to stay connected in — strong coverage on the coast, on the islands and in the national parks' visitor areas. But there is one trap almost every road-tripper drives into: the coast road between Split and Dubrovnik passes through Neum, a short stretch of Bosnia and Herzegovina, which is outside the EU.
Short answer: a Croatia plan or an EU-covering Europe bundle works for most trips. If you drive to Dubrovnik on the coast road or visit Mostar or Montenegro, check that your plan covers those countries — or set your phone to stay on its Croatian network.
What a Croatia eSIM costs
At the time of writing (October 2026), Wanderly's Croatia plans start at $2.99 for 1GB, with 10GB for 30 days around $8. The median across data-only Croatia plans is about $0.80 per GB — well under the $1.43 median across 187 countries in the Wanderly eSIM Price Index.
The Neum problem
Croatia joined the EU in 2013, so EU phone plans roam there at domestic rates. Bosnia and Herzegovina, Montenegro and Serbia are not in the EU.
- Driving Split → Dubrovnik on the coast road (the D8) crosses about 9 km of Bosnian territory at Neum. Phones often switch to a Bosnian network automatically — which can trigger expensive non-EU roaming on a home plan, or lose service on a Croatia-only eSIM.
- The Pelješac Bridge (opened 2022) lets you bypass Neum entirely on the way to Dubrovnik. Many drivers now take it.
- Day trips to Mostar or Kotor take you out of Croatia altogether.
What to do: take the Pelješac Bridge route, or turn off data roaming on your home line before Neum, or buy a plan that lists Bosnia and Herzegovina and Montenegro.
Networks and coverage
Croatia's networks are Hrvatski Telekom, A1 and Telemach. Travel eSIMs connect to a partner network automatically.
- Zagreb, Split, Dubrovnik, Zadar, Pula: strong 4G and widespread 5G.
- Islands (Hvar, Brač, Korčula, Vis): good in towns and harbours; weaker in remote coves.
- Ferries and catamarans: coverage near the coast, drops mid-channel.
- Plitvice and Krka national parks: good at entrances and main paths; patchy in the lower canyons.

FAQ
Does my phone roam in Bosnia when driving to Dubrovnik? It can. The coast road passes through Neum in Bosnia and Herzegovina, outside the EU. Use the Pelješac Bridge route or check that your plan covers Bosnia.
How much does an eSIM for Croatia cost? Wanderly Croatia plans start at $2.99 for 1GB, with a median of about $0.80 per GB.
Is there coverage on the Croatian islands? Yes, in towns and harbours. Remote coves and mid-channel ferry crossings can lose signal.
Does a Croatia eSIM work in Montenegro? Only if the plan lists Montenegro. Check before a day trip to Kotor or Budva.
Does an EU phone plan work in Croatia? Yes — Croatia is in the EU, so EU roaming rules apply, subject to fair use.
Heading further down the coast? Albania is outside EU roaming — see the best eSIM for Albania.
