Croatia has solid coverage in Dubrovnik, Split, and along the Adriatic coast. Island hopping between Croatia's 1,000-plus islands is where coverage becomes more honest.

// What to expect
Coastal cities and resort towns
Dubrovnik, Split, Zadar, Rijeka, Rovinj, Pula, and the main tourist resort areas along the Adriatic coast all have reliable 4G coverage. The main Adriatic Highway has consistent signal. Major ferry terminals are generally well covered.
Islands and inland areas
Croatia has 1,244 islands of which 78 are inhabited. Coverage on the main tourist islands is reasonable in their main towns but thinner in coves. More remote islands like Vis and Lastovo have very limited coverage. Inland Slavonia is more variable.
💡 Island ferry crossings
Ferry crossings between Croatian islands can be entirely without signal. Download offline maps of every island you plan to visit before boarding your first ferry. Accommodation addresses and boat operator contacts should be saved offline.
// Practical tips
Emergency number: 112
Croatia uses 112 as the EU emergency number. Specialist numbers: 192 (police), 193 (fire), 194 (ambulance), 195 (sea rescue). Sea rescue is particularly relevant for sailors and kayakers on the Adriatic.
Jadrolinija ferries and booking
Jadrolinija is the main Croatian ferry operator. Book tickets in advance in July and August — car ferries on popular routes sell out. The Jadrolinija app handles booking with your eSIM active.
Dubrovnik and Plitvice require advance booking
Dubrovnik city walls and Plitvice Lakes require pre-booked entry during peak summer. Book online before arrival. Your eSIM data handles booking and real-time crowd information for the most popular sites.
// Travel security
Protect your connection in Croatia
