Best SIM and eSIM for Croatia: data plans, Wi-Fi and phone tips

Pick by how long you stay, which passport you hold and whether you need a Croatian number for calls or bookings. The table below is the short version; the steps after it explain how to set each one up.

An eSIM is a digital SIM profile you download to your phone. You buy it online, scan a QR code or tap a link, and it activates when you land in Croatia. Nothing to collect, no queue at the airport, no passport check. Most recent iPhones, Samsung Galaxy phones and Google Pixels support eSIM; older or some budget models do not. Check your phone's settings before you buy.

Prices vary by provider and by how much data you want. As a rule, a Croatia-only plan for a week costs less than a regional Europe plan, but a Europe-wide plan is worth the small premium if you also cross into Slovenia, Montenegro or Bosnia and Herzegovina. Buy from a provider that names the Croatian network it uses, and check whether the plan is data-only or includes calls.

Install the eSIM at home on Wi-Fi, not at the airport. Keep your home SIM active for bank codes and two-factor messages, and set the eSIM as your data line. If the eSIM does not connect on landing, toggle airplane mode once, then check that data roaming is on for that line.

Croatia's three main operators are Hrvatski Telekom, A1 and Telemach. All sell prepaid SIMs, and all three have good coverage along the coast and on most islands. Expect gaps in the Lika mountains and in the interior of some islands, where signal can drop for long stretches.

Buy at a Tisak kiosk or an operator shop. You need photo ID — a passport is fine — and the SIM is registered to you, which is standard across the EU. Airport shops are convenient but often carry a narrower range of bundles; a town-centre shop usually has more choice and staff who will set the SIM up for you.

Top-ups are sold at kiosks, supermarkets and operator shops, and by card through the operator's app. If you stay a month or more, a prepaid bundle renewed monthly is usually cheaper than an eSIM. If you only need a Croatian number for calls and bookings, a small prepaid plan plus your eSIM for data is a workable split.

If your SIM is from an EU or EEA country, you roam in Croatia at your home prices under the EU roam-like-at-home rules. That covers calls, texts and your normal data allowance. Nothing to buy, nothing to register. Fair-use limits apply if you roam for months rather than weeks, and a few budget operators cap data abroad, so check your plan before you rely on it.

Visitors from the US, UK, Canada, Australia, New Zealand and Ireland should assume roaming charges. UK SIMs lost EU roaming with most operators after Brexit, and US and Australian plans usually charge a daily fee or a high per-MB rate. For a short trip an eSIM is usually cheaper than a roaming pass; for a long stay a local prepaid SIM wins.

Croatia uses +385 as its country code, and mobile numbers start 09x. Dial the full international format from a foreign SIM. WhatsApp and Viber are both widely used, and apartment hosts often message on WhatsApp, so you rarely need a local voice number for everyday contact.

Free Wi-Fi is common in apartments, hotels, cafés and many old-town squares, and it is usually fast enough for maps, messaging and email. It is less reliable on ferries, on remote beaches and in the interior. Treat Wi-Fi as a supplement, not your main connection, if you are moving between islands.

Mobile coverage is good along the coast and on most islands, which covers the usual Split–Hvar–Dubrovnik route. Expect gaps in the Lika mountains, in some island interiors and on a few rural roads. If you plan to hike or sail, download offline maps before you leave the coast.

Two practical notes. First, keep a screenshot of your accommodation address and host's phone number in case you arrive without signal. Second, if you rely on your phone for ferry tickets or bus bookings, save them offline too — the Jadrolinija and Arriva apps both work better with a connection, but a saved PDF does not need one.

Do the phone work before you leave home, where you have stable Wi-Fi and can reach your provider's support. The order below avoids the usual arrival-day problems.

Airport SIM shops are convenient but can be pricier and carry fewer bundle options than a town shop. If your flight lands late, an eSIM you installed at home avoids the problem entirely.

Some phones sold in the US and Canada are carrier-locked even when paid off; check before you buy an eSIM. Dual-SIM phones handle a home SIM plus a Croatian eSIM well, but battery life drops when both are active.

On the coast in July and August, networks get busy in Dubrovnik, Hvar and Split old towns, and speeds can drop in the evening. It is rarely a problem for maps and messages, but do not plan to work from a crowded old-town square.

If you are travelling on to Slovenia, Montenegro or Bosnia and Herzegovina, check whether your plan covers those countries. A Croatia-only eSIM will not, and Bosnia and Herzegovina is outside the EU roaming zone.
