How Does SIM Card & Internet Work in Croatia?
Last verified: 2025-06 · Europe
1The Quick Answer
Hrvatski Telekom has the best coverage including on the islands; EU residents can roam for free on their home SIM.
2What You Need to Know
Croatia's three main mobile operators are Hrvatski Telekom (HT, best overall coverage), A1 Croatia, and Telemach. SIM cards are available at airports, phone shops, and some supermarkets. EU residents can use their home SIM under EU roaming rules at no extra cost — check your data allowance before travelling. Coverage is excellent in coastal cities and on the main islands but can be patchy on smaller or more remote islands and in the Dinaric inland areas. Airalo eSIM works well in Croatia for non-EU travellers. Free Wi-Fi is widely available in cafes, restaurants, hotels, and public spaces.
