How do you get a mobile phone plan in Croatia in 2026?

Buy a prepaid SIM or tourist eSIM from A1, Hrvatski Telekom (T-HT), or Telemach at Zagreb or Split airport kiosks, Tisak newsstands, petrol stations, or operator stores. Passport identification usually works for basic prepaid registration. Bring an unlocked phone; carrier-locked handsets stall the first hour. Top up with cash or card and test data on your actual street before you celebrate coverage maps: Living in Zagreb and Living in Split.

MVNOs such as Bonbon or Tomato can stretch data budgets once you understand top-up apps. Tourist weekly packs suit scouting trips; they are not the cheapest long-stay product. Keep the packaging and activation SMS so you can prove the number when banks ask.

Postpaid plans usually want an OIB, passport or residence card, and a Croatian address trail: Get an OIB, Register address, and Apply for a residence permit. Contract rates often undercut perpetual tourist packs for heavy data users. Use the local number for bank OTPs after you open an IBAN: Open a bank account.

Island and coastal signal can wobble outside town centres even when Zagreb fibre feels solid: Utilities, internet, and transport. Treat mobile data as video-call backup when home Wi-Fi drops. Budget the line inside Monthly budget rather than as a forgotten roaming surprise: How expensive is Croatia.
