It depends. Croatia is in the European Union (EU), so "Roam Like at Home" applies for EU citizens. However, since Brexit, many UK providers (like O2, Vodafone UK, Three) have reintroduced roaming fees for Croatia. For travelers from the USA, Turkey, or Asia, roaming is definitely not free and is very expensive. A Cellesim eSIM is the safest way to get guaranteed data at a fixed price without worrying about surprise bills.
