Croatia's inclusion in the EU typically allows for 'Roam Like at Home' for EU-issued SIMs. However, for UK SIM cards post-Brexit, this status has changed. Many UK MNOs, including Vodafone UK, O2, and Three, have re-introduced roaming charges for data usage in Croatia. CoreESIM offers a dedicated plan for Croatia, providing transparent, pre-paid data to avoid unexpected charges for travelers from the United Kingdom and beyond.
