For travelers from the EU, Croatia falls under the 'Roam Like at Home' regulations, so your EU SIM card should work without extra charges. However, for our UK friends, post-Brexit, many major UK providers like Vodafone UK, O2, and Three have reintroduced roaming fees for Croatia. To avoid unexpected charges and ensure a smooth, high-speed connection from Dubrovnik to Zagreb, an EastESIM is a fantastic alternative. It offers transparent pricing and reliable access to top local networks, giving you peace of mind throughout your Croatian adventure.
