If you plan to use your mobile phone while in Croatia, be aware of and look into international data roaming charges as well as any likely call costs. Croatia operates on a GSM 900/1800 frequency, so it’s also important to ascertain if your phone is equipped for this frequency before travelling.
Travelers often buy kits with a simple phone equipped with a prepaid SIM card.
Or, alternatively, if your phone is unlocked and compatible, it is possible to purchase a pay-as-you-go SIM card in Croatia through a start-up package offered by Croatia’s mobile phone operators.
A growing number of hotels, cafés, and hostels offer customers free wi-fi access, and internet cafés can be seen in many Croatian cities and resorts across the Adriatic.
