Airdatalink does not provide an unlimited data eSIM for Croatia. All of its plans for the country have a fixed data cap and a set validity period.
The available options are fixed data plans, such as the Essential Europe eSIM with 50GB for 30 days and the Discover Europe eSIM also with 50GB for 30 days. These plans offer 5G where available, include tethering, and are valid for the specified number of days. Choosing a fixed data plan can be more cost‑effective for most travelers unless they require truly unlimited data.
