eSIMNEXA does not provide an unlimited data eSIM for Croatia. The provider offers fixed data plans that include a set data allowance and a validity period. Examples of these plans are the Croatia 60GB 30Days plan, the Croatia 30GB 30Days plan, the Croatia 20GB 15Days plan, and the Croatia 20GB 30Days plan, all of which are 5G‑enabled and have a specified validity of 15 days or 30 days. A Europe 300GB 15Days plan also covers Croatia, but it is a fixed data plan with a 15‑day validity. Choosing a fixed data plan can be more cost‑effective for most travelers unless they require an unlimited data option.
