Instabridge does not provide an unlimited data eSIM plan for Croatia. Travelers who need a large data allowance can choose from Instabridge’s fixed data plans, such as the 20 GB Croatia eSIM Mobile Data Plan, which is valid for 7 days, or the 10 GB Croatia eSIM Mobile Data Plan, which is valid for 30 days. These fixed plans offer substantial data limits and can be more cost‑effective for most users unless they require truly unlimited data usage.
