simpleSIM does not provide a truly unlimited data eSIM for Croatia. The plans that carry “Unlimited” in their name actually give 1GB of high‑speed data per day (or 1GB total for the 1‑day plan) and reduce the speed to 512 kbps once that amount is reached, so the data is not unlimited.
Travelers who need more data can choose fixed data plans that offer larger allowances. For example, the simpleSIM Croatia 20GB + Calls & Texts plan gives 20GB of high‑speed data for 30 days, and the simpleSIM Europe 50GB + Calls & Texts plan provides 50GB for 30 days. These fixed data plans are more cost‑effective for users who consume a lot of data.
