ZenSim eSIM Data Plans for Croatia

ZenSim does not offer a truly unlimited data eSIM for Croatia. The plans that carry the name “Unlimited” actually have a data cap, such as 3GB per day on the Croatia Unlimited STANDARD plans or 15GB total on the Balkans+ Unlimited STANDARD plan. Once the cap is reached, the plan’s speed is reduced, although the exact throttled speed is not listed in the available data.

Instead, ZenSim provides fixed‑data plans that can be more cost effective for most travelers. For instance, the Croatia 40GB – 30 days plan gives 40GB of high‑speed data for 30 days, and the Croatia 20GB – 30 days plan offers 20GB for the same period. These options allow users to choose a data allowance that matches their usage without the “unlimited” label.

ZenSim does not provide an eSIM for Croatia that includes a phone number or SMS capability. The current offerings from ZenSim are strictly data‑only eSIM plans for the country. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make voice calls and send messages without needing a local phone number or SMS service.

ZenSim provides 13 single‑country data plans and 13 multi‑country data plans that include Croatia. Prices for these plans vary between $5.00 and $69.00, while data caps range from 1 GB to 40 GB. Some options are fixed‑data plans, delivering a set amount of data for the plan’s validity period, whereas others offer a daily data cap that resets each day. Tethering is allowed on plans that specify this feature.
