Roamingo does not offer a true unlimited data eSIM for Croatia. The plan with “Unlimited” in its name, Europe Unlimited for 1 day, has a 2 GB cap, which means speed will be throttled once that amount is used. All other Croatian plans are fixed‑data: for example, Croatia 20GB for 30 days and Croatia 10GB for 30 days provide high‑speed data until the stated data cap is reached, after which a throttled speed would apply. Selecting a fixed‑data plan may be more cost‑effective unless an extremely heavy data user requires no limits.
