ByteSIM does not provide a truly unlimited high‑speed data plan for Croatia. The plans labeled “Unlimited” actually offer 1 GB per day, after which the speed is reduced to 10 240 kbps.
Instead, ByteSIM sells fixed‑data options that may be more economical for heavy users. For example, a 50 GB package is available for 3, 5, 7, 10, or 15 days, with the same tethering allowance and no stated speed throttling after the data cap is reached. Choosing a fixed plan can be more cost‑effective unless a traveler needs an unrestricted amount of high‑speed data.
