Saily’s plans that carry the “Unlimited” label for Hong Kong are not truly unlimited high‑speed data. Each of those plans is capped at 5 GB per day; when the daily cap is reached the speed drops to 1 024 kbps. Because the data allowance is limited, the plans are not suitable for users who need large volumes of unrestricted high‑speed data throughout their trip.
Instead, Saily offers fixed‑data options that give a larger total data allowance in a single plan. For example, the Hong Kong 20 GB plan for 30 days and the Asia and Oceania 25 GB plan for 60 days provide more high‑speed data upfront and can be more cost‑effective for travelers who need a substantial amount of data without daily caps. These fixed plans avoid the speed reduction that occurs on the “Unlimited” plans.
