NextSIM does not offer a plan that provides truly unlimited high‑speed data in Hong Kong. The plans labeled as “Unlimited” carry a fixed data limit of 1GB or 2GB either per day or for the total validity period, after which the speed is throttled to 512kbps or 2000kbps. Because of this data cap, the high‑speed data is not unlimited in practice.
Travelers who need more data can choose nextSIM’s fixed‑data plans. For example, the 50GB plan for 30 days is priced at $47.85 USD, and the 20GB plan for the same period costs $21.11 USD. These fixed‑data options can be more cost‑effective for users who consume large amounts of data and do not require a true unlimited data bundle.
