ETravelSim does not provide a truly unlimited data eSIM for Hong Kong. All of its Hong Kong‑specific plans carry a fixed data allowance and, once that threshold is reached, the speed is throttled. For example, the “Hong Kong eSIM (ZF) Unlimited – 7 days” plan grants 4GB per day and reduces the speed to 128kbps after the daily allotment is used, while the “China, Hong Kong & Macau eSIM Unlimited – 7 days” offers 100GB over seven days and is likewise capped before any throttling occurs.
Travelers who need large amounts of data but are not extreme users can opt for the fixed‑data plans that are available, such as the 50GB 30‑day package priced at $39.99 USD or the 20GB 30‑day package at $22.99 USD. These options may offer better value when a high‑speed, unrestricted data quantity is not required.
