ETravelSim does not provide a true unlimited data eSIM for Hong Kong. The plans that use “Unlimited” in their names actually grant a fixed amount of high‑speed data and, once that threshold is reached, the speed drops to 128 kbps. For example, the Hong Kong eSIM (ZF) Unlimited plans give 4 GB/day over 7, 15, or 30 days, after which the connection is throttled. The China, Hong Kong & Macau eSIM Unlimited packages provide 100 GB for the corresponding validity period, which is also a capped allowance.
If you need a larger data budget without the speed reduction, you can choose from ETravelSim’s fixed‑data plans such as the 50 GB 30‑day Hong Kong eSIM (NZF) for $39.99 USD or the 20 GB 30‑day Hong Kong eSIM (NZF) for $22.99 USD. These options give you a set amount of high‑speed data for the full validity period and may be more cost‑effective unless you are an extremely heavy data user.
