ZenSim does not offer a truly unlimited data eSIM for Hong Kong. The only plan that carries “Unlimited” in its name – the Hong Kong Unlimited STANDARD – 5 Days – actually provides 3 GB per day, after which the speed is reduced to 1000 kbps; this is a capped plan rather than an unlimited one.
Instead, travelers can choose fixed data plans that provide larger allocations with no speed throttling while the data remains available. For example, the Hong Kong 40 GB plan valid for 30 days costs $44.10 USD, and the Hong Kong 20 GB plan is available for 15 days at $24.30 USD. These options give users a greater data allowance for a set period and may be more cost‑effective for most users.
