MobileSIM eSIM Data Plans for Hong Kong

MobileSIM’s “Unlimited” plans for Hong Kong are actually capped at 3 GB per day. After the daily limit is reached the speed is reduced to 1 000 kbps, so they are not truly unlimited high‑speed data. Consequently, MobileSIM does not provide an unlimited data eSIM for Hong Kong.

Instead, MobileSIM offers fixed‑data options. For example, a 20 GB plan for 30 days costs $29.00 USD, and an 100 GB plan for 180 days is priced at $185.00 USD. These plans give a large data allowance at a flat rate and can be more cost‑effective for travelers who consume a lot of data.

MobileSIM does not offer Hong Kong eSIMs that provide a local phone number or SMS capability. All of its Hong Kong plans are data‑only, meaning you cannot make or receive SMS or mainline calls through the eSIM itself. For messaging or voice communication you would need to rely on data‑based VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection provided by the eSIM.

MobileSIM provides 12 single‑country plans and 15 multi‑country plans for use in Hong Kong. The available plans range in price from about $1.50 to $185 and offer data caps between 200 MB and 100 GB, with validity periods spanning 3 to 365 days. Some plans have a fixed data allowance that can be used at any time, while others provide a daily data reset, giving customers flexibility depending on their usage patterns.
