RedSim eSIM Data Plans for Hong Kong

RedSim does not provide a true unlimited high‑speed data plan for Hong Kong. Every plan listed for the city has a specified data cap in the Data cap column, so none offer unlimited data for the entire validity period.

Instead, RedSim offers fixed data plans that can suit high‑usage travelers. For example, the Hong Kong SAR China 50GB 30 days plan gives 50GB of high‑speed data for 30 days, and the Hong Kong SAR China 20GB 30 days plan offers 20GB for the same duration. There are also daily‑cap options such as the Hong Kong SAR China Unlimited 3‑10‑day plans, which allow up to 3GB per day of high‑speed data before speed is reduced to 1 Mbps for the remainder of each day. Choosing one of these fixed‑data plans can be more cost‑effective unless a traveler requires truly unlimited data.

RedSim does not provide eSIM plans that include a phone number or SMS capability for Hong Kong. Only data‑only eSIMs are available from the provider. Travelers who need telephone or messaging services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Hong Kong before purchasing, as some destinations may block or restrict specific VoIP services.

RedSim provides 17 single‑country data plans and a further 17 plans that include Hong Kong as part of a multi‑country bundle, for a total of 34 options. The single‑country plans range from $1.51 to $63.80 and include data caps from 1 GB to 50 GB valid for 1 to 30 days, while the multi‑country plans cover the same price and data spectrum. Across all plans RedSim offers both daily data cap options—16 plans that limit usage each day—and fixed data amount options—18 plans that offer a set quantity of data regardless of daily limits. The overall price range for Hong Kong‑specific options spans $1.51 to $63.80, and the data cap range extends from 1 GB to 50 GB, giving travelers a broad variety of choices.
