MobiMatter does not provide an unlimited data eSIM for Hong Kong. All of its Hong Kong‑covering plans have a fixed data cap, ranging from 35GB to 50GB, and a set validity period from 90 days to 365 days. Travelers who need a large data allowance can choose from several fixed data plans, such as the Asia 7 Countries 50GB plan valid for 90 days, the Best World 50GB plan valid for 180 days, or the China HK Macau 45GB plan valid for 365 days. These fixed data plans can be more cost‑effective for most users, unless a traveler expects to consume data beyond the plan’s cap.
