esim0 does not provide any unlimited data eSIM plan for Hong Kong. All of its Hong Kong offerings are fixed data plans with hard caps. For example, esim0 sells a 50GB 30‑day plan for $37.99 USD and a 50GB 180‑day plan for $61.99 USD, as well as a 20GB 30‑day plan for $18.99 USD. These plans give a clear data allowance that must be used within the specified validity period.
Choosing a fixed data plan can be more cost effective unless a traveler is an extremely heavy data consumer. If a larger data amount is desired, esim0 also offers plans that cover Hong Kong plus additional countries, such as the Asia‑20 plan with 20GB for 90 days or the Global139 plan with 20GB for 90 days.
