Soracom Mobile does not provide a truly unlimited data eSIM for Hong Kong. All plans listed for this destination have a fixed data allowance, the largest being 10 GB for 30 days at $52.99 USD. An additional option is a 5 GB plan for 30 days priced at $26.99 USD.
If you anticipate using large amounts of data in Hong Kong, a fixed‑data plan like the 10 GB might be more cost‑effective than paying a per‑kilo‑byte fee, but heavy users will still need to monitor usage and possibly purchase additional data if their session exceeds the plan’s cap.
