Roamless does not provide a truly unlimited data eSIM for Hong Kong. All Hong Kong Unlimited plans listed in the catalogue give 3 GB per day at full speed; after that data is throttled to 1 Mbps. The plans have fixed validity periods ranging from 1 day to 90 days, and the data cap is a hard limit for each plan.
If an unlimited data experience is required, travelers can consider Roamless fixed data plans such as the Hong Kong Data Plan, which offers 50 GB for 30 days at full speed, or the Pay‑as‑you‑go option that provides 150 GB of full‑speed data with no expiry. These alternatives give larger data allowances and, in the case of Pay‑as‑you‑go, allow the user to top up credit as needed.
