ChillaxSIM does not provide a true unlimited high‑speed data eSIM for China. All plans that carry the name “unlimited” actually limit usage to 1GB per day; once the daily quota is reached, the speed is throttled to 5120kbps. This is why the plans list a “Reduced speed” of 5120kbps rather than maintaining unrestricted data flow.
If a traveler prefers a fixed‑data option, ChillaxSIM offers several capped plans for China. For example, a 50GB plan valid for 30 days costs $49.90 USD, and a 30GB plan for the same duration is $31.90 USD. These plans provide higher data allowances before any speed reduction applies. Choosing a fixed data plan can be more cost‑effective unless the user is an exceptionally heavy data subscriber who would otherwise need to manage daily caps.
