VeloeSIM does not provide an unlimited data eSIM for China. All of the plans listed for China are fixed‑data bundles, with the largest available package giving 20GB of high‑speed data for 30 days. Travelers who need more data can purchase a larger bundle, such as the 20GB plan, or they can add a pay‑as‑you‑go top‑up, but none of the current offerings are unlimited. Choosing a fixed data plan can be more cost‑effective for most users, unless the user is an extremely heavy data consumer who would prefer the flexibility of an unlimited plan.
