Ovosim eSIM Data Plans for China

Ovosim does not provide a truly unlimited data eSIM for China. Every plan that carries the word “Unlimited” in its name actually has a daily data cap—such as 3 GB/day or 5 GB/day—and after that limit the speed is reduced.

Travelers who need a large amount of high‑speed data can choose from Ovosim’s fixed data plans. For example, the China 50GB 30Days plan offers 51 GB of data for 30 days, and the China 20GB 30Days plan provides 20 GB for the same period. These fixed plans give a clear data allowance and can be more cost‑effective for most users unless they require continuous, unlimited usage.

Ovosim does not provide an eSIM for China that includes a phone number or SMS capability. The service only offers data‑only plans for that country. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those services are accessible in China before purchasing the plan.

Ovosim lists 40 single‑country plans that cover China and 58 multi‑country plans that include China. The available plans can cost between about $3.41 and $193.63, offer data caps from 1 GB up to 51 GB, and remain valid for 5 to 180 days, with many plans permitting tethering.
