MobileSIM eSIM Data Plans for China

MobileSIM does not provide a true unlimited data eSIM for China. The plans labeled “China Unlimited data for X days” offer 3GB of high‑speed data per day, and once the daily limit is reached the speed is reduced to 1000kbps. This means each plan contains a fixed data allowance rather than unlimited high‑speed data.

Users who need larger data caps can choose one of MobileSIM’s fixed‑data options. For example, the China 20GB for 30 days plan provides 20GB of high‑speed data for a single month at $40, and the Asia 100GB for 180 days plan offers 100GB of high‑speed data for five months at $185. These fixed‑data alternatives are more cost‑effective for travelers who need substantial data without the speed reduction that comes after the daily 3GB limit.

MobileSIM does not provide an eSIM plan with a local phone number or SMS capability for China. Only data‑only eSIMs are available from this provider. Travelers can still make calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection.

MobileSIM provides 12 single‑country plans that cover China only and 15 multi‑country plans that include China as part of a broader regional offering. The available plans range in price from about $1.50 to $185, and data caps span from 200 MB to 100 GB. Some plans offer a fixed data allowance while others use a daily data cap, giving users flexibility to choose the type that best matches their usage.
