MobileSIM eSIM Data Plans for China

MobileSIM does not offer truly unlimited data eSIM plans for China. All plans that include “Unlimited” in their name actually provide a capped amount of high‑speed data—3 GB per day—beyond which the speed is reduced to 1000 kbps. While high‑speed data is available initially, this throttling means the plans are not unlimited in the sense of unrestricted, full‑speed usage.

If a traveler needs more data without the speed reduction, MobileSIM offers fixed‑data alternatives. For example, the China 20 GB for 30 days plan delivers 20 GB of high‑speed data for a month at $40.00 USD, and the Asia 100 GB for 180 days plan provides a larger data pool for a longer period at $185.00 USD. These fixed plans can be more cost effective for users who require extensive data while avoiding the reduced speed that comes with the “Unlimited” named plans.

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 offers 12 single‑country data plans for China and 15 multi‑country plans that include China. The available plans range in price from $1.50 to $185, and cover data volumes from 200 MB up to 100 GB, with validity periods between 3 and 365 days. Some plans are based on a fixed data amount, while others use a daily data‑cap model.
