MobileSIM eSIM Data Plans for China

MobileSIM does not provide a truly unlimited data eSIM for China. All plans that carry an “Unlimited” name in the title give a fixed amount of high‑speed data: 3GB per day for 3–30 days, after which the speed drops to a reduced 1000 kbps. This means the data allowance is still capped at 3 GB per day.

If you need more data, you can choose from MobileSIM’s fixed‑data plans. For example, the “China Unlimited data for 30 days” offers 3 GB/day for 30 days, and the “Asia 100 GB for 180 days” gives 100 GB that can be used over 180 days. These fixed‑data plans can be more cost effective for travelers who need a predictable amount of high‑speed data.

MobileSIM does not provide a China eSIM that includes a phone number or SMS capability. The only options available from this provider for China are data‑only eSIM plans. Travelers who need to call or send text messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict certain apps, so it is advisable to verify the availability of the preferred services in China before making a purchase.

MobileSIM offers 12 single‑country plans that cover China alone, and 22 multi‑country plans that include China alongside other destinations. Of these, 12 are structured as daily data caps—where the allotted data is refreshed each day—while 22 are fixed‑data caps, providing a single, non‑refreshed data allowance for the plan’s validity. Prices for China‑inclusive plans range from $2.34 to $89.00, and data caps span from 200 MB to 100 GB.
