JamboSim eSIM Data Plans for China

JamboSim does not provide a truly unlimited data eSIM for China. The plans that carry “Unlimited” in their name give up to 3GB of high‑speed data each day; after that, speed drops to around 1 Mbps. Because a daily limit applies, these packages are technically capped daily.

If an unlimited data experience is required, the provider offers fixed data plans instead. For example, the 50 GB plan for 30 days and the 100 GB plan for 180 days give fixed data allowances without a daily cap, although the data must be used within the specified validity period. These fixed data plans can be a more sensible choice for travelers who need large amounts of high‑speed data in China.

JamboSim sells China eSIM plans that come with a phone number and support for outbound SMS. The plans range in price from $11.99 USD for 1 GB and 7 days up to $105.99 USD for 20 GB and 365 days. All of these plans provide a dialing code of +1 and allow users to make calls and send SMS messages, but they do not support inbound calls or SMS. If a traveler requires a local Chinese number or inbound messaging, it is advisable to confirm the specific capabilities directly with JamboSim.

JamboSim lists 12 single‑country data plans that cover China only and 40 multi‑country plans that include China as part of a broader package. The single‑country plans are typically daily data‑cap offerings, allowing a fixed amount of data for a set number of days, while the multi‑country plans are generally fixed data‑cap bundles that can be used across several countries with China included. Across all plans the price ranges from about $1.99 to $105.99 and the data cap ranges from 200 MB up to 100 GB.
