JamboSim eSIM Data Plans for China

JamboSim does not provide truly unlimited high‑speed data for China. The plans marketed as “Unlimited” actually grant 3GB per day, after which the speed is throttled to 1000kbps. If you need higher data volumes, fixed‑data options are available, such as the 100GB plan valid for 180 days, the 50GB plan for 90 days, and a 20GB plan for 30 days. These fixed plans can be more cost‑effective for travelers who consume large amounts of 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 a mix of single‑country and multi‑country data plans that cover China. In total the provider offers 12 single‑country plans and 33 multi‑country plans, with prices ranging from $1.99 to $99.99 and data caps from 200 MB to 100 GB. The plans are available as either daily‑cap or fixed‑cap variants, allowing customers to choose the billing model that best suits their travel needs.
