JamboSim eSIM Data Plans for China

JamboSim does not provide a truly unlimited data eSIM for China. Plans marketed as “Unlimited” give 3 GB per day of high‑speed data; once that daily allowance is reached the speed is throttled to 1000 kbps.

Travelers who need a higher data allowance can choose from JamboSim’s fixed‑data plans, such as the 20 GB plan valid for 30 days, the 50 GB plan valid for 90 days, or the 100 GB plan valid for 180 days. These plans offer a larger total data allocation without the daily restriction, which may be more cost‑effective for heavy data users.

JamboSim provides a range of China‑covered eSIM plans that include a phone number and the ability to send SMS. The plans start at 1 GB for 7 days for $11.99 USD and go up to 20 GB for 365 days for $101.99 USD. All of these plans use a dialing code of +1, which is a North American number; calls may be made but not received, and SMS can be sent but not received. The included phone number and outbound SMS functionality is limited to outbound traffic; inbound calls and messages are not supported. As always, it is a good idea to confirm the exact capabilities with JamboSim if you require specific local features.

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.
