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 actually offer a fixed allowance of 3 GB per day. Once that daily limit is reached, the speed is throttled to 1000 kbps. Travelers who need larger data allowances can instead choose from fixed‑data plans, such as the 20 GB plan that lasts 30 days and starts at $12.99, or the 100 GB plan that is valid for 180 days and costs $71.99. These fixed‑data options allow high‑speed use up to the set limits and may be more cost‑effective for heavy data users.

JamboSim does not provide a China eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for travelers in China.

Use the data connection for messaging and voice by installing popular VoIP applications such as WhatsApp, Telegram and iMessage, which work over the internet and allow calls and text messages without a local phone number or SMS service.

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.
