nextSIM eSIM Data Plans for China

nextSIM does not provide a truly unlimited data eSIM for China. The plans that carry “Unlimited” in their name actually include a hard data cap—such as 1 GB or 2 GB for a single day—and after that limit is reached the speed is throttled to 512 kbps or 2000 kbps.

Travelers who need more data can choose from nextSIM’s fixed data plans, which offer larger, non‑throttled allowances. For example, the eSIM China 100GB 30Days Premium plan gives 100 GB of high‑speed data for 30 days, and the eSIM China 50GB 30Days Premium plan offers 50 GB for the same period. These fixed data plans can be more cost‑effective for most users unless they are extremely heavy data consumers.

nextSIM does not provide an eSIM plan for China that includes a phone number or SMS capability. Its China eSIM offerings are data‑only. Travelers who need voice and messaging can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those services are accessible in China before purchasing.

nextSIM lists 47 single‑country data plans that are exclusively for China, and an additional 45 multi‑country plans that include China among their covered destinations. Across these options the prices range from $3.96 up to $1, 279.01, while the data caps span from 1 GB to 100 GB per validity period. The catalogue also contains 18 daily‑data‑cap plans and 74 fixed‑data plans, and a few plans offer reduced speed limits of 512  or 2, 000 Kbps.
