nextSIM eSIM Data Plans for China

nextSIM does not provide any truly unlimited‑data eSIM plans for China.
All plans that use the word “Unlimited” in their name actually offer a fixed amount of high‑speed data—such as 1 GB, 2 GB, or 1 GB per day—and after that data is consumed the speed is throttled to either 512 kbps or 2 Mbps.

Travelers who need more data may choose from the fixed‑data plans listed by nextSIM, such as the eSIM China 20 GB 30 days Economy plan priced at $30.26 USD or the eSIM GLOBAL 30 GB 30 days Premium plan for $773.01 USD. These plans grant a clear data allowance without the speed reductions that characterize the “Unlimited” variants, making them a more cost‑effective option for heavy‑usage travelers.

nextSIM does not provide a China eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for China, so there is no option to receive voice calls or text messages through the local network.

Travelers who need to stay in touch can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. These apps allow voice calls and messaging without requiring a traditional phone number or SMS service.

nextSIM offers data plans that cover China in both single‑country and multi‑country formats. There are 34 single‑country plans that are valid for only China, and 35 multi‑country plans that include China among several destinations.

The plans vary in structure: the fixed‑data‑cap options deliver a set amount of data that can be used over the validity period (ranging from 1 GB to 50 GB), while the daily‑data‑cap options reset each day during the plan’s validity, allowing a daily allowance that can be accumulated (18 such plans are available).

Across all plans the price ranges from about $3.58 to $1, 288.35, the data caps span 1 GB up to 50 GB, and validity periods run from 1 to 30 days. Some plans also feature reduced speed options of 512 kbps or 2000 kbps for certain use situations.
