nextSIM eSIM Data Plans for China

NextSIM does not provide a truly unlimited data eSIM for China. The plans that carry “Unlimited” in the name actually offer a fixed high‑speed data allowance—typically 1 GB per day or 2 GB per day—after which the speed is throttled to 512 kbps or 2000 kbps. These plans are meant to give the appearance of unlimited use but they are not unlimited in the sense of offering high‑speed data without limits.

If you need higher data volumes, nextSIM offers fixed‑data plans instead. For example, the 20GB 30Days Economy plan is available for $29.97 USD, and a larger 50GB 30Days Premium plan can be purchased for $1 264.89 USD. These fixed plans give you a clear data cap and may be more cost‑effective for heavy data users.

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 58 single‑country plans that cover China alone and 35 multi‑country plans that include China alongside other destinations. The packages range in price from $3.54 to $1, 264.89, with data caps between 1 GB and 50 GB and validity periods spanning 1 to 365 days. Plans are divided into fixed data‑cap options—75 in total, where the allotted data remains constant for the entire validity—and daily data‑cap options—18 in total, where the data allowance is reset each day.
