nextSIM eSIM Data Plans for China

NextSIM does not provide a truly unlimited high‑speed data plan for China. The plans labeled “Unlimited” actually contain a capped amount of high‑speed data—typically 1 GB or 2 GB per day—after which the speed is reduced to 512 kbps or 2000 kbps. For travelers who require more data without speed throttling, fixed‑data plans are available. For example, the 20 GB 30 days Economy plan offers 20 GB of high‑speed data, and the 50 GB 30 days Premium plan provides 50 GB. These fixed‑data options are often more cost‑effective for users who consume large amounts of data.

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.
