nextSIM eSIM Data Plans for China

nextSIM does not provide a truly unlimited data eSIM plan for China. The plans that carry “Unlimited” in their names actually offer a fixed amount of high‑speed data—ranging from 1GB per day to 2GB per day—with a reduced speed threshold once the limit is reached (for example, speeds drop to 512kbps or 2000kbps after the cap). These plans are named “Unlimited” but are not unlimited in the sense of unlimited high‑speed data.

If unlimited data is required, nextSIM sells fixed data plans such as the 20GB 30Days Economy plan for China ($28.47 USD) and the 50GB 30Days Premium plan ($1, 257.01 USD). These plans provide a larger data allowance without a dedicated unlimited label. Users who need continuous high‑speed data should consider buying one of these fixed‑data options instead of the capped “Unlimited” plans.

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 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.
