No nextSIM plan for China is truly unlimited. All of the plans that carry the “Unlimited” name provide a limited data allowance – for example, eSIM Unlimited Standard 1 Day China offers 1GB of high‑speed data before the speed drops to 512kbps, and eSIM Unlimited Plus 1 Day China provides 2GB before the speed throttles to 2000kbps. After the cap is reached, the data rate is reduced as specified.
If you need more data without the speed cut‑off, nextSIM offers fixed‑data plans such as eSIM China 20GB 30Days Economy for $30.26 or the larger eSIM GLOBAL 50GB 30Days Premium at $1,291.53. These plans give you a set amount of high‑speed data without any speed reduction, making them a cost‑effective choice for travelers who need significant usage in China.
