ChillaxSIM eSIM Data Plans for China

ChillaxSIM does not provide a truly unlimited data eSIM for China. All plans that carry the word “unlimited” in their name offer 1GB of high‑speed data each day; once the 1GB limit is reached the speed is throttled to 5000 kbps.

If an unlimited data experience is important, ChillaxSIM offers fixed‑data plans instead. For example, a 120GB plan valid for 30 days costs $35.90, while a 50GB plan for the same period is $22.90. These examples illustrate that a fixed data plan can be more economical for travelers who need large data allowances over a given period.

ChillaxSIM does not offer China eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available. Travelers can still use popular VoIP apps—such as WhatsApp, Telegram and iMessage—over the data connection for calls and messaging.

ChillaxSIM provides 51 single‑country data plans and 43 multi‑country data plans that cover China. The available offerings span a price range of roughly $1.90 to $115.90, while the data allowances vary from 1 GB up to 120 GB. Some plans provide a fixed data allocation that is valid for the full duration, whereas others grant a daily data cap that replenishes each day. Many of the plans also allow tethering, and a few include reduced speed options of 128 kbps or 5000 bps.
