SimOptions does not provide an unlimited‑data eSIM for China. All listed plans are fixed data bundles with a hard cap, ranging from 5 GB to 60 GB. For example, the 60 GB plan is valid for 90 days and costs $94.50 USD, while the 50 GB plan is valid for 30 days and costs $78.90 USD. Travelers who need a large amount of data can choose one of these larger bundles, which may be more cost‑effective than purchasing many smaller plans, but none of the options offer unlimited data.
