MobiMatter does not provide an unlimited data eSIM for China. All of the plans listed for China have a hard data cap, ranging from 45GB to 60GB, and each plan has a specified validity period.
Travelers who need a large data allowance can choose from MobiMatter’s fixed data plans. For example, the China Korea Japan 60GB 90 days plan and the Best World 50GB 180 days plan offer substantial data limits and longer validity periods. These fixed data plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer.
