How much mobile data will you use in China?
Build a conservative estimate from the activities that actually consume your data. No email, signup, or account required.
Trip length
How many days?
Set each activity to the level that feels realistic, then calculate a conservative range.
Choose a buffer, not a fantasy scenario.
The calculator gives a range because mobile data is never perfectly predictable. Choose a plan near the high end if losing service would be disruptive; choose closer to the middle if you will use hotel Wi-Fi and can top up.
Important: “Unlimited” does not automatically mean unlimited hotspot sharing or permanently full speed. Compare the current provider terms before paying.
