Holafly

Instead of capping your data to a fixed amount, Holafly sells unlimited-data eSIM plans for mainland China at one price for the entire trip. This approach appeals to travelers who'd rather avoid the anxiety of watching a data meter decline or running out halfway through.

You pay once, use as much data as you need, and stay connected without rationing. It's simple, particularly if your trip involves plenty of navigation, maps, or streaming.
