How much data does HXVIEW/VIE 4G need in normal usage?

Data usage of this camera depends on the bitrate you set up. 1 hour of live feed in 4MP mode for one channel (default bitrate: 3Mbps) will use about 2GB of data. (In 4MP mode, only one channel is available for live feed). If you use 1GB of data to stream live feed in Fluent mode for one channel (default bitrate: 512kbps), you can watch for about 5 hours, while 1GB of data to stream live feed in Fluent mode for two channels at the same time (default bitrate: 512kbps for each) will last for about 2.5 hours. Based on that, you can estimate the data usage to choose the right data plan for you.
