How much data/ GB needed for Zoom -use?

Hello community,

since i will be traveling and working, I will have to use Zoom without WLAN.

Does anyone know how much Data Volume/ GB I need to buy extra to do Zoom meetings?

Actually about 5 hours.

Do you know how much Zoom Meetings use pr hour?

I really would appreciate your knowledge around that topic here.

Thank you in advance!
