Switching a zoom group video chat from laptop to cell phone

[belle79]

When I am using the app and the laptop to run zoom is the data being pulled from only the device I am using at that time? I usually initially  answer on the laptop a lot but wonder if switching immediately to my cell will save my hotspot data and pull from my unlimited cell phone data instead?

Trying not to burn through 35g of Data in a month and we have a lot of live meetings.
