amazing 
1st time i get on in ages and my mic bugs out !?!?
ahh well maybe in another couple months 

Not sure what Portals is doing but it looks like he connects once with a computer (Portals999) and a second time with a portable device (Portals888).
No idea how much data it would consume but if computer has difficulties, you should log on with your smart phone/tablet and speak through that.
If you create a second Zoom account you could have video on computer and audio on portable device. Turning off the video on your portable device would drastically reduce the data consumption.
