most people greatly over estimated their needed bandwidth. You could probably get by with 4mbps and not notice a difference on zoom.
You might be able to get a higher speed unlimited through ais 4g,i think they do have at least a 15 maybe 20 option. I have one of their prepaid Sims as a backup and it does work as advertised. Your signal strength is your location is of course going to matter.
They do offer 5g, but I don't think unlimited and its pretty pricey. I would try a 4g first and see if works for you.
Other networks tend to max out around 10mpbs full speed like dtac and true, I got full speed for both, but they don't get much faster.
