Currently, we are using a mobile hotspot to run the Zoom meeting, usually attended by 20+ people every session. It's actually a hybrid meeting, some will attend physically at the shop lot, and some attend online. The connection tends to be very poorat times and not clear for the online audience.

1 option we are considering now is to check with our neighbour if we can rent their wifi, because we only use it for 3 nights (3 hours each)

Is there any other option that are available from telco that may suit our needs?

Something cheap and portable. are those thumbdrive broadband still available?

Some argue what is the difference with the current setup, its still sim based internet.
Im sure using a router should be much more stable and efficient versus using a phone.

I saw some wifi sim routers for like rm80-100, with high numbers of sales - should be legit right?
