Hi firstly I am new here, just asking for some help, so apologies if I have gone about this wrong. I volunteer for a youth division of a local government department. We are holding an event at a council property in Auckland in two weeks and we will need WiFi at the event. There is no public WiFi network there, and we are not yet sure of a physical connection (VDSL/FIBRE) and if we could event use that if it existed.

I was thinking I could purchase a modem with a sim card slot or USB port for a sim card/USB 4G Modem. This will work because I have had to do this before at my own property when the line was being worked on and our ISP gave us mobile data to use. (I used a bridged connection on a PC to turn the phones 4G WiFi connection into an ethernet connection to link into my home network.)

Basically I am curious to see if anyone knows of any company or service provider that will provide 4G mobile data a cheaper price, and that also doesn't require me to live at the address I want the connection at.

For some context I am assuming there will be roughly 150 clients at the event, all using social media. I appreciate any advice that you might have for me.
