4G data sim - 30GB+, long expiry

Hi everyone,

I’ll be running some training sessions for groups of 10-20 people and I can’t rely on the existing wifi connection. A little radical independence solves this - 4g router + data sim. I need to pick it up this weekend.

30gb+ and 12-month expiry would be ideal. Most of the training will be in inner-ish suburbs, some as far out as Wantirna - so coverage shouldn’t be a big issue.

I ran across an Optus plan I’m trying to find again - I think it was $100/12m/50gb.

Ps: bonus points for recommending a solid 4g router that can handle 20+ clients doing light browsing (ie not a tiny hotspot).

Tl;dr. Please help me find a decent deal for a 30gb+ Prepaid 4g data plan with long expiry.

Thanks!
