No worries! I think I've come to the same conclusion as you too. It's worth a try on a 30 day sim.

No. One minute past midnight.😉
Just looked at the EE page again, this deal is on 12 month sim, not 30 day and isn't 4G. (see top bar of this page)

EDIT: So confusing. I don't know what 4GEE means. On the 12month sim only checkout page, it also says 4GEE
