If you're lucky enough to live in an area with a good 5g connection then this might be a good deal for you.three.co.uk/store/broadband/home-broadband/three5ghomebroadband
Three 5g home broadband unlimited is £15 for 6 months and £30 after on a 24 month contract (total £630). Otherwise it's £17.50 for 6 months and £35 after for a 12 month contract (£315).
Likewise, the 4g deal is £11 (for 6 months) and after £22 on a 24 month contract (£462). 12 months = £12.50 (6 months) then £25 (£225).
Might be good for people who normally cannot get connected otherwise. Eg in my area to get decent connection speeds I have to either go with virgin media (for £35-£50 for a 200mb/s connection).
