Do Three do a rolling monthly Sim-only "contract" for under £20 with unlimited data and enough calls/texts for an Aussie male (that's fuck all, we don't chit chat) ?

Go look.

I'm paying £22 per month on the One Plan for unlimited internet and silly minutes and texts. When 4G arrives on Three in a couple of months it's an automatic upgrade if your phone can support it, and the plan and price does not change.
