Out of interest does anyone know what happens if you exceed the limit? Do you have to pay for the extra data, or will they cut you off or will they do like most ISPs and just slow you down?
from o2:
Regarding the fair use policy, since we don't expect the vast majority
of our customers to reach this limit, we will deal with customers that
go over it on a case-by-case basis. We will be flexible with the limit
and point out to customers where they have gone over, but we will not
cut off their service.
