Just received a rather sizeable bill for October for my mobile broadband use (on my E71).
I have the Broadband 100MB add on, my understanding was when you hit 100MB, it added another 100MB (I think I've got this confused with Telecom's prepay data).
I spoke to a CSR but am more confused than ever.
How does it work, and should I change the add-on to something more substantial?
