I remember something like this from last year.

I think the policy at the time was "yeah, unlimited=500mb but if you go over that now and again you won't be penalised. We'll warn you and suggest you buy an additional package it the limit is breached consistently".

I can get 3g in Edinburgh but any access times-out - the network is constantly saturated. I can get a 3g in the middle of nowhere but internet access is fine.

There are obvious abusers of the network so mybe charge them if they persistently offend.

Maybe Vodafone are using a hard line and expecting a more moderate proposal to be accepted.
