When 'unlimited' is 'unlimited'. Sort of...
Well, the unlimted issue all really comes down to semantics. Obviously Vodafone (and, indeed, all the fixed and mobile operators) do not themselves have access to unlimted bandwidth, so, by definition, their customers cannot either. So, strictly speaking, no-one has access to unlimited bandwidth.
In my view, it is fair enough to describe access to the Internet as 'unlimted' if there are no 'hard' limits to usage. Unlimited means so much more than just 'bandwidth' too. For instance, most operators data packages initially restricted users to the operators' own 'walled gardens'. So, a data package that allowed unlimited access to the Internet could be viewed as a package that allows access to all web sites/email servers/VoIP etc. 'withput limitation'.
Now, for me, they key issue is with the Fair Use Policies. Do these create hard limits? If Voda's billing systems start charging you the moment you use more than 120MB a month, then this cannot be described as 'unlimited'. If, however, they simply warn you (e.g. via SMS) if you go over 120MB in a month; and only then start charging or take away your data package if you consistently go over this limit; well, that's sort of fair enough. Remember, Voda etc. do not have unlimited bandwidth, so if some users are tkaing the piss, it reduces speed/availability to other customers under normal use.
The question you have to ask yourself as a user is 'is the FUP limit sufficient for my normal use?'. If it is, then the usage is effectively --for you -- unlimted. In my view, 120MB is too low. 1GB for a month of mobile use for me is probably fine.
Paris, 'cos she's responsible for a fair amount of bandwidth usage...
