How does that differ from just having a 1GB allowance? Doesn't sound unlimited to me. Our an I missing something.
I'm not on an unlimited package, but have 1.5GB included. I'd this better or worse than your "unlimited" deal?
I may be missing something, but as far as I can tell, the point of these "unlimited" packages (apart from misleading the unwary) seems to be to make the allowance not part of the contract so it can be varied (as has happened in the past)
