im also on the 600mins unlimited texts* and unlimited internet* im currently siting at around 700mb this month, i rarley go over 500mb but after reading the vodaphone forum was under the impresion i would just be contacted if i consistantly went over it and asked to upgraded my data plan, ive hd no text from them and have recieved no notice from them that they are changing their T&C's either by letter or email,
i would be very interested to see where this goes as the unlimited data plan was why i chose this contract, and i will look to get out of it if they charge me for just going over now and then.
