ive never heard of texts being included with the data plan either. though they should be, text is data
i opted for the 400 text package on top of my $20 unlimited data plan. i didnt even really need that, i probably send 10 texts a month. with the data plan, you can use online aim as much as you want and you wont use text messages. couple that with the unlimited email the data plan gives you and youll see there is hardly a need for texts.
