Sms text messages free with google voice?

I recently got a galaxy s phone with a 200mb data plan and zero text messages. I heard about google voice, where you could text for free using a data plan. Is this true? I don't want to end up getting a huge texting bill at the end of the month.|||As long


as you


send


the SMS


through


Google


Voice


you


are not


using


your


carrier


for


anything


other


than


internet


data


(which


they


will


charge


you


for)


and


thus


you


will not


be


charged.


If you


have it


setup


so GV


will


send


you an


SMS


then


that


will


use


your


carrier


and


thus


you


will be


charged.|||Yes it is! Don't do it ! LOL :P
