I have the LG Viewty, otherwise known as the LG KU990i. I was thinking is there anyway to set up the phone to send texts via GPRS/3G(internet)?

Thought this would be a good idea if possible as 3G give 150MB of internet and sometimes its hard to complete it so it'd be good to blow it on texts.

I dont think it is possible, i've tried fiddling with the phone and cant really find that settings, or whether its possible with the network operator '3G'. Thought i'd ask anyway incase it is possible.
