Xoom to non-smartphone SMS

[reber1b]

Hi all, from a noob. I am a new Xoom owner who has never owned a cell phone of any kind. My daughter and grand daughter both have non-smartphones, and are very adept at texting. I am interested in an app that will allow me to text with them without having to go through each other's email accounts. I tried Heywire for a while, but it seemed to use an inordinate amount of battery power, and seemed to do so even after a forced stop, so I uninstalled it. Now I'm back to looking for a new app, and for all I know, an app may not be the way to go. My question then, is: what is the best way to do what I want to do, whether with an app or otherwise? Also, I'm guesing that IM is out of the question since they do not have smart phones. As stated earlier, I know little or nothing about cell phones, smart or non-smart.

Thanks in advance

Had to edit my post cuz I had it in my head that the Xoom was a phone. As far as I know, there's no way to text from an Android tablet.
