how to text from pc to cell & vis versa?

[Wendy860]

Hi,
My friend who has als has a cell phone and I want to be able to text her from my computer. That way she can have access to me while I'm at work. Does anyone know if I have to get special software to do that, or is there a trustworthy site to do this through for free?
Thank you,
Wendy

You should be able to go to her carrier's website and do it thru there?
