As readers of this blog know, I am facing certain issues with texting Sprint customers via Google Voice (and reading the help forums, I know I am not alone). When Sprint customers text your Google Voice number, it shows up as "text to land line".
Are you expecting an important text message? Well, then you better hang on tight to your phone because if you miss the call and Sprint reaches your voice mail instead, all you get to hear is, you guessed it, "Thank you for using text to land line!"
I wish I had better news but all I can do is point you to the forums where you might be able to find further updates.
