You could give Talkatone a try. It used to be associated with Google Voice, but then Google made some changes that made it incompatible. So Talkatone started its own service. Reviews don't seem great so far, but some people seem to like it.
I have MightyText installed on my computer, tablet, and phone. This allows me to text through my work computer without having to grab my phone, or text through my tablet at the house when my phone is in another room. You can also see when calls are coming in and who's calling. I highly recommend!
