Are there any good full-VoIP (SMS + Calling) solutions for android?

---

Now I've come to realize that it's possible for me to get a 1 GB data only plan for my cell phone for $15 a month.

In light of this, I've decided to try and find a way to conduct all my phone stuff over the internet, which is waaay cheaper than a standard phone + data plan. I'm also out of reception both at home and work, so what I have now is pretty useless since nobody can ever get a hold of me. On top of that, I'm a pretty lazy guy - so being able to receive phone calls directly on my computer would be nice.

So far the most viable solution I've discovered is Skype. I can dial out anywhere for $3.00 a month, and I can receive calls with a phone number that forwards to my Skype account for ~$6.00 a month.

The only thing that kills it for me though is SMS. Skype cannot receive SMS messages under any circumstances (since Skype lines are actually land lines, or something) - and it's expensive as hell to send them (~10 cents each).

So now I'm looking for a plan that has basically all that, but also SMS (preferably at least 50 to unlimited a month). The most viable option I've seen so far for this is Google Voice, but it isn't really available in the way I want in my country (Canada), and all the ways to get around it seem to be obsolete.

So at this point, I'm pretty close to just saying 'screw it' and forgoing SMS.
Before I do that though, does anyone know if this is really the best solution? I want to make sure there isn't some super awesome smaller VoIP service I don't know of out there with much better rates .

Thanks!

EDIT: Nevermind...
