I use it all the time, with my vzw friends and family too. Only downside is without the google voice app for my handset. I call my google number, and then dial out, and I can't sdee the number in my call log.
Other than that, I love it.
SMS count as out of network msgs, on VZW at least.
Here is how it works for free SMS, sing in to your google voice account on a pc (www.google.con/voice), under settings select deliver SMS via email, that way you get them as an email, you will be able to reply via email, or open google voice app on the phone, menu address book, and SMS using google voice, that's it.

OK, so I just Dled the app, and with the app on my handset this is the ish. I even paid for my goog # on ebay.
As jnepsa said outgoing are unlimited, but incoming is based on package.
The outbound are handled similar to pin, but inbound as far as i can tell, and just repeating this at this point, forward to the cell # and are out of network. But how that affects your billing is based on price plan/features.
Tested this with my phone and my wifes phone. the message sent from google app (data billing) and the reply was recieved in SMS/MMS folder (text/sms billing)
But now that i have the app, I am even more in love with it :07:
