@tfort2, I think you may be confusing the issue. The charge @ogiewon is referring to is not to us, the users. Hubitat would have to pay for the service that routes the SMS messages to our phone. If everyone has unlimited SMS notifications, that could get expensive very quickly and is probably the reason HE has chosen to limit the number of SMS's.
I have Google Voice and entering my GV number would do nothing to fix the problem. I don't know of any GV api that would allow us to access the SMS feature through Hubitat...I doubt that they do.
At this point, you best option would be to use an online notification service like Pushover (there are other options as well) or setup an email server like below (haven't tried myself because pushover is more than enough for me).
