I ported my numbers away after running into so many issues where services would use my native phone number rather than my GV number (placing a call from my car, the person on the other end sees my native number, even though I have everything set up properly)

And living in an area with spotty service... native SMS always send, and the GV "over data" SMS usually fail. Unless they can fix a LOT of issues AND add incentive to come back, I think I'm fine without it for now.
