SMS Messages Not Received in Google Voice

Well what do you know–just like last year, my Google voice text notifications from Smartthings are suddenly working again as of 8/18/25–hopefully all of yours come back too!

I just ran a test and my Google Voice is also receiving SmartThings text messages.

FWIW, mine stopped working again–last text from smartthings to google voice received 9/17/25 . . . hopefully it’s just a brief outage again like last time….

I figured out that messages sent from SmartThings don’t get through if your number is with a sip provider instead of a regular mobile carrier. For me, switching to a number backed by a mobile network solved it. Seems like some sip provider numbers aren’t whitelisted for automated SMS from platforms like SmartThings, maybe because of how they handle carrier routing.

Very helpful. Thank you.
