Google Voice text messages are failing to send for some, and there might not be a fix
10DLC messaging has been an issue

Google's voice over internet protocol (VoIP) service, Google Voice, has been around since 2009. Google Voice lets you add a phone number to your Google account, allowing you to make calls and send texts over the internet, either using your web browser or a paired phone. It seems like some recent regulation is causing issues for Google Voice users, and it's not clear whether there'll be any kind of resolution.
