This is happening to me today after flashing the latest Snapshot. It happens in both the Messaging app and Hangouts. I have people texting me but I cannot respond to them.

This looks like an issue with the cyanogenmod.voiceplus service. But I haven't been able to figure out how to disable it yet. I use Google Voice for voicemails but haven't been using it for texts. I use Hangouts for SMS.

I went into phone settings and made sure to have Google Voice as my voicemail provider.

I went into Google Voice and made sure that Sync and Notifications->Receive text messages 'Via the messaging app' was selected instead of 'Via the Google Voice app'.

This still isn't helping as all SMS that I send are rejected.

Update: Freezing the Voice+ 1.0 app from CM resolved the issue and I can send SMS again.
