I'd like to preface this by saying that I've done tons of looking around on various forums to ensure that my settings are right and I shouldn't be getting charged, but I am. On the Google Voice Website: No SMS forwarding of voicemails No Texting in the 'phone' settings of my mobile number No text forwarding to e-mail Essentially I have turned off all the texting options in the voice settings. I am not receiving any SMS outside of those on my GV Number, which is now prominently listed all over my ATT bill as having received and sent multiple messages the last few days with my Google Voice number being listed as the 'to/from'. Edit: I should also note that I am only using the official Google Voice App for SMS from my GV Number. I'm open to any suggestions here because I must be missing something.
