Every night, possibly several times per day, I get a text message that says my car has been charged, etc. I want to either disable those, or, ideally, change the phone number those are going to as they consume my cell account minutes when a SMS is received.
You can just reply "stop" to the onstar text and it won't alert you anymore. As for changing the number, you might have to call onstar for that unless there is an option to change the number somewhere in their account settings page.
