They absolutely do (source, I know there's a sim card in there, they never take it out, it phones home, etc). You get the onstar reports, and can activate it any time using the active sim card.
You can I think get into the box if you have tools, and pull out the sim though. I really want to hack that thing, so I can control the display! I'd love to be able to put linux on my car. And I deserve to. It's mine! I bought it! As long as it's still safe, why does it matter?
