Does OnStar do anything anymore?

[c good]

My 2002 Envoy has OnStar. Obviously I never use it. Never did....but...does it still keep telematics type information and transmit or store that info anywhere?

If so, is there any reason to keep it connected?

If not, how do I disconnect it without causing any problems with my Envoy? Thank you all for any input.

Systems made prior to 2015 relied on older 2G and 3G CDMA networks. These older networks were officially phased out by major wireless carriers, causing many of these factory-installed OnStar features to become obsolete.
