Note: OnStar’s roadside and emergency services only work within the U.S. and Canada, wherever your vehicle actually is. Connect-EZ helps in two situations: if you’re stranded somewhere with no cell
signal but a wifi connection is reachable (a nearby business, a hotspot, etc.), or if you’re managing billing or subscription questions on a U.S./Canada-registered vehicle while living or traveling abroad.
