Hi, I want to inform you that I bought my GMC truck on December 3, 2021 with a one month free trial of OnStar with a premium package. I believe all OnStar features were for trial. At first, no functions worked after running the first test. I found a
onstar phone number and called OnStar, one function immediately worked. Called again, hotspot was added, called again, added another feature, called again until most features worked.
