Has anyone had issues with cell phone reception? I cancelled the OnStar Wi-Fi after the free trial was over, I have turned the Wi-Fi off in my car and I turn the Wi-Fi off on my phone when I get in. I seem to never have cell service in the car but I do in other vehicles. I asked Chevrolet if there could be a block so you buy their Wi-Fi service and they said no, that it must be my cell phone carrier but I've never had this issue in other vehicles. One day I have service half way to my destination and other days I don't have it at all, again I travel the same roads that I did in my last vehicle and never had this issue and I still don't have this issue if I'm in someone else's car. Just wondering if I'm doing something wrong or if anyone else has issued this same problem.
