My 2014 Captiva used 2G for OnStar, so when that was turned off, I lost service. I see that GM is offering 8 years of basic OnStar service with 2015 models. Does anyone know if it uses 4G or 5G? I wonder if the hardware will still be compatible 8 years from now.
(RIP 2004 Impala), 2016 Impala LTZ Midnight (sold), 2016 Yukon, 2016 Impala, 2019 Cadillac CT6, and 2021 Yukon all use AT&T 4G (LTE) for OnStar in the US. I’m not sure about the Captiva since it’s an older platform, but that’s the best I know.
I have a 2016 Sonic, and I do believe I have 4G OnStar.
Typo. I meant to write 2025, not 2015, and it is too late to edit. I am considering a 2025 Blazer.
