I bought myself and family a 2018 crew cab 1500 used since my 2004 extended cab was getting cramped on every one. The 2018 has on star and built in wifi that is active for a 30 day trial period. I don't care for the on star mess but the wifi would be handy for the kids when on trips and stuff for their tablets. I set up the my chevrolet app and looked up some online but it doesn't say much if I can just do the data plan for wifi with out on star. Does any one know if this is an option?
