When I bought my RXL in March 2020, the salesman said that when the initial free wifi ran out (which it has), I would need to buy a new prepaid SIM card. I have looked at the router in the boot but there is no slot to put a SIM card into. Should I assume that he didn't know what he was talking about and I need to subscribe through Lexus. I have a huge data allowance on my iphone so can I use the system to create wifi via the phone. I have checked all over the internet and cannot find anything that helps
