Has anyone been able to get a T-Mobile SIM card to work on a 2016 Q5? Since T-Mobile and AT&T use the same GSM technology they should both work, unless Audi has locked out non AT&T SIM cards somehow. I know when Audi used T-Mobile as their service provider you could use AT&T SIM cards.
I have T-Mobile and would rather spend $10 a month for 5gb then pay for AT&T Audiconnect service.
