Our e-tron has been ours for about one week, so the paperwork is fresh, but my knowledge is weak. We have some sort of letter/certificate advising us to contact AT&T or T-Mobile to register and obtain permission to use the "signal booster" in our "phone box equipped" vehicle. We must also use "approved antennas and cables".
What is this? Is it the nice little wireless charger? Is there a SIM card inside somewhere? Is it necessary or an extra?
