Trying to figure out what LTE bands / GSM frequencies are supported here in the US on the MMI system in the 2015s. Thinking of pulling the trigger on an A3 but want to make sure everything works how I like it.

Reason being I want to stick a T-Mobile SIM in for connectivity. Why? Since I can add 5GB/mo of data for $10/month (T-Mobile match my phone data promo).

I know that T-Mobile supports a subset of AT&Ts bands and is redoing their 4G network to support 1900Mhz like AT&T. So I'm hoping that this would work.

Now if they could only fix Siri... Siri works great on my TT Mk2 with an RNS-E!

There's another thread about this somewhere I believe. From what I've read it can be done (another carrier's SIM).

The thread is called "Audiconnect & AT&T 4G". I'd link to it for you but haven't figured that trick out yet. They do specifically say they have successfully used a T-Mobile card.

I think I'm the guy who started that thread.

I confirm.

Been using a t mobile sim for months.
