Default Can the MMI use your phone's data plan?

Basically what I want to do is to use the wifi capability of the MMI and connect it to my phone's data plan and not be with Tmobile. My phone has wifi hotspot capability. Any one?

This is the way all in car systems should have been designed - the phone is the data gateway, the car doesn't need any 4G electronics, just WiFi. Somehow, none of them were engineered this way - they want to make the car the hotspot when you already have a 4G phone in your pocket that can do that. Makes no sense, I can only guess it was some plan for the auto makers to get some recurring revenue from connecting the car to the 4G network.

Unfortunately, not in North America. In Europe and elsewhere, it's possible if the phone is equipped with rsap.

Actually I think this should be easy to do. Most wifi components work two ways. The Audi should be able to connect to a hotspot with equipment included. I just don't have the technical knowledge on the car.

Yes, it should be easy to do. However, the system has to be designed and configured by the manufacturer for that functionality.

Very true. Not hard at all to design the software and hardware to accommodate tethering. Unfortunately, the wireless phone providers in the U.S. have been mostly successful in maintaining a stranglehold with their revenue streams. They fight anything that would eat into their ability to charge for data wherever possible. When Audi negotiated with T-Mobile (and now AT&T for the A3), I'd guess they had no choice but to design the Audi Connect system to not accept other sources for data communication.

It would be too clever if the car could do that, but Audi would rather have you pay more money for a data plan for the car which is completely stupid !

Audi should realize that the money spent on this extra useless data plan could be used for extra options on their car...

I remember reading an old thread on this forum about being able to pay for data / mapping a la carte using an sd card. Wish I had a more specific memory now that I'm about to get my car. Everyone who was using it loved it from what I recall.

Snagitseven, does this ring a bell?

That discussion was a solution of using a different SIM card (not an SD card) from another wireless provider. However, it still is a separate service from your cellphone.

This discussion is about using the data portion of your regular mobile phone account and get the car system connect to it, so you would not need a separate mobile data account for the car.

Sure. P-Tel and TruPhone, to name two, offer pay-for-use sim cards (not SD cards) which use the T-Mobile network for Audi Connect. Do an AW global search for either one and you'll find lots of threads. Note that if you will be using the Google Earth overlay regularly more than the cached 20 mile or so radius from home or the car's hot-spot wifi (both can be data hogs), you might come out ahead with T-Mobile's 30 month prepaid unlimited data program for Audi Connect which works out to $15 @ month after the 6 month trial. As mentioned, these will not be a phone tethering solution.

It's really not too much different than buying or adding a phone. The car's essentially a data-only smartphone so would need to use someone's service. Even when adding another phone or tablet to an existing contract, there's usually an extra monthly charge by the carriers. Also, there's no requirement that one pay for Audi Connect - the car's nav will still function fine with it's internal POIs, voice command, etc, albeit without the extras. (And totally useless is a matter of opinion - I use Audi Connect every day and find it to be worth the cost).

I don't think you guys understand that this can be done by some simple hacking. It's not my area of expertise but having a sim card slot and SD card gives you lots of options specifically connectivity. As someone that hacks Android phones on a regular basis, I have to tell you that I bet you that this can be done. I am posting this issue in some tech and wireless forums to see if someone can come up with something to re-configure this. I use my 2014 A7 as a test one and will report. This can be done and has to be done. Don't give up so easily.

I anyone has links or documents on the specifics of this system I'd appreciate it. Let the games begin Happy hacking

LOL. Can't wait to see how that comes out.
Can VCDS create missing hardware and does anyone know how much it costs to replace a fried MMI module?

Audiphobe have you had any luck with a non T-Mobile SIM card in your 2014 A7?
I have the same car and my T-Mobile is up and want to see if I can put in a Verizon SIM card.

Not going to work in this car without changing the telephone module and lots of recoding (and presumably money) and I've not read of anyone attempting this. Verizon uses different cel radio frequencies (and hardware) than T-Mobile. Unlike some recent phones, i.e. iPhone, Audi does not use multiple, universal frequency bands. The only carrier sim besides T-Mobile that will work is AT&T, and then only at slow 2G speeds, a band which is shared by T-Mobile. (The new 2015 A3 uses AT&T 4G instead of T-Mobile).
And as mentioned here and discussed in many other threads, you can use an alternate provider's sim so long as they use the T-Mobile network. Do an AW search.

So what you are saying is that the Sim slot in the US version of this car is unlocked?

sorry, I have not done anything about this. Personal stuff in my life has put this on a back burner.

But I am amazed that you guys are still talking about exchanging sim cards and what not. This thread wasn't started to talk about that. Plenty of threads talk about alternates to tMobile plan. From what I understand, paying $450 for three years is a pretty good deal if you use Google earth images and search. So I'm not going to even worry about going with these tMobile resellers. Not worth it.

This thread started for us to look for a way to connect the MMI to the data plan of our phones. My android phone is rooted and I have the capability of using the data plan as a wifi hotspot. Why not be able to use that with the MMI. I understand it is difficult and will carry some risk. But in the phone hacking world, people get together, donate money and buy a phone for a developer to test different hacks on it. I thought maybe we could do that here. I'm not familiar with it and was going to bring it up in a wifi/wireless forum to see if it could be done. I was under the impression that many hardware components that have the capability of being a wifi hotspot can also receive data from a wifi hotspot. Don't quote me on that. I will try to make a post tonight.

Go ahead make fun of me for wanting to try this but at least I'm doing something about it.
