Telematics SIM Card

Sun Apr 10, 2011 1:18 pm

So while I was making/installing the vps auto-disable, I took the opportunity to check out the telematics module since it's behind the glove box as well.

I pulled the SIM out and put it in a test phone. Unfortunately it wasn't as cool as I thought it might be. I had all kinds of ideas, but it's a bit more complex than I thought.

So the SIM registered fine.
I knew the system used text messages and data. So I logged onto carwings and requested an update.
A few seconds later the phone gets a text message:
NISSAN_EVIT_TELEMATICS_CENTER

Cool! So I sent another request to start charging. A few seconds later another message comes in, but it says the same thing.

So apparently they are simply using SMS to trigger the system to connect to the telematics server, and all the real 'talking" is done over the data connection.

I tried to make a call with it and surprisingly, it went through. But I didn't answer the call, I was worried it might flag my account, as if I haven't done enough already to do so.

The "phone" number is odd. I was expecting a standard phone number, but it's not as far as I can tell. It came up with a 15 digit number. I tried to send it a text, but my sprint phone said that the number wasn't valid.

So that was about it. I didn't try much else, I just put it back hoping I didn't screw anything up.. So far it seems fine.

Sounds like an International number. I would try dropping the first number in favor of a "+" sign. I bet that would do it!

I was thinking about that, but I know nothing about international calls/calling.

The number is:

8823507000xxxxx

So a little digging and 882-35 is the international network number for Jasper Systems, inc, which happens to partner with AT&T

Nice! Way to go turbo2ltr! Now if we can somehow find a way to track our Leaf's Telematics mobile number...

That's actually pretty smart. I'll bet they are doing the real communications securely. This means that even if some jerk figures out your car's phone number, the worst he or she can do is make it connect to the telematics server.

you do realize that all activity on the cellular network is recorded as soon as the "send" button it touched?

your provider only gives you billable details, but all calls are recorded. this is how performance metrics are determined. drops, overloads, etc.

Yup, I used to work on Nokia base stations for AT&T. The big difference is if I don't answer, it doesn't show up on the bill!

true and they wont do anything about it anyway. they will just reverify your Sim and the Car SIM and move on

Is this the same number that shows up on your Carwings info screen?
