Yes. The one in the Carwings Unit ID "SIM ID".
Mine is 19 digits long. Is the phone number in there somewhere?

I suspect they all say:
"TCU Phone No: ****"
I haven't found it in the diagnostic screens either.

Put your sim in a tmoble phone and call your home with caller id. That should get you the car phone number.

The SIM ID (or ICCID), which doesn't contain any phone number information, in fact, its not even stored on the SIM. You have to make a network request for this.

Yeah the sim ID shown in the carwings screen is not the phone number.

Mine has *** for the phone number as well.

Re: Telematics SIM Card

Anybody use an AT&T Microcell and successfully determine the Leaf's 10-digit wireless number to program into the Microcell? I've spent hours with AT&T as well as Nissan and no one can come up with that number. Can't communicate with the car at home because of poor wireless coverage unless I can register it's number with my Microcell.

Any help?

You have to take the SIM out and make a test call, but its an "international" number, and I highly doubt the microcell will let you put it in.

Wow.. that's a really good question. I have no idea.

It's possible that the telematics SIM does not have a standard 10-digit phone number at all, and can't be selectively enabled on your microcell.

I have a Microcell and would like to assign a number for the LEAF too. I'm parking and charging outside since my stucco is an effective faraday cage and the telematics already has a low signal outside so going in the garage will snuff out most of the remaining signal. So if anyone figures this out it would be helpful to route the signal through the microcell when the LEAF is inside the garage.

Taking out the SIM card is not really a solution for most of us, and really shouldn't be necessary.

Curiously, when you use either of the functions intended to give you ID information about the Telemetrics system, the SIM number it gives you is one digit shy of a true AT&T SIM number. Those are 20 digits, and the Leaf only yields 19. I wonder if this is intentional or if this is the convention in Japan (19 digits). In all cases, the SIM can be translated into the phone number by personnel with access to the AT&T database, but without the entire SIM, there is no way to accomplish this. I had an AT&T tech try mine by adding each of 0-9 to the end of the 19-digit SIM number with no luck.

If you use ID Check, the number the unit gives you as the Unit Telephone Number is about 15 (can't remember exactly) digits--more than a US standard 10-digit number, but also more than an international number. Additionally, the first four digits are 8823, which cannot be made into a country code. I believe this number is actually the MSISDN, which I do not think is the same as a phone number, and about which I know much less than about SIM numbers.

It's a puzzler that I wish I could solve.
