After noticing my car supports AT&T LTE, I'm starting to speculate that it also has a sim card since it's operating on the GSM network AND has an imei number.

Has anyone found the location of the sim card? Onstars response telling me that'd I'd be hacking the vehicle made me very suspicious that I'm correct and that I'd be able to replace the card if I found it....

(which by the way... I own the car. If I want to hack it, I will do so! Just like if I want to crash it...it's totally my choice)

 

So, even onstar says that there is a sim card in my car....

"OnStar® Data Plans (offered by AT&T for OnStar customers): Session-based data plans provide you with access to AT&T’s wireless data services for your equipped vehicle, including but not limited to features that may be used with wireless data services, content and application. Eligible vehicle, data plan, and compatible SIM card req'd"

 

hey how did you get the imei number? Att says that's all i need to start phone service through at&t on my nox.

 

there is a SIm and it is embedded, the terminology you would want to use is ICCID and the onstar advisor will provide both IMEI and ICCID.

 

I live in Sweden and I would like to replace simcard to a card that works here, we don't have the same oprators here.
