You know, sometimes OEMs' use the same parts on different cars just with a different part code.

BMW uses the "SA638" code to indicate the feature, but it can use different parts in different models. And true, sometimes they use similar parts on different cars. But in this case, the E60/E63 module will not work. The electrical connections are totally different.

You have done everything I can think of. Given that you have the problem with two different SIM slots, that eliminates a bad contact in the TCU. So, it appears that the TCU is having difficulty either reading the SIM or doing something on the network to validate the SIM. Maybe there is something that the phone carrier can do. I am kind of at a loss now, because the U.S. does not use this type of technology, so I have never seen it first hand.

I am pretty sure that you can buy one of the TCU part numbers I listed above and just replace it with yours. You may need to get a dealer to code it after installation. I assume it should connect with your existing handset.
