Hello guys,
we recently aquired a high number of laptop devices with the EM7345 module.
The problem we have: after insertion of the SIM-card, the customer is not able to connect to the mobile broadband, because the APN is wrong. It is predefined to VZWINTERNET. Of course, after you manually change the setting in windows (in this case: Germany, internet.t-mobile.de), or even delete all APN data, the connection works.
My question is: is there any way for us to set the (or at least delete the predefined VZWINTERNET) APN while provisioning the laptops? Is there any way to set an APN even though the module has not been used before in the laptop? So far we have not found any possibility, the different netsh mbn commands do not seem to help.
Any help would be very appreciated. 
Edit: OS is Windows 7 Enterprise.
