General
If set on the mobile phone, enter the Personal Identification Number (PIN). The mobile phone system then sets up a link to the nearest base station controller and relays the data to the mobile service switching center via the base station controller. Access authorization for the mobile telephone network is granted by the authentication center after the necessary data has been checked in the mobile service switching center.

After registering in the mobile telephone network, in vehicles without code (494) USA version, the name of the mobile telephone network is displayed on the mobile phone screen.
If the nearest mobile service switching center is not the one in which the user was entered in the home location register when the user's cellular mobile telephone was logged in, the user is registered there in the visitor location register. The mobile service switching center then establishes contact with the mobile service switching center, in which the user is registered as a mobile service user, checks the necessary data, and grants access authorization to the mobile telephone network.
The mobile service switching center therefore automatically receives information about the location of the subscriber and can route the incoming telephone calls to the user for as long as he/ she is logged into the mobile telephone network. A location change is updated in the mobile service switching center.
