It is desirable to allow mobile stations such as mobile telephones or cell phones to connect to a wireless cellular network even without the presence of a SIM card or other identification information. This is desirable for example, for access to emergency services. By configuring the mobile station to be able to populate replies to request for identification information during call set up which are received from the network, it is possible to avoid redesigning the network while providing "SIM-less" access to the network.
