The USIM contains an identity that unambiguously identifies a
subscriber. The USIM provides storage for subscription and subscriber
related information.
The User-to-USIM authentication feature restricts access to the USIM
until the USIM has authenticated the user. Thus, access to the USIM
can be restricted to an authorized user or number of users. Your USIM
Personal Identification Number (PIN) is stored securely in the USIM.
The entry of a correct PIN opens access to the USIM.
The USIM-Terminal Link authentication feature ensures that access to
a terminal or other user equipment can be restricted to an
authorized USIM. The USIM and the terminal share a code stored
securely in the USIM and the terminal. If a USIM fails to prove its
knowledge of the code, it is denied access to the terminal.
If the USIM is removed during operation, the terminal will deactivate
any active PDP contexts, detach from the network, and enter a "NO
SIM" operational mode. If the USIM is reinserted while the MT is still on,
the MT must be restarted to detect the new or replaced USIM.
