Response
TA stores a password, which is necessary before it can be operated on (SIM PIN,
SIM PUK, PH-SIM PIN, etc.). If the PIN is to be entered twice, the TA shall auto-
matically repeat the PIN. If no PIN request is pending, no action is taken and an
error message, +CME ERROR, is returned to TE.
If the PIN required is SIM PUK or SIM PUK2, the second pin is required. This sec-
ond pin, <newpin>, is used to replace the old pin in the SIM.
