Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 77
SIM PIN2 ME is waiting for PIN2, when the attempt to access PIN2 requiring features was
acknowledged with +CME ERROR:17 (e.g., if the user attempts to edit the FD
phonebook).
SIM PUK2 ME is waiting for PUK2 to unblock a disabled PIN2. Necessary if preceding
command was acknowledged with +CME ERROR:18.
PH-SIM PIN ME is waiting for phone-to-SIM card password if “PS” lock is active and user
inserts other SIM card than the one used for the lock. (“PS” lock is also referred
to as phone or antitheft lock).
PH-SIM PUK ME is waiting for Master Phone Code, if the above “PS” lock password
was incorrectly entered three times.
PH-NET PUK ME is waiting for network personalization unblocking password
Notes:
• Whenever the required password changes, <counter> changes to reflect that change. Please refer to the
examples below.
• For passwords associated to the phone lock (“PS” lock set by user or factory) or other factory set locks, such
as “PF”, “PN”, “PU”, “PP”, “PC” the number of attempts is subject to a timing algorithm explained in AT+CPIN.
If these passwords are incorrectly entered the counter first returns 3, 2 and 1 remaining attempt(s), but then
gives the total number of attempts which amounts to 63 (see example below).
• See also commands AT+CLCK, AT+CPIN, AT+CPIN2, AT+CPWD, AT^SLCK for further information on locks
and passwords.
• This command is not PIN protected.
• This command is supported in airplane mode.
Examples:
Example 1
The user fails to provide a correct SIM PIN three times. The counter decreases each time. After the counter
reaches zero, the SIM PUK is required. After each failure to enter a correct SIM PUK, the counter decreases.
