MC55 AT Command Set

5.1 AT+CPIN

s

mobile

is an 8-digit device code associated to the IMEI number of the mobile which can only by obtained from the man- ufacturer or provider. When needed, contact Siemens AG and request the Master Phone Code of the specific module.

There are two ways to enter the Master Phone code:

You can enter AT+CPIN=Master Phone Code,new password.

You can use the ATD command followed by the GSM code *#0003*Master Phone Code#;.

Usually, the Master Phone Code will be supplied by mail or e-mail. If the received number is enclosed in the *# codes typically used for the ATD option, it is important to crop the preceding *#0003* characters and the appended #.

Example: You may be given the string *#0003*12345678#. When prompted for the PH-SIM PUK simply enter 12345678.

If incorrectly input, the Master Phone Code is governed by a specific timing algorithm: (n-1)*256 seconds (see table below). The timing should be considered by system integrators when designing an individual MMI.

SIM locks:

These are factory set locks, such as "PF", "PN", "PU", "PP", "PC". An 8-digit unlocking code is required to operate the mobile with a different SIM card, or to lift the lock. The code can only be obtained from the provider. Failure to enter the password is subject to the same timing algorithm as the Master Phone Code (see Table above).

Call barring:

Supported modes are "AO", "OI", "OX", "AI", "IR", "AB", "AG", "AC". If the call barring password is entered incor- rectly three times, the client will need to contact the service provider to obtain a new one.
