Command Description
!ACCR? Query SIM code status
Returns the status of the SIM, indicating:
•
whether the SIM is detected
•
what password, if any, the SIM is requesting
•
the number of retries available (if applicable)
The PIN and PUK codes are used to prevent unauthorized use of the SIM. The
PIN code is user-defined. Typically the number of retries allowed on the PIN
code is three. If the correct PIN is not entered within this number of retries, the
SIM becomes blocked and the PUK code is required. Typically the number of
retries on the PUK code is ten. If the correct PUK code is not entered within that
number of attempts, the SIM becomes permanently blocked.
Some modems are configured for use with SIMs of a particular carrier. The MEP
code de-activates the mechanism that restricts the modem to SIMs of a
particular carrier. There is no maximum number of retries on MEP codes.
!ACCR?
returns <code>[,<password retries>].

The number of retries is reported where <code> = SIM READY, SIM PIN, or SIM
PUK.
Note: The SIM is peramanently blocked when !ACCR=SIM PUK,0 is returned.
Use the AT command
+CPIN
(page 89) to enter any codes the SIM is
requesting.
