Access Control Commands
When the phone or SIM card is locked or blocked, the only accessory operations allowed are
those found in the list of Core AT commands (allowed while phone/SIM card is locked). All other
AT commands are not executed, for example, accessing phone book entries. However, the phone
is still capable of sending asynchronous message events via AT responses, for example, incoming
call notification.
