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), shown in
“Core AT Commands” on page2-9. 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.
