Confidential / Released

Note

• It is not recommended to use the

AT+COPS

command before passing the CHV (card holder verification) / SIM

PIN1 verification. This is because after PIN1 verification the module will automatically try to register to the

network as though

AT+COPS

were 0, regardless of the settings done before with or without SIM, such as

AT+COPS

=2 which remains unchanged. Also, the test command should only be used after PIN1 authentica-

tion.
