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.
