1 Boot LOG Instruction
The UART outputs +PBREADY after the phonebook is available.
The module reports +EUSIM:ERROR after its SIM card is unplugged.
If the module is booted in automatic baudrate detection mode, send AT 10 seconds after the module
is powered up to check if the AT function is initialized. The UART responds with OK if AT is initialized
and outputs +PBREADY after the phonebook is available.
Network indicator status
âš« Off: No network found.
âš« On: the module finds a network and the PDP context is not activated.
âš« Blinks (on for 0.2 seconds and off for 1.8 seconds): the PDP context is activated successfully.
