Status
During power-down procedure, the module will log off from network and save important data. After the
module logs off, it sends URC "POWERED DOWN" and shuts down the internal power supply. If the
"POWERED DOWN" URC is outputted, the power on VCC pins can be cut off.

3.6. Reset the Module

RESET# is an asynchronous and active LOW signal (1.8 V logic level). Whenever this pin is active, the
module will immediately enter Power On Reset (POR) condition.
Please note that triggering the RESET# will lead to loss of all data in the modem and removal of system
drivers. It will also disconnect the modem from the network.
