Warning: This command erases all calibration data, customizations, etc. First
use AT!NVBACKUP to save these settings, and then after using this
command, use AT!NVRESTORE (p.86) to restore the settings.
Note: Profiles (PDP contexts) are not restored using AT commands. The host
application is responsible for implementing this task.
This command resets non-volatile memory to default values and then restores
the modem’s FSN. All calibration data, customizations, etc., are removed.
Note: This command may take 20–30 seconds to complete.
