Introduction
The modem has 2 MB of non‐volatile memory that is used to
store:
• Factory calibration data
• Settings made in a host application such as Watcher
The commands in this chapter allow you to back up and
restore the data in non‐volatile memory.
Command summary
The table below lists the commands described in this chapter:
Reset non-volatile memory

Command reference
Reset non-volatile memory
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.
