GETTING STARTED

Configuring Low Power Options

NOTE for MNG3: eDRX and PSM modes are not supported in 2G (all modes are supported using Cat M1).
Refer to Powering Down the Device for lowest power consumption.
To configure PSM:
AT+CPSMS
To configure eDRX:
AT+CEDRXS
To set device functionality:
AT+CFUN
Note: See the AT commands reference guide for AT command details.

Powering Down the Device

To verify that your device is powered down, monitor the 1V8_MON signal (pin 27). When it goes low, the device is
powered down.
Note: Signal 1V8_MON operates at 3.318 V not 1.8V.
Note: Note: AT+CPWROFF will not take more than 40s.

Configuring u-blox Cellular Radio

This MNG3 device uses a cellular radio that can operate on different carrier networks (not simultaneously).
You must configure your module based on your carrier network and application. This includes setting the
applicable MNO profile (based on carrier), RAT (type of technology you wish to use such as Cat M1), and LTE bands
intended for the application device within regulatory compliance. The module is not intended be used in the
factory-default setting.
Depending on your MNO profile, certain elements may or may not be available. Refer to the table for details.
