This application note defines the different QoS levels and how they are set up and managed in LTE networks to use on AirPrime MC/EM74xx embedded modules.

The Sierra Wireless MDM9X15 and MDM9X30 family of modems support carrier switching. This is a feature where the same modem can be used with different carriers from different geographies by downloading and activating the correct FW package for the carrier and modem. This document explains how customers can match a FW package with the correct supported modem.

This document describes the network interface configuration on Linux and Windows when an AirPrime HL75xx embedded module is used.

This application note describes how to design a Dual SIM solution without using the SIM detection pin of the module.

This technical note will explain how to collect HL77xx module logs over USB in the Linux environment, defines the ACM ports, presents custom AT Commands to use for this functionality, and more.

The AirPrime HL7588 supports up to 4 PDN connections. This Technical Note gives examples/steps to make multiple data connections with different APNs. The customer can use the same method to establish multiple PDN connections on different networks.

AirPrime EM74xx modules support dual SIMs or 2 physical slots. This technical note provides information regarding the dual SIMs functionality.

The Sierra Wireless AirPrime MC73xx and MC74xx modules can enumerate in different states. It is imperative for host applications to be aware of the different states and handle them appropriately. This document covers the Qualcomm MDM9x15 and MDM9x30-based MC73xx and MC74xx modules. The document explains the different enumeration states, the reasons for entering said states, and how the host can exit these states.

The AirPrime EM and MC74xx modules support the AUTO-SIM feature wherein the module will select the correct FW+ carrier PRI to use with the detected SIM. This feature is intended for use with the module when the host application does not wish to perform management of FW image switching.
