How to change USB composition mode to Mobile Broadband Interface (MBIM) that is used by Windows 8 and 10 systems for data connectivity and enabling support for the built-in connection manager in Windows?
This is done by sending AT commands to the Modem or AT serial interfaces that are accepting AT commands and changing the USB endpoint composition:
Sierra Wireless EM74xx, MC74xx series module:
Sierra Wireless EM73xx, MC73xx series module:
Simcom SIM7xxx series modules:
ZTE Welink ME3630 series:
Telit LE910x V2:
On Huawei modules the USB mode changing is done automatically by the Windows drivers and otherwise defaults to the modules standard endpoint interfaces.
How to collect initial diagnostics data and logs for Telit cellular modules needed when requesting Techship technical support?
Solution: In order to troubleshoot and solve a technical problem, we ask you to please provide information about your system and logs from the related Telit module when creating a technical support ticket.
Problem description of what exact problem is and in what precise situations present.
Describe the host system:
-Hardware (system board, peripherals...)
-Operating system and detailed versions (E.g. Windows, Linux release, kernel...)
-Drivers and driver versions
Identify the precise details of cellular module found on label:
-SKU/BOM or P/N code
(For RMA returns the IMEI number is required also)
The logs from module firmware can be acquired by accessing one of the USB enumerated serial (COM) interfaces accepting AT commands. (In Windows this is generally modem devices or AT commands serial interfaces). Send the following commands to module and capture the text output and include them when creating the the technical support ticket.
Verbose error reporting:
USB endpoint configuration:
Serial port configuration:
Selected network access techniques:
List network operator info:
Network registration status:
Last serving cell network information:
Current network status:
List APN details:
Attach UE to default PDP Context:
List default data connection details:
List IP addresses:

Why should we use USB3 instead of USB2 as host system data interface if the cellular module can support both?
Cellular modules supporting higher data throughput rates like LTE Advanced, category 6 and above (300Mbps downlink and 50Mbps uplink) often support both USB3 interface as well as USB2 interface towards the host system.
It is recommended to implement and use the USB3 data interface rather than the older USB2 interface on these modules between host system and the cellular module. This because USB3 can support around 10 times higher data throughput rate compared to USB2 and avoid a possible bottleneck / limitation in the data interface between host and cellular module.
If a miniPCIe based cellular module implementing USB3 are used, please verify that conflicts don't occur towards your hosts miniPCIe socket, as the USB3 interface is not implemented by default in the miniPCIe standard and therefore signal collisions can happen between USB3 pins and PCIe data interface pins situated on same locations. Refer to the cellular module hardware guides and host system hardware guides to verify this.
How can we establish data connection for cellular modules in Windows 8 and Windows 10 systems?
Microsoft Windows desktop versions starting from Windows 8 and newer have built in data connection manager for WWAN, Wifi etc. that can be used to configure, control and establish the data connection of cellular module that support MBIM interface, which most cellular modules do.
The connection managers settings and controls can be found and accessed on Windows desktop start menu through the network icon (see picture).
The Cellular tab can be found in Windows system settings and if needed the connection APN details can be manually entered through "Advanced options".
