To troubleshoot and solve a technical problem

For this, we do ask you to please provide information about your system and logs from the related module when creating a technical support ticket.

When creating a ticket, please provide a detailed description of what the exact problem is and what precise situations it is present in.

Then, please provide the following information about your host system:

Hardware (system board, peripherals…)
Operating system and detailed versions (E.g. Windows, Linux dist, release, kernel…)
Driver and driver versions
Cellular connection provider

Specific module information, which is found on the label:

Model
SKU/BOM or P/N code
IMEI number

If you are running on a Linux-based system, please capture the terminal logs below:

uname -a
lsusb
lsusb -t
ifconfig -a
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
dmesg

To gain insight into the settings done on the device, please collect the following AT-command output from the module; some commands are specific to a specific type of module, and all commands may not provide an output other than error, but most should provide a response.
