How-to change the cellular modulesUSB composition mode to Mobile Broadband Interface Model (MBIM) used by Windows 8 and 10 systems for controlling and establishing data connectivity through the built-in connection manager in Windows?
This is done by sending a set of AT commands to the cellular modules Modem or AT serial interface found in Windows Device Manager. Please see list below for associated AT commands.
(For additional details, refer to the product specific software, ports, and AT commands guides found on the Techship product web pages under technical documentation tab).
After the AT commands have been received by the module and has restarted, the USB interface endpoint composition should have changed to include MBIM interface as well.
You can find the correct Serial COM port number by checking Windows Device Manager, under the Modems drop down -> (right click and see properties for selected COM port info) or under the Ports (COM & LPT) drop down.
Vendor specific commands to use:

Please be aware that some USB mode configurations do not include any serial interfaces, making it impossible to revert the changes using AT commands.
How to collect initial diagnostics data for Gosuncn ZTE WeLink cellular modules when requesting 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 cellular module when creating a technical support ticket via Techship.com.
Include a problem description of what exact problem is and in what precise situations it is present/occurring.
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 the cellular module found on product label:
-SKU/BOM or P/N code
(For RMA returns the IMEI number is also required)
If you are running on a Linux based system, please capture the terminal logs bellow:
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
The log output requested from the commands bellow, can be acquired from the module by accessing one of the USB enumerated serial (COM) interfaces accepting AT commands. (In Windows this is generally found listed as a Modem interface or AT commands serial interface in the device manager and in Linux it is usually found on some of the /dev/ttyUSB* interfaces). Send the following commands to module and capture the text output and include them when creating the the technical support ticket.

What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?
Most cellular modules can be supported in Linux by using som of the in-kernel drivers. The physical data interface to the host Linux system is usually done over USB which enumerates a set of different endpoints/interfaces. A set of serial interfaces for Modem/PPP, AT commands, NMEA location data and chipset debug information are almost always available in all configurations.
In addition some type of network endpoint/interface are also available and exposed. This can vary between manufacturers and chipset vendors and can also commonly be configurable by using USB configuration mode switching or through vendor specific AT commands.
Recommended kernel configurations to enable are listed bellow. Many cellular modules base their Linux support on these modules and drivers. Once included in the kernel build, the USB interfaces will be detected and bound correctly out-of-the-box or after applying source code patches to the driver modules.
Configs for USB serial drivers:
Configs for Modem/PPP support:
Configs for USB network drivers:
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.

How can we activate and use dual stack IPv4 and IPv6 functionality on the Gosuncn ZTE Welink ME3630 series cellular modules in Linux?
This can be done by configuring and using the Gosuncn ZTE Welink ME3630 module in Linux the following way:
Check with AT commands that you are using the most recent firmware version on the cellular module:
ME3630E1CV1.0B19 [Jan 15 2019 16:03:19]
The module have to be switched from default USB mode in order to support this, in this mode it uses RNDIS interface and drivers instead in host.
This mode can be switched with AT commands:
The module will restart now and appear in system with the following USB IDs:
T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=03 Dev#= 9 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=19d2 ProdID=0601 Rev=03.18
C: #Ifs= 5 Cfg#= 1 Atr=a0 MxPwr=500mA
I: If#=0x0 Alt= 0 #EPs= 1 Cls=e0(wlcon) Sub=01 Prot=03 Driver=rndis_host
I: If#=0x1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=rndis_host
I: If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#=0x3 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=option
I: If#=0x4 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=option
If the option driver is not attached initially it can be done so by force loading the driver:
echo 19d2 0601 > /sys/bus/usb-serial/drivers/option1/new_id
Activate the network interface in the Linux host system (check e.g. with dmesg what system named it to):
ip link set enp0s20u2 up
Make sure you have a cellular subscription and APN that allow usage of IPV4 and IPV6 functionality combined.
Default configuration with setting a empty string lets the module subscribe for an APN from cellular network:
With defined APN:
If you have to modify/set AT+CGDCONT, please re-register in cellular network e.g. by toggling:
(Enter PIN again with AT+CPIN if necessary)
Check that you are registered in the cellular network and module are attached on packet switched network and have got an IP:
Now start the network interface data connection:
With empty string APN details in second parameter, then module try to request them from network:
Or with APN defined:
You should receive bellow if successful:
Check the status of the network interface activation, both IPV4 and IPV6 information should be listed as bellow if successful:
+ZECMCALL: IPV4, 22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206

In Linux you should now run a DHCP client on the network interface in order to acquire an IPV4 adress:
dhclient -v enp0s20u2
Listening on LPF/enp0s20u2/56:60:35:1b:9f:7f
Sending on LPF/enp0s20u2/56:60:35:1b:9f:7f

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".
