FAQs /

How do we enable basic standalone GPS tracking with the SIMcom cellular modules that include GNSS tracking feature?


The SIM7100 series, SIM7500 series SIM7600 series and SIM7600 -H series cellular modules that include a GNSS tracker can be used to acquire current accurate location data with and active or passive GNSS antenna connected to the module.

Details of the available AT commands related to GNSS functionality are described in the AT command reference manuals under GPS section. The AT command reference manuals can be found under our product web pages under technical documentation tab.

Depending on if an GNSS antenna with or without low noise amplifier (active/passive antenna) are used, the AT+CVAUXV and AT+CVAUXS command can be used to adjust if the antenna power supply of 3 VDC should be enabled or disabled on the GNSS antenna connector.

Module configured for active GNSS antenna with 3VDC power supply enabled directly from module:

Module configured for passive GNSS antenna and antenna voltage supply from cellular module is disabled:

A basic standalone GNSS tracking session outputting the location data on the dedicated NMEA virtual serial interface can be started with the following AT command:

Other useful commands:
(Please note that GNSS configuration parameters can only be changed when tracking is not active)

Stop ongoing GNSS tracking:

Clear GNSS fix related data stored in module:

Set minimum accuracy threshold in meters for location fix (default value 50 meters):

Enable autostart of GNSS tracking at module start up:

The latest GNSS fix can also be requested by AT command:
And the output is in the form:
+CGPSINFO: [lat],[N/S],[log],[E/W],[date],[UTC time],[alt],[speed],[course]

For details on how to configure the GPS for different application and scenarios, such as using Assisted GPS, or changing output formats etc. please relate to the AT commands reference manuals for the specific SIMcom module.

We cannot acquire an DHCP address over qmi_wwan driver when using Raspbian Linux OS?


Raspbian uses dhcpd to probe all available network interfaces found in the system, which is problematic for the qmi_wwan driver interface, if it is done before being configured properly when using cellular modules supporting only Raw-IP.

This can be avoided by setting dhcpd to deny the related cellular module network interface (most often named wwan0 by the system).
Add to the /etc/dhcpcd.conf file in Raspbian the following line (in the end):
denyinterfaces wwan0

Now, restart the system (preferably re-power it) so cellular module fully restarts also.

At next startup, the settings should be applied and you can now configure and use the qmi interface as described in some of the others faq's, found on the Techship webpage.


How can we use the Simcom SIM7000 series with ECM network interface over USB in Linux systems?


In the recent firmware releases for the Simcom SIM7000 series it is possible to take advantage of the ECM network interface type over USB in order to establish data connectivity to host system instead of using Modem/PPP protocol or QMI. This how-to FAQ shows how it can be done.

The Simcom SIM7000 series expose a set of serial and QMI/RMNET interface over USB in default configuration.
By sending command:

The USB QMI/RMNET network interface can be configured to become a ECM interface instead. If this is supported in your current firmware version the module will re-enumerate in the host system with a ECM interface.

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:
Restart module:

The module will restart now and appear in system with the following USB IDs:

If the option driver is not attached initially it can be done so by force loading the driver:
modprobe option
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: IPV6, 2a02:aa1:1018:5fc2:b532:a78c:7e20:fedb, , 2a02:aa0::55, 2a02:a6

In Linux you should now run a DHCP client on the network interface in order to acquire an IPV4 adress:
dhclient -v enp0s20u2

How-to use automated connection establishment with SIM7600E-h when using RNDIS USB mode


Both Windows and Linux systems can support RNDIS host drivers for the SIM7600 series modules, this example is done in Linux. There is a open source Linux in-kernel driver supporting rndis host USB endpoints called rndis_host.

By default the Simcom modules are delivered with QMI/RMNET interface enabled, so you will have to change the default USB mode with AT command on the Modem/AT serial ports available over USB.
Bus 001 Device 006: ID 1e0e:9001 Qualcomm / Option

Switch from 9001 to mode 9011 for RNDIS:
The module should restart automatically and re-enumerate with the new USB IDs
Check with lsusb that you have the Simcom SIM7600 module loaded, VID PID value: 1e0e 9011
Bus 001 Device 006: ID 1e0e:9011 Qualcomm / Option

Verify with lsusb -t that the Linux in-kernel driver rndis_host or cdc-ecm drivers are loaded correctly for interface 0 and 1.
It can look e.g. like this:
lsusb -t

/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 480M
|__ Port 4: Dev 6, If 3, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 1, Class=CDC Data, Driver=rndis_host, 480M
|__ Port 4: Dev 6, If 6, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 4, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 2, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 0, Class=Communications, Driver=rndis_host, 480M
|__ Port 4: Dev 6, If 5, Class=Vendor Specific Class, Driver=option, 480M

If your system don't load the option serial interfaces correctly, then they can be forcefully loaded as bellow:
modprobe option
echo 1e0e 9011 > /sys/bus/usb-serial/drivers/option1/new_id
See the following Linux kernel commit for details on how to modify the option.c driver in order to auto load the driver:
USB: serial: option: add support for Simcom SIM7500/SIM7600 RNDIS mode

For the modules network connection and interface to automatically activate you should have the SIM PIN deactivated or script it so host system provides it to module at every startup.

A APN name provided by the network carrier which is used to establish a packet data connection to the cellular network is required. If you define a empty string as its default value, will make the module try to subscribe for correct APN name from network, however this works in many cases but not always. If so it has to be configured with commands as bellow:

Check configured APN profiles:
You should have minimum the following defined to have module try request details from cellular network:
+CGDCONT Profile 1 is used for cellular network registration and profile 6 for the RNDIS network interface data connection.

Define both APN profiles according to the details you have obtained with your cellular subscription. Most often the APN details are same for both registration and data connection, define them to profile 1 and 6.

Some APN names require additional authentication also, please refer to the AT command: AT+CGAUTH in the AT commands guide on how to define it correctly. Current auth configurations can be checked with command:
Most often no auth details are needed for the profiles and they should be empty, profile 1 can be cleared with command:

If you have modified the APN information, username and passwords it is needed to re-attach to the packet switched network or re-register in the cellular network to activate the new settings. It can be done e.g. with AT+CFUN=0 command followed by AT+CFUN=1 to switch module operation mode (SIM card will be re-initialized also so PIN code have to be given again if PIN check activated).

The module will now establish the data connection according to the new settings.

If everything is working correctly and connection established you can now run a dhcp client on the network interface.
dhclient -v usb0

Useful Linux kernel configs to have enableb when integrating cellular modules in the Linux kernel


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 either as part of kernel or modules are listed bellow. Many cellular modules base their Linux support on these, either supported out-of-the-box or by applying source code modifications to them.

Configs for USB serial drivers:

Configs for Modem/PPP support:

The importance of using multiple antennas on LTE and 3G cellular modules


When designing in an LTE or 3G cellular module, using two antennas always offer the best possible signal reception and module performance. For LTE modules, usage of two antennas are mandatory if you want to take full potential in terms of signal quality and downlink data throughput.

Using just one antenna will disable the advance signal processing benefits you can achieve with MIMO antenna technology and approximately decrease downlink throughput by half on a LTE Cat-4 capable device. As we move onwards to even higher data throughputs, even more antenna channels will be required. For example, the new LTE Cat-18 Telit LM960 module need four antennas to utilize its full data throughput capabilities with 4x4 MIMO.

Although MIMO is not available on 3G modules, a second diversity antenna will allow the modules signal processors to improve the received signal quality especially in areas with poor reception. To further maximize the antenna performances and get proper isolation between the antennas, you should also preferably position them as far apart as possible and in different polarization.

A preferred alternative is to use a combined antenna instead of including several antenna elements. These antennas can combine different MIMO/diversity configurations with other RF elements, e.g. GNSS and Wi-Fi and are also available in different forms and mounting options.

Having everything combined in a single antenna unit also eases the installation and decreases the mounting space as well as passthrough holes required, essential for example when installed on a vehicle roof.


Our cellular module, Huawei ME909s series miniPCIe, is not detected in the MikroTik RouterBoard embedded board running RouterOs, what can we do?


Many host systems running e.g. operating systems like Linux have a very short detection time for peripheral USB devices on the internal miniPCIe sockets before the host system continues to load.

This can result in the cellular module not being detected at all in the host system due to the cellular modules internal boot-up procedure have not yet finished. The D+ signal will be pulled high first after the modules internal boot-up process have completed and then signal its device presence on the USB interface to host system.

When you intend to use a cellular module in these systems and the cellular module cannot be detected, please try to add in a delay to the host systems boot-up procedure in the earliest possible stage, this to allow the cellular module to boot-up correctly first and show its presence to host system before it have passed the peripheral devices detection phase.

The boot-up times for the cellular module can commonly be found in the products hardware guide.
For Huawei ME909s series it is approximately 9 seconds.

For example in Mikrotik RouterOS, this often can be the reason for the cellular module not being detected. Then you can try to adjusting the "boot-delay" parameter from its default 1 second.

Please refer to the RouterOS Wiki for further details on boot-up delays and other useful parameters.
