[Note]: You must use a SIM card with GPRS networking function enabled and not out of service.
NDIS Dail-up
- At present, when using Windows 10 operating system, you can connect to 4G DONGLE module (equipped with 4G card of China Mobile/Telecom/Unicom). After installing the driver, most computers will automatically connect to the Internet.
- If WINdows cannot access the Internet, you need to manually start NDIS dialing, open SIM7600 AT port, and send the command:
AT$QCRMCALL=1,1+enter
At this point, the NDIS dialing takes effect, and the computer can connect to the network; if the dialing command returns an error, send the following command to set the NDIS dialing mode and then dial again:
AT+CUSBPIDSWITCH=9001,1,1
RNDIS Dial-Up Internet
In addition, dial-up Internet access using RNDIS is also possible:
- After the device installed SIM card and antenna, connect the USB port to computer, then connect the power supply.
- Refer to the above to install the USB driver
- Open the serial port assistant, find the serial port number corresponding to the AT serial port, and send the AT command to check whether it is registered on the network:
AT+CPSI?
- If you have successfully registered on the network, then send the AT command to enable USB dial-up Internet access:
AT+CUSBPIDSWITCH=9011,1,1
- If the transmission is successful, the DTU will return OK and reboot automatically.
- And then you can find that there are some unrecognized devices in the Device Manager on the computer, such as RNDIS (with exclamation mark).
- Right-click the 'RNDIS', search "Update Divers" and select "Let me pick from a list of available drivers on my computer", then select "Network adapters" from the device list.
- Select "Microsoft" in the manufacturer list of the Network adapters window, and then select "Remote NDIS Compatible Device" in the list on the right, which is the remote NDIS compatible device.
Click 'Next' and wait for the installation to finish, the RNDIS Kitl device will be installed successfully. And then you can see that the PC can access the Internet via DTU.
PPP dial-up
If the NDIS or RNDIS dial-up cannot access the Internet, you can also use PPP dial-up. The operation steps are as follows：
- Network and Internet Settings -> Set up a new connection -> Connect to the Internet -> Dial up (D) -> Dial a phone number (D): *99# (others are empty by default) -> Connection -> Register -> Connected to the Internet

FAQ
Support SIM standard (Standard) card, as shown in the figure below, if it is Micro or Nano card, you need to add a card sleeve.
In this case, it may be that you have not successfully connected to the network, you can follow the steps below to troubleshoot:
1. First check the hardware connection:
- Check if the MAIN antenna is well connected;
- Whether the connected SIM card can call and surf the Internet normally on mobile phones and other devices:
- If the Raspberry Pi is connected, whether the module enters airplane mode;
2. After confirming that there is no problem with the hardware, the software can use these instructions:
- Check whether the sim card is in good contact: AT+CPIN?
- Check if the network mode setting is correct: AT+CNMP?
- Check the signal quality of the current environment: AT+CSQ
- Check the operator's access situation: AT+COPS?
- Check the connection status: AT+CPSI?
- Check whether it is successfully registered to the network: AT+CGREG?
This problem is generally caused by poor contact between the SIM card and the SIM card socket of the module.
It may be that the APN has not been obtained. Generally, the APN can be obtained automatically. In some areas (IoT card), it needs to be obtained manually. For example, it can be set by the following instructions:
AT+CGDCONT=1,"IP","CMNET" //CMNET is the apn of China Mobile, which is different for different operators
- Generally, the default configuration of SIM7600 is to automatically select the network standard, and it is likely to choose 2G Internet access; if you need to force the use of 4G mode, you need to enter the following AT command configuration:
AT+CNMP=38 //Fixed 4G LTE, if there is no local 4G coverage, you may not be able to register to the network
.png)
- If 4G has been fixed, the speed is still not ideal, it may be a frequency band problem;
AT+CNBP? //Back up the current frequency band (the returned frequency band information can be copied to notepad, etc.)
AT+CNBP=0x0002000000400183,0x000001E000000000,0x0000000000000021 //After returning OK, measure the speed
AT+CNBP=0x0002000004400180,0x000001E000000000,0x000000000000003F //If the speed does not improve, try this
.png)
1. Pay attention to check the device manager, the new device will be prompted during the upgrade process, and there will be no device driver during the first upgrade;
2. Pay attention to the USB cable. The speed of the USB cable is higher during the upgrade process. You need to choose a better quality USB cable to avoid poor contact.
3. You need to run the upgrade tool with administrator privileges (SIM7500_SIM7600_QDL V1.41 only for Update)
4. Uninstall and reinstall the upgrade tool (SIM7500_SIM7600_QDL V1.41 only for Update)
5. For more operation details, please refer to this video: https://www.waveshare.net/wiki/SIM7600-Firmware-upgrade-Video
If the short message is stored in the SIM card, usually 50 is the upper limit. You can use the command: AT+CPMS? Make a query
Using USB 5V power supply, after successful networking, the current is generally in the range of 50~300mA, with an average of about 150mA (for reference only, it depends on the network environment and the working status of the network.
Turn on at the same time, average value: 110~170mA
- Frequency: 700m 800m 900m 1710-1920M 2010-2100M 2300-2400M 2500-2690M-5800MHZ
- Gain: 9dbi ± 0.7dbi
Question:NDIS dial-up of SIM7600X module fails and the driver cannot be installed, what should I do?
- Make sure your system kernel is above 5.4. Do not use sudo update to upgrade the Raspberry Pi to the latest version. This will upgrade the kernel version to a version higher than the current firmware and it will not be recognized.
- It is recommended to use the more convenient RNDIS dial
- Can burn the latest Raspberry Pi Raspbian system, reconfigure NDIS dial
It is recommended to use the more convenient RNDIS dial
