 Answer:

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?

 Answer:

Restart SIM7600E-H after sending the following commands:

AT+CGPSNMEAPORTCFG=3
AT+CGPSNMEA=197119
AT+CGPSINFOCFG=10,31



 Answer:

This problem is generally caused by poor contact between the SIM card and the SIM card socket of the module.


 Answer:
The reason is that the echo is not turned on. SIM7600X can send the following command and press Enter, and the echo is successfully turned on after the display is OK.

 Answer:

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","APN" //The APN of different operators is different, here the APN is changed to the corresponding operator, for example:
China Mobile APN: CMNET; China Unicom APN: 3GNET; China Telecom APN: CTNET
SIM7600X apn.png


 Answer:

It can be set by the following commands:

AT+CGDCONT=1,"IPV6","APN" //Switch to IPV6, the APN of different operators is different, pay attention to distinguish the settings
AT+CGDCONT=1,"IP","APN" //Switch back to IPV4


 Answer:
  • No APN is set, configure APN as described above.
  • After being banned, high-traffic (real-name IoT) cards are bound by chance cards and can only be used on one device (Ministry of Industry and Information Technology, Ministry of Public Security, must be issued to operators); The operator checks the status of the card and unlocks it.


 Answer:

The VOLTE function can be turned on with the following command:

 at+voltesetting=1
 at+cnv=/nv/item_files/modem/mmode/ue_usage_setting,1,01,1

The VOLTE function can be turned off with the following command:

 at+voltesetting=0
 at+cnv=/nv/item_files/modem/mmode/ue_usage_setting,0,01,1


 Answer:
AT+CSCA="+8613800755500"

Command to add + Enter, return OK. Note: China Mobile's SMS service center number is +861380xxxx500, where xxxx is the long-distance telephone area code where you are located. The SMS center may be different from place to place. For details, you can query Baidu or call the customer service of China Mobile Unicom. This SMS center is Shenzhen (0755) ;


 Answer:
  • Confirm that SIM7600X is registered to the network, and confirm that the SIM card can send and receive text messages normally on mobile phones and other devices;
  • Set the correct SMS center number;
  • Initialize SMS settings with the following commands:
AT+CSCS="IRA"
AT+CSMP=17,167,0,0


 Answer:

The AUX antenna can increase the downlink rate: The AUX antenna is also a diversity antenna, which plays the role of receiving signals, improves the signal reception capability, and works with the MAIN antenna to increase the downlink rate.


 Answer:
  • Under normal circumstances, SIM7600X has been automatically dialed after receiving the Windows system, and there is no need to repeat dialing. Repeated dialing will return NO CARRIER
  • If you still can't dial-up Internet access, please use the following command to change to Windows default dial-up Internet access mode
    AT+CUSBPIDSWITCH=9001,1,1 
  • The display is turned off, the mobile network is not enabled, you can ignore it and go online directly;

 Answer:
  • 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

SIM7600X-FAQ (4).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

 Answer:

SIM7600X-FAQ (6).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
