The SIMCOM SIM8230G-M2 is a 5G RedCap module based on 3GPP Release 17, designed for power-efficient mid-speed applications. It supports 5G SA (Standalone) mode and LTE Cat 4 fallback, with reduced bandwidth and lower complexity, making it ideal for IoT and industrial use cases
Monogoto SIM
SIMCom SIM8230G-M2 5G RedCap cellular modem
Access to a private network
Connect to the modem, enter the command: AT and wait for the response: OK
Reset the modem to the factory default configuration:
Set the error reporting to verbose, resulting in more descriptive error messages (optional):
Check if the SIM card is attached and is not locked with a PIN, expected response: +CPIN: READY:
If you receive an error, the SIM may not be inserted properly or the SIM is protected with a PIN. By default, Monogoto SIMs are not PIN protected.
Request the modem hardware version:
Request the modem firmware version:
response:
Request the IMSI (International Mobile Subscriber Identity):
Request the ICCID (Integrated Circuit Card ID), which is the identification number of the SIM card
Manually set the preference mode:
AT+CNMP=71 → Enables 5G NR along with LTE, UMTS, and GSM (multi-mode operation).
AT+CNMP=13 → Typically enables LTE/UMTS/GSM only (no 5G).
To test if the network is set correctly enter:
Expected response: +CNMP:71
Manually set the IMS disable
Manually set the network:
Monogoto's private LTE network is indicated with the MCCMNC code: 99974. To connect to the private LTE network, enter:
To test if the network is set correctly enter:
Expected response: +COPS: 0,0,"Monogoto5G 99974",11
11 indicates that the modem is using 5G SA.
Check the radio signal strength and signal quality:
Example response: +CSQ: 22,1
Set the APN to data.mono:
To test if the APN is set correctly, enter:
Expected response: +CGDCONT: 1,"IP","data.mono","0.0.0.0",0,0,0
Activate the PDP (packet data protocol) context:
Test if the PDP context is activated:
Expected response: +CGACT: 1,1
Example response:
99974 (the fourth value) indicates that the device being connected to Monogoto's Private LTE Network
78 represents the cellular band the modem is currently using
Expected response: +CGPADDR: 1,10.XXX.XX.XXX
A PING test can be performed to test if the modem has an active data connection with a mobile network.
When cellular modems are idle for a long period of time, cell towers might drop the data connection to save resources. Sending regular PINGs is a good method for testing the data connection, as well as for keeping the connection alive because the operator registers your device as being actively used.
Send 4 PINGs to IP address Google:
Example response:
When using Windows, using the disk or USB stick provided by Simcom.
