The Type 1SC module is the world’s smallest Cat. M1/NB-IoT module with global certification. It supports GPS/GNSS, OpenMCU, and Integrated SIMS.
Monogoto iSIM profile
Reset non-volatile memory:
Reboot module:
Set the error reporting to verbose, resulting in more descriptive error messages (optional):
Check the status of the SIM card. The correct response should be: +CPIN: READY
+CPIN: READY means that the iSIM is ready for use and does not require any PIN entry.
Request the product type, hardware, and firmware version:
Request the IMSI (International Mobile Subscriber Identity):
Request the ICCID (Integrated Circuit Card ID), which is the identification number of the iSIM
Check the SIM initialization selection policy is currently using:
Expected response: SIM_INIT_SELECT_POLICY:5. The last digit indicates the Active SIM:
0 indicates External (SIM card)
5 indicates Internal (iSIM)
It is possible to let the modem select the network automatically or to manually define a network to connect with.
To set the modem to automatic network selection enter the command:
Check the network and cellular technology the modem is currently using:
Expected response: +COPS: 0,0,"<name of operator>",X. The last digit indicates the cellular technology:
7 indicates LTE Cat-M1
8 indicates NB-IoT
Start with searching for available networks:
It may take several minutes before the modem responds.
The modem responds with the names and the MCCMNC codes of the available networks. It also shows the cellular technologies the networks support:
Check the network and cellular technology the modem is currently using:
Expected response: +COPS: 0,0,"<name of operator>",X. The last digit indicates the cellular technology.
Manually set the network and the cellular technology:
Replace XXXXX with the MCCMNC code of your operator, for example"20404" for Vodafone NL. Use 7 for LTE Cat-M1.
Check the radio signal strength and signal quality:
It is possible to lock the modem to one or more specific bands. This may result in a faster boot cycle as the modem does not need to scan for available bands at startup.
Although the modem may support many different bands, your local network operator may not. Have a look at the LTE Cat-M1 overview to find the available band(s) in your region.
To lock the modem to a specific band, a hexadecimal value representing the band needs to be sent to the modem. To lock the modem to LTE-M band 5, send:
To test if the band(s) is properly set, enter the command:
Example response: Bands: 1 ,2 ,3 ,4 ,5 ,8 ,12 ,13 ,14 ,17 ,18 ,19 ,20 ,25 ,26 ,28
They represent the LTE-M bands and NB-IoT bands.
To information about the technology used, the network provider, and the cellular band, enter:
Example response: %MEAS:Signal Quality:RSRP= -115,RSRQ= -15,SINR= -3,RSSI= -120.
Set the APN to data.mono:
Validate if the APN is set correctly:
Expected response: +CGDCONT: 1,"IP","data.mono","0.0.0.0",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
Expected response: +CGPADDR: 1,XX.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 5 PINGs to the IP address 8.8.8.8:
Example response:
