Query device information
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 SIM card
Network Configuration
It is possible to let the modem select the network automatically, or to manually define a network to connect with.
Option 1: Automatic Network Selection
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:
0 indicates 2G
2 indicates 3G
7 indicates 4G
Option 2: Manual Network Selection
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:
To find which of the networks Monogoto has roaming agreements with, review the Coverage lists.
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. It is possible to leave the value for setting the cellular technology out, allowing the modem to select the RAT by itself.
Check the radio signal strength and signal quality:
+CSQ returns 2 values separated by a comma. The first value represents the signal strength and provides a value between 0 and 31; higher numbers indicate better signal strength. The second value represents the signal quality indicated by a value between 0 and 7. If AT+CSQ returns 99,99, the signal is undetectable or unknown.
Define the cellular band(s) (optional)
It is possible to lock the modem to specific bands for specific technologies. This may result in a faster boot cycle as the modem does not need to scan for available bands at startup.
To read the available options, enter:
Expected response:
To lock the modem to European bands, enter:
Query Network information
Return the operational status, including the Radio Access Technology (RAT) and band used:
Example response:
Network Activation
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
Validate if your device received an IP address:
Expected response: +CGPADDR: 1,XX.XXX.XX.XXX
Do you see an IP address? Congratulations! You’ve successfully connected the Sierra Wireless modem to Monogoto 🎉
