Reset the modem to its default configuration:
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
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 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
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:
0 indicates 2G
2 indicates 3G
7 indicates 4G
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.
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:
Return the operational status, including the Radio Access Technology (RAT) and band used:
Example response:
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
