Cell tower signal quality

I know that I can typically select more than one network at a given location when using a Monogoto SIM.

Apart from the standard operator selection method (AT+COPS), is there a method that can also indicate the best serving cell tower at the device location?

Hi Jasper,

thanks for reaching out.

Indeed some specific modem manufacturers offer proprietary methods to do very detailed network surveys.

An example for that would be #CSURV series of commands:


response: 'Network survey started ...

earfcn: aaaa rxLev: -46 mcc: XXX mnc: AA cellId: XXXXX tac: XXXXX phyCellId: XXX cellStatus: CELL_SUITABLE rsrp: -82 rsrq: -15 bw: 20


earfcn: bbbb rxLev: -73 mcc: XXX mnc: BB cellId: XXXXX tac: XXX phyCellId: XX cellStatus: CELL_FORBIDDEN rsrp: -113 rsrq: -20 bw: 20


earfcn: cccc rxLev: -96 mcc: XXX mnc: CC cellId: XXXXX tac: XXXX phyCellId: XXX cellStatus: CELL_LOW_LEVEL rsrp: -136 rsrq: -20 bw: 20


Network survey ended'

Note: I have obfuscated some details for security reasons.

What can we get from that? Well, should the MCC/MNC combination of the cell considered CELL_SUITABLE be a supported network that matches your budget then it would be a good choice to select this network using the AT+COPS=1,2,”XXXAA”,7 command at that location.

Unfortunately, this example is not universally applicable but other modems may provide equivalent or similar capabilities that would allow you to scrutinise the RSRP & RSRQ values measured by your modem. Please consult the respective AT command reference for further information.

Hope that helps!


Thanks Frank, this is useful. I will try this out and get back to you if you have any further questions
