SIM7080G not finding any networks

Hello, I recently moved from SIM800L to SIM7080G because this supports networks over 2G. I was able to use my SIM800L and hologram SIM Card to register in the network but now I need to be able to connect to networks above 2G thus I got a SIM7080G, I am using the same SIM Card but I haven’t been able to get the SIM7080G to find any networks.

This is what I tried in the SIM7080G, can anyone help?

CSQ of 99,99 suggests bad antenna, or bad antenna connector, etc…

Hmmm…maybe try this: AT+CFUN?

Should get a “1” back. If so, check out antenna, etc…

If you get back something else other than 1, then enter: AT+CFUN=1

Then try again to connect.

Depending on the setting, that CFUN can turn off both transmit and receive circuits. The “1” turns them back on.

This is what i put together for ftp using an sim7000A, it hopefully will be a similar process to your sim7080G.
If you aren’t using ftp you only need to go as far as AT+SAPBR=1,1 which opens a TCPIP tunnel for data communications.

AT+CPIN? //Check for sim card ready status

AT+CGDCONT=1,“IP”,"" //configure ip address connection type

AT+CSQ //Check signal strength

AT+CGATT? //Check attachment

AT+CGNAPN //Checks if the cell tower provided APN settings for the provider (sim card owner ie hologram.io)

AT+COPS? //Check what operator we are connected to (confirms connection to provider/sim card owner ie hologram.io)

AT+CNACT=1 //Opens PDP connection (provides ip address)

AT+CNACT? //Confirms PDP connection by revealing current ip address

AT+SAPBR=1,1 //Opens a IP tunnel inside the sim7000, allows FTP use

AT+SAPBR=2,1 //Confirms open tunnel by showing current ip address

AT+FTPCID=1 //Sets FTP configuration to bearer 1.

AT+FTPSERV=“FTPSERVER” //ftp server

AT+FTPPUTNAME=“test.txt” //name of file

AT+FTPPUTPATH="/" //path of file

AT+FTPPUT=1 //Attempts to connect to the FTP server, Must wait for response, example: +FTPPUT: 1,1,1360 The last number is how many bytes you can send in one upload.

AT+FTPPUT=2,10 //Send 10 bytes of data

AT+FTPPUT=2,0 //Close connection to FTP server
