BG95-M3 Open PDP context failed

IoT Modules LPWA Module
1

Hi,

I’m trying to use the module with a 2G SIM that was working before, but now after getting a valid IP and trying the ping command I get the following response:

+QPING: 561 (Open PDP context failed)

The sequence of commands is as follows:

AT+CFUN=4
OK

AT+QCFG=“nwscanmode”,1
OK

AT+QCFG=“nwscanseq”,01
OK

AT+CGDCONT= 1,“IP”,“my-APN”,“0.0.0.0”,0,0
OK

AT+CFUN=1
OK

AT+COPS=1,2,“my-OPER”,0
OK

AT+CREG?
+CREG: 0,1

OK

AT+CGACT=1,1
OK

AT+CGPADDR=1
+CGPADDR: 1,10.2.184.45

AT+QPING=1,"www.google.com.uy"
OK

+QPING: 561

AT+CGDCONT?
+CGDCONT: 1,“IP”,“my-APN”,“0.0.0.0”,0,0,0

OK

I used the same SIM with a BG96 and it’s working fine, any tips on what might be the issue?

Best regards,

Edu
