We are issuing the following commands but cannot establish a connection:

-\> AT+KCNXCFG=1,“GPRS”,“m2minternet.apn”  
\<- OK  
-\> AT+KTCPCFG=1,0,“8.8.8.8”,80  
\<- +KTCPCFG: 1

OK  
-\> AT+KTCPCNX=1  
\<- ERROR

Any idea what we are doing wrong?  
Thanks

Hi,  
1st step should be to activate Termination Error  
Send `AT+CMEE=1` in order to replace `ERROR` response by a `+CME ERROR: x` with x a number which meaning is indicated in the AT command user guide
