Command format:

1

 

  • Searching network steps:
AT+NBAND?//QueryBand
AT+CFUN?//value :1
AT+CIMI//Query IMSI number
AT+CSQ/Query the signal strength
AT+NUESTATS//Query module status
AT+CGATT?//Back + CGATT: 1 indicates that the attachment is successful, with a delay of about 30s
AT+CEREG?//Search for network status, 1 for Internet, 2 for Network
AT+CSCON?//Query the connection status, 1 CONNECT, 0 IDLE
  • Manually configure network if fails to register network automatically:
AT+CFUN=1 AT+CIMI//Execute CFUN = 1, wait for 4 seconds to query IMSI, if it can be found that the card has been identified;If not, please check the card is inserted and confirm whether it is a USIM card.
AT+NBAND?//Query frequency band information.
AT+CEREG=1//Set to automatically register network registration status, when the module registered on the network, will report URC.**AT+CGDCONT=1,“IP”,“APN”**//The APN is configured locally \(or not configured\) for local access.
AT+COPS=1,2,"46000"**//Specify PLMN search, PLMN configuration.
AT+CSQ//Query signal strength.
AT+NUESTATS// Query module status
AT+CGATT?//Back + CGATT: 1 indicates that the attachment is successful, with a delay of about 30s
AT+CEREG?//Search for network status, 1 for Internet, 2 for Network
