I am using 4G GSM EC200U-CN and i am using the sim card JIO 5G sim and there is an error when i select PDP ACT option which is “Fail to activate the context”. Since i am using jio sim card i have access point name given as JIONET.

Could you show that

AT+CGACT?
AT+CEREG?
AT+QENG="servingcell"

Hello These are the replies
AT+CGACT?
+CGACT: 1,0

AT+CEREG?
+CEREG: 0,1

AT+QENG=“servingcell”

+QENG: “servingcell”,“NOCONN”,“LTE”,“FDD”,405,864,610D25,35,1425,3,3,3,90,-104,-10,-79,66,23

  1. When registering LTE, this module does not carry APN by default and uses empty APN to attach;
  2. The APN for activating PDP is inconsistent with the APN sent by the Cellular network, resulting in an error in activating PDP;
    Solution:
  3. AT+QCFG=“dftpdn”[,<ip_version>[,<apn_name>[,<auth_type>[,[,]]]]] Use this AT to configure the default bearer APN; then AT+QICSGP=1,1,“APN”,“”,“”,1 Keep the parameters configured by AT+QICSGP consistent with the default bearer;
  4. Use AT+QICSGP=1,1,“”“,”“,”,1 to use an empty APN. When the module activates PDP (CID=1), the parameters of the default bearer will be used to activate PDP (CID=1);

I have done according to the steps but i still get the error. These are the commands:

AT+QCFG=“dftpdn”,1,“JIONET”,0
OK

AT+QICSGP=1,1,“JIONET”,“”,“”,1
OK

AT+QICSGP=1,1,“”,“”,“”,1
OK

AT+QIACT=1
ERROR

maybe you can try
AT+CFUN=0
AT+QICSGP=1,1,“”
AT+CFUN=1
AT+QIACT=1
The APN should be the default bear APN.
