Thank you
Manoj

1.Check whether the APN configured above is correct.
2.Check whether the user name and password need to be configured for the APN
3.AT+QICSGP=1,2,the"2" indicated as IPv6,Check whether the APN supports IPv6 only,and the network supports only IPv6.
I suggest you refer to the configuration parameters below

AT+QICSGP=1,1,“APN”,“username”,“passowrd”,1
//Ensure that the APN, user name, and password are correctly configured

Thank you
Its working now. Before we missed some network mode configurations.
