JIO SIM card not registering to network on EC200U-CN module

QuecPython
1

Hi ,I am working on a project using EC200U-CN module. I was using Airtel SIM card to connect to network and make socket communication using QuecPython. When i tried JIO card the checkNet.waitNetworkReady(), function returns (2,2).
I checked SIM state and sim is fine.
The received signal strength is -98dBm.
The card is working fine and connects to internet when put in mobile.
I changed APN settings to JioNet too.

HI, vishak

According to the command, the module is not netted successfully. Have you ever captured the log of the module before? it may require log analysis of the problem

I am also having the same issue. It works with airtel and Vodafone fine.
I can provide you the logs, just tell me how to do it using the watcher?
