root@ns02-kit:~#

any idea about this
any leads would be appreciated

I cannot found whether the module has been registered the network. Please provide some messages like
AT+COPS?
AT+CGDCONT?
AT+CREG?
AT+CEREG?
AT+CGREG?

I found searched in some other technical forums, I am wonder if you disable the fireware, maybe it will be solved.

thank you for replaying

I found the solution and update my wcdma-chat-connect file I will add some command on the script and its working here is my wcdma-chat-connect file
