EC25 ppp connection failure

I’m using EC25 module for remote monitoring system.

At first ppp connection was normal in qnavicator. Afer working with pdp commands to setup smtp in my code ppp doesn’t dial in qnavicator.

Please anybody facing the same issue

And every first on time of modem cfun will be at 4. I should have to change it to 1. What’s the reason behind this

Hello there
You can execute AT+CGDCONT command and ATD*99# to implement PPP connect, if ppp connect success, you will get IP address. You can attach the step you execute,we will check it.
For cfun value is 4, please check your PC airplane mode is turn on or not.
