Mobile network LTE is not working

[mayur-mb]

I have enabled mobile data, roaming is also enabled as my SIM is in roaming state. In preferred network 4G is selected. I can also see 4G in the status bar near network symbol. But there is an "X" in the network symbol as well. When I try to test ping it says network is unreachable. I tried different APN settings also. Still same result.

If I use *#*#4636#*#* in that

Voice Service: In Service
Data Service: Connected
Data Network Type: LTE
Voice Network Type: LTE

Even if I switch to 3G it shows same result.

In adb logcat I am get this logs

I am working in Android 9.0 background with a LTE module. It is running stock android with WiFi disabled and only mobile network is enabled.
