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

This legacy issue tracker isn't in use anymore. You should file GrapheneOS issues at https://github.com/GrapheneOS/os_issue_tracker but from what you've written it seems to be about something else.
