Mobile data not working after certain period of time in iPhone 14 Pro Max

Mobile data not working after certain period of time. I tried to turn on & off Airplane Mode / Mobile Data, But didn't work.

It worked when I restart the phone / reset my network settings, But again the issue comes back after some time.

NOTE:

• Sim working fine,I can make normal calls.
• Phone shows 4G but only internet is not working.
• Wifi working fine without any issues.
• iOS is UpToDate - iOS 16.3.1.
• Nothing wrong with carrier or my internet plan.
