IPhone 14 pro max data connection issue

I recently bought an iPhone 14 pro max. It was randomly dropping the data connection to my cell service. All online services (Whatsapp, Messenger, etc) failed to connect to the internet, Even though the cellular strength indicator showed 4-5 bars. I can only access the internet after restarting my phone. I tried

1. turning data/airplane mode on and off also didn’t work.
2. Check for a Carrier Settings update.
3. Reset ESIM profile
4. Reset my Network Settings

The only workaround I could find was power off/on. Please assist this issue as it is a headake
