iPhone 15 pro lag and constant disconnection

So I’ve been having this problem even on the previous iPhone 12 so I thought maybe updgrading the phone would just solve everything which looked like it for the first few days but it came back

So basically my phone would just randomly start losing connection no matter if it’s data or WiFi and this problem would constantly persist for a while then it would go back to normal.

This lose of connection is often accompanied by some lag when I click the settings app and the app would be just grey blank or just when I click WiFi and data it would just start freeze for a while or it just says no sim in the data section and the hotspot option would disappear for a while until the problem goes away

The problem is when this starts it would constantly lose connection and regain it back and forth which is pretty annoying.

It seems like when I go out and therefore I lose my WiFi connection this problem would start immediatly or when I play some heavy video games this problem makes me lose connection or even lagging sometime and the last time it happened the phone couldn’t even find any WiFi in the near area for several minutes even after I resterete my phone.

I don’t think it’s a hardware problem since I got a new iPhone and the problem persist

Maybe it’s a sim problem? Or thermal throttling? ( My battery state is 100 tho)

iPhone 15 Pro

Sounds like a location issue or Network issue...(?) Have you compare your results in a different location
