iPhone 13 cellular data inconsistent

My iPhone 13 has been having a strange issue where my service will go out entirely. It happened for the first time a month ago and then at the beginning of this month figured itself out but was slow, and eventually got back up to speed.


Today it hasn't turned on at all and I have no idea what's going on. I've restarted it and my family has unlimited data, so I know those aren't the issues.


When I did a diagnostic last month, Apple Support said that it may be a hardware issue, but I don't know how accurate this is because it did work for quite a while with no issues.

To be able to use any SIM across the globe you must have "No SIM Restriction" against Network Provider Lock. Please refer to the pic below.




If you see No Service or Searching in the status bar on your iPhone or iPad (Wi-Fi + Cellular), your device isn't connected to a cellular network. If you see SOS or "SOS only" in the status bar, your device can still make emergency calls.
