I need help with an iPhone Field Test

With these screenshots you basically disclosed your approximate location, so if you want to avoid being traced, I’d probably start no to upload sensitive info to public websites

Those screens are just about your cellular connection. I'd recommend checking Settings>General>VPN & Device Management. Most users aren't going to have anything here. If you subscribe to a VPN service such as Nord, McAfee, etc it would be listed here. If your device is managed by your employer it also may be listed here. If there is something you don't recognize at all this could be the culprit.

You'll also want to check Settings>Privacy & Security>Location Services>Share My Location to see who you are sharing your location with via iOS's native location sharing. You can also review the list of apps to see if there are any you don't recognize and either delete them or turn off location sharing with them.

If you find anything suspicious you may want to check with law enforcement before deleting it as you may want to preserve as evidence or justification for a restraining order.

To be a bit less toxic, should you ever have the feeling that you are being traced, you can activate Lockdown Mode and which will decrease your iPhones attack surface significantly, making it almost impossible to access for threat actors. (Lockdown mode is designed against the most sophisticated attacks, and most people will never need to use it.)

A "Field Test Mode" on an iPhone is a hidden menu that provides detailed technical information about the device's cellular signal strength, connection quality, and other related data. This mode is typically used by mobile network technicians, engineers, and advanced users to gather information about network performance and troubleshoot issues related to cellular connectivity.

Please check the internet speed and the bandwidth that you are getting. Disable WiFi before running this Field Test.

You may check the current LTE band/5G/4G/3G by dialing *3001#12345#* and pressing the call button and then selecting the Serving cell info option

See the pic below which is self-explanatory

This has nothong to do with access to your data on your device.

If you feel an unauthorized person/app is remotely using, controlling or monitoring your device, then that is possible only if you have done one or more of the following Don'ts...

1. Don't hand over an iPhone to kids or to a stranger without Enabling Guided Access
2. Don't share Apple IDs
3. Don't Jailbreak
4. Don't share sensitive information pertaining to your device
5. Don't give in to Phishing
6. Don't plug in your device in Airports and Public places through third-party cables and trust the device. Beware of Juice Jacking. (Especially in India)
7. Don't leave your iPhone unlocked and unattended in public places like offices, schools, malls, etc.

If one of the above is true then quickly change the Apple ID Password and Return iPhone settings to their defaults.

Your question makes absolutely no sense.
