how Can one jailbreake an iPhone?
iPhone exploits are hard. Not impossible, but hard. Based on available information, they also tend to be targeted at investigative journalists, politicians, political dissidents, senior in business or government, and those with access to sensitive or classified data, or to great wealth. Not used widely.
There are easier ways to be followed.
A compromised Apple ID, or a compromised passcode with physical access, for instance.
Or a cellular GPS tracker.
For your iPhone SE, read this: Personal Safety User Guide - Apple Support
If your SE is 2nd or 3rd gen and can get to iOS 16, run Safety Check.
If you have a iPhone 5S and not an SE from the footer, that 5S is very very old, and far before any tools will work with that. And there are known issues with that and other similarly old configurations. If security is a concern, a newer model capable of iOS 17 is greatly preferable.
More generally, nothing I can offer here will ameliorate your concerns, too.
