Let’s say I have a phone and I send messages to friends, one through encrypted messaging, and one through un-(non?)encrypted messaging (do these even exist anymore?)
What makes the former more secure? How does one access the latter?
If someone has your phone password they are of equal security of course, but if they don’t then what protections does the encrypted service offer that the unencrypted one doesn’t?

There are (free and legal) tools to read what data goes to what service from which device if you are on the same network. If you use encrypted services, the data you send will be scrambled with an algorithm that needs a key to unscramble. If someone wants to see it without permission, they won’t have the key to reveal what’s in it. If it’s not encrypted, anyone can read it. On a public WiFi with potentially hundreds of devices on it, you can never know if someone is looking for unencrypted messages. Not to mention service providers, authorities or malicious software that could be between your device and the server you’re sending data to
