Usually when I leave the house I turn off wifi and just use mobile data
I would stronly recommend that you set your wifi to only join trusted networks. That way you can also just leave the wifi on and not have it connect to every random network it encounters.
I would still recommend turning wifi off when leaving home. The process to identify if a network is trusted or not requires a handshake. So leaving wifi on makes you trackable by the wifi network operators and the apps on your phone with access to your wifi.
Your provider will just see encrypted traffic (mostly), so yes it will provide protection.
Only if you trust your VPN service more than your mobile Internet provider.
You forget that nation-states control your ISP. And of course you can choose your VPN provider or run your own.
Protection from what?
If it’s your phone leaking your location, then yes and also disable location services and Bluetooth as well.
You mention interference. Mobile data can be interfered from miles away at the phone company. Same for your home internet.
Only if you live in a country like russia, china, iran, north korea or south arabia
Any public data exchange has an element of risk, but the management/priority of that risk relates to tour relevant risk matrix/profile.
Any exposed data transverses via a provider, be it mobile or Wi-Fi. If you are concerned about provider vulnerabilities and exposure, be it Wi-Fi or mobile, use a VPN and related encryption.
What sort of protection are you after? Your VPN should encrypt your data to make it more difficult to snoop on your activity. I wouldn’t trust any random WiFi hot-spot just because you got a VPN encrypting your traffic though.
Definitely not a stupid question! Networking infrastructure is complex. I've been working in IT for years and still find myself scratching my head at times going, "Wait, how does the OSI model work again?"
Connecting to a VPN on your phone while using mobile data basically means the cell phone tower handling your data only sees encrypted data. Whoever your VPN provider is will see your traffic instead of the cell tower.
However, in modern times it's fair to be wary of backdoors and exploits that can compromise your device and render the VPN encryption moot. There's not much that regular people can really do to mitigate that possibility other than not use a phone.
If you're interested in learning more networking fundamentals, I'd recommend starting with the OSI model and its layers.
A handy mnemonic I whipped up with ChatGPT last year for better remembering the order of the layers:
Precise Data Navigation Takes Some Planning Ahead
The spyware in your radio firmwarr always has direct internet access and it won’t use your vpn
Sent from their Android
Btw you can have battery powered wifi to lte bridge hotspot. This neuters to radio in your phone.
As far as the spyware inside the radio, android or apple, doesn’t make a difference, they don’t make radio firmware.

You’re hiding your traffic route from your mobile operator and giving it instead to your vpn company who swear they are honest

I run my own wireguard VPN at home and connect to it from my phone when I'm traveling.
Grant's me privacy (but not anonymity) from my mobile carrier. Sure, my home ISP still sees my VPN's traffic, but that's still one less company able to monitor my web traffic when I'm mobile.

Running your own VPN in that situation is a good use-case agreed - assuming you trust yourself :)

Same. Also feels a bit safer connecting to public wifi.

Well facebook VPN waa sniffing data to see what other aocial media the person was using. But something like Proton that prides itself on privacy and encryption should be fine

Absolutely. Unless they’re actually evil. Which I’m sure they aren’t. But they could be.
