Buying iPhone from a carrier?

Is it possible to walk into a store like Verizon or At&t and buy an unlocked iPhone without a plan? Are there any restrictions like age or credit? Can I simply buy an iPhone with cash?

Resetting my iPhone?

I was wondering, if I were to completely reset my iPhone so it was like I had a new phone, would I be able to sign back into my Apple account if I wanted to? My phone is backed up.

I'm looking for an alternative to my expensive Verizon cell phone plan. For my wife and I's phones i pay $170 per month?

I live in North Central Florida and would like to have decent coverage but more affordable.

I just purchased new premium phones for both of us so we can't just switch now unless there was some sort of offer to buy the phones from verizon etc.

We only use 5 GB of date per month because we mostly use home Wi-Fi.

We would prefer to keep our current phones S8 & Iphone8.

Any current promos applicable to our situation would be great!

I'm a veteran if the carrier offers veteran discount that would be great as well.

How can I convince my parents to let me have a phone?

I'm twelve and I've been trying to convince my parents to let me have a phone for the many reasons it's very important.

So I started photography, and as you may know you can't easily carry a camera around your neck all day, waiting for the perfect shot. Having a camera on a phones could be a way I could capture perfect moments without having to switch a ton of gears and wait for it to focus, which can be never on my camera.
I also have no form of social life outside of school, and the only time I can communicate with my friends is in the halls, for about 30 seconds a pop. I want to be able to actually have a couple good friends by the time I go into high school. And it's another way for me to communicate with my parents anytime, or any other family member I don't see that often, or at all.
I've started doing things like band and some math club my teacher pressured me into joining, so if something is cancelled I don't have any way of telling my mom or dad they don't have to pick me up unless I borrow a teacher's phone, which is kind of awkward. And if I ever need to know anything, a phone is there. Our school has chromebooks, but they're big and bulky and half of the websites I need to go on are restricted.

I'm not asking for an iPhone X, but having some form of smartphone would be great for a whole lot of reasons. But my parents won't give in, no matter what. Any advice on how I can have them change there mind?

IPhone 7 Plus Wi-Fi connection problems?

Its running on IOS 11.2.2, it was originally my phone but its paid off and I gave it to my brother because he broke his phone. The whole time I had it, I had no problem connecting to my home Wi-Fi or any other Wi-Fi. At the AT&T store, we set the phone up as a new phone. So everything was reset. Well now my brother is having trouble connecting it to his Wi-Fi. His wife has no problem connecting her devices. His router works fine. He reset the phone and reset the network settings but its still doing the same 'wrong password' problem. What else can he do?
