If you have an iPhone, do you get internet connection without connection?

I see people at school and stuff with iphones and they are on facebook, and google, and etc… How do you do that? Does it automatically come with the phone, or is it extra to get connection when you don't have any…

Yea it's called 3G( internet provided thougj phone company) there should be a symbol on the top banner of your iPhone that's says "3G"

Also some of there people may know the school Wi-Fi channel too.

Yeah 3g

Since you are saying no connection, that means they have Wi-Fi there… The phone will use Wi-Fi so even if no internet connection you can't make calls but can use internet.
