How to hook my iphone up to a number?

I use my iphone as an ipod so when i take the bus to school it diesnt get internet, which is fine. But i was wondering if it was possible to hook my iphone up to a phone number. So that wat, i can use the iphone as an actual phone to call outside of home but still not have 4g or 3g turned on like i don't get internet ourside of home, like it doesn't charge for it at all

Call a service provider (verizon, att, tmobile, etc) and see what plans they have.

  • Why is my iPhone number being displayed wrongly on my number? My number is X, but on "my number" settings, it's being displayed number Y. Why is that? Also, some people told me that when I call or text them, the number Y is appearing to them, not the number X as it should. On the other hand, if I call the number X, my iPhone rings normally, but the same thing doesn't happen when I call number Y.
  • My number is invalid number in viber, I have an Iphone 5s? When I want to setup my Viber on my Iphone 5s it shows an error that says "invalid number", every number that I put is an invalid number. What should I do?
  • My iPhone won't charge no matter what i hook it up to So when i plug it into my home to charge, it does for a second then either just stops or has a plug sign inside the battery. When i plug it into the computer it says that the USB was drawing to much power and was disabled. It said that on both of the computers i plugged it into and with both of the USB's i tried. It is now dead. It just started doing this today and worked perfectly fine yesterday. How to fix this?
  • If I buy an unlocked iPhone 5, can I hook it up to other services? I really want an iPhone 5, but the prices are way too much! 80 bucks for unlimited texting and data, but only 300 minutes of calling? Uh, no. Unlocked iPhones are more expensive up front but can pay off in the long run. If I buy an unlocked one, can I hook it up to Virgin Mobile or Cricket?
