How to get 24/7 internet connection on my iPhone without via carrier?

I need a internet connection on where-ever I go.

I've heard about MiFi, Mixfi, or Freedompop, but I'm a girl, so I don't know this stuff, please help!

In order to use MIFI and other hot spot devices you have to have data plan. When at home you would not have your hot spot on and you would use Wi-Fi. It is important to know that data can be used up pretty quickly. You would need to have an unlimited data plan.
