Query: I would give negative stars if I could.

Do NOT do business with these people. They charge you out the nose for their service, then they have all these rules and such to basically charge you for things you are not using, then refuse to pay you back. These jerks are taking advantage of kids, teenagers, and young people who can't afford a regular cell phone. I am on a mission to tell people how bad this is. Keep it in mind before you buy any of their products.
