I've had virgin mobile for the past two years. Now I want to switch to Sprint to purchase the iPhone 5. Being only 21 years old I dont know how my credit score would affect with trying to open a sprint account. I am living in a dorm and I only pay my internet/cable bill that has my social security number on it. I make those payments on time. And have nothing in collections. Would I be able to open a sprint account without a hefty deposit? Thank you for your time and answers:-)
