Opening A 2 year contract with T-mobile?

Soon I'm going to get an iPhone 5s with T-mobile when the iPhone 6 comes out (so they'll be cheaper). I'm only 18 and this is my first time ever having something open in my name. I know whenever you open a new contract they take your social security number to do a background check but the problem is I don't know how much I'll have to put down with a clean credit report. Maybe someone can give me an estimate? I prefer someone who did/does work at T-mobile. I'm trying to save up to get my phone because I know they'll go out of stock FAST when the 6 comes out but i don't know how much to save.

T-mobile doesn't do 2 year contracts any more…

Do call t-mobile then speak to them, explain your age and your concerns, just ask their customer service reps to help you understand what you need and the prices. Cheers.

T-Mobile don't have 2 year contract any more. However you have to be concern with one issue. You have the option of paying for the full cost of the iphone 6 or make monthly installment to pay off for the phone within 24 months.

If you wish to make monthly payments for the cost of the new iphone, then you better have good credit. T-Mobile does require a good credit in order for you to make monthly payments and they will check your credit score if you wish to pay monthly for the cost of the new iphone. Otherwise you would have to pay full retail value with no discounts for the phone, which will be expensive.
