How the hell do I start credit?

No idea how to do it and looks confusing. Wanted to buy an iphone 5s but it required a $500 deposit. What the hell, I had enough to buy the phone and start the activation but what's up with paying half a thousand dollars. I couldn't even get a best buy card cause I lack having any credit.

How do I start it and get it fast? What do I have to do?

Start with a cheaper phone. Then take your money to a credit union or bank and talk about secured credit cards.

You could have tried a pre-paid plan. Rather than use then, you pay then use. It helps monitor your downloads as well.

You start by not trying to get Best Buy cards, contract phones, etc. You have to stop trying to get those things. If you have tried too many times, then you may need to wait up to a year without trying.

Next, after you stop trying to get those things, you deposit money at a bank that offers secured credit cards to depositors without a credit history, such as Capital One, and you get only one secured credit card from that bank, and then you stop trying to get things.

You don't get it fast, and you don't get it at all if you are trying to get it fast. To get it, you have to stop trying to get it fast.
