I want to buy an iphone 5s

I want to buy an iphone 5s with a 2yr contract that's the cheapest way. But I don't have any credit at all. So would I have to pay the full amount which is $700 and I only have $750 how much would I have to pay at sprint? At least to get a 2ur contract with no credit?

If you're just starting service with Sprint, and want to avoid a contract, you may want to go to a Sprint store and look into the Framily Plan. You finance the phone over 2 years. A down-payment may be necessary. The monthly service starts at $55 for unlimited talk and text, and 1GB of data, and you can "buy up" to 3GB of data for $10 more, or unlimited data for $20 more. Remember that while there's no service agreement, you may be required to pay off the phone if you terminate your service.
