Can you buy an iphone 5s (tmobile) without a contract plan?

I want to buy an iPhone 5s, tmobile, but without a tmobile contract or number, is that possible? Or Do I have to get a mobile plan to come with the iphone?

Added (1). For the full price*

Added (2). I want to get the phone for my sister, in Europe, so I don't need a contract.

You COULD, but then the phone would be $549 (the retail price)

You can outright buy the phone by itself. Then get wireless contract-free service from Solavei. Solavei gives you unlimited talk, text, and web for cheap and uses T-mobile towers. Check it out.www.solavei.com/HappyMackey

Yes, you can buy it without a contract. But you will have to pay full price.

iPhone 5S with no contract:
16GB - $649
32GB - $749
64GB - $849
