Is sprint and boost mobile the same thing?

So I'm shopping online for an iphone 5c and in the description it says for (sprint users) and I have boost mobile. If I buy it can I still activate it even though I have boost? I have heard people say that they are the same but I don't want to buy it and be disappointed by the outcome.

Boost Mobile is owned by Sprint, and Boost uses Sprint's network, but they are technically different carriers. I know Boost is usually able to activate Sprint phones, but I'm not certain what the limitations are (if any). I would recommend getting the ESN for the phone you're planning to purchase, and calling Boost to see if they would be able to activate it. They should be able to tell you yes or no pretty quickly.
