Samsung S7 Edge from sprint to Boost Mobile Network.

[wireless shack]

[Bi want to buy a samsung s7 from sprint online like ebay or amazon, and connect it with boost mobile,..my question is what do i have to do to get it to connect to boost mobile network, do i just insert a boost mobile chip or get the phone unlocked, or something?
i already have a boost mobile account, i just wanted to make sure before i buy it. ..

You have to check with Sprint to find out whether they'll allow a phone with that ESN on their network. (That means getting the ESN from the seller before buying it.)
