Thanks for interest.

Can someone explain why this cannot be used on boost? I'm not very tech savvy!

you can switch into Sprint carrier.

Im not sure what that means

It’s SPRINT ONLY.

It means it is not paid off since Swappa does not allow blacklisted phones.
If not, the seller can unlock the phone through sprint if the seller has account active with them.

Tim that's not correct. Just means it hasn't been used 50 days on Sprint. That's the amount of days it takes to be active on Sprint before they will unlock. Regardless even if paid off.

Will you do local pickup? Want this asap

yes local pickup available.

There is no such thing as a not paid off phone on swappa. As a former seller, you have to put in the serial number before you are allowed to sell and they scan it to make sure paid off. Former Boost customer here and as such you should know that Boost generally has a list of factory unlocked phones that it accepts but we are talking UNLOCKED from the factory right at start. Not a Sprint phone that you yourself unlocked--those will not work on Boost--unless boost has that particular phone on a list of phones from Sprint that it is willing to accept unlocked. They keep a detailed list, and I checked the list and this one is not on it. This means unlocked or not, it will NOT work on Boost. Lastly, unlocking any major phone can be done for 19 dollars online. CellUnlockerPro search that name. There are many others. For 19 dollars they will unlock anything but your house door. But unlock means GSM in the case of Sprint. It will move to ATT or TMobile and perhaps some of there subcompanies.
