Will the Lumia 52X work on Boost Mobile?

[carloswin07]

I want to buy my mother a Lumia 52X, but her carrier is Boost Mobile. Do I have to unlock the phone I decide to buy? Which one will it work (520,521)?
Again, this is for the United States' Boost Mobile that I believe is based on Sprint.
Thank you!

There is no CDMA variatnt of the 52x's so I'm afraid not, although I could be wrong.

but all signs point to no unfortunately
