Check out GalaxSim Unlock on Google Play to see if this app is available for Sprint Note 2.
It works well on N7100 International version.

This will sound stupid but do yourself a favor and sell it on ebay while used ones are still fetching good money and then buy an international korean model, no sim lock plus 6gb ram. I almost bought the tmobile one til i found out about the korean version.

First I try to repeat what I understood so far: You have a Note 10+ US version with locked bootloader which should be network unlocked from Sprint.
So you should be able to use a SIM card of a different service provider.
Does the device recognize the SIM card?
What exactly does not work?
Maybe it is just an incompatibility with special bands (LTE/4G, 5G).
