UNLOCK Samsung Galaxy Note 4 N910P Sprint 5.1.1

I have this phone, but I do not live in the US and can not use Sprint. I do not know who the owner.
How can I unlock it? I tried to put TWRP (to flash custon rom and get root), but failed. I used Odin3 v3.10.7 and TWRP fo sprint, after loading still samsung recovery. I tried different versions twrp and odin.
Android version: 5.1.1 lollipop
