Sign [Q] slc22 dual sim

I just bought a note 3 slc 22 from kiddie au in Japan. According to the specs, this phone is gsm and cdma compatible. Does this mean I do not have to unlock it? Am I correct in saying my phone should work in the states?

I am confused as to which network the lte 5 for AU kiddie is on, gsm or cdma? I looked it up and could not find an answer. I have both an Imei and meid number, is this normal? If I am running on a cdma network, and I try and unlock it for gsm, will this compromise my current carrier?
