You have the international version of the Note 3, which comes factory unlocked out of the box if I'm not mistaken.

as far as the SPC I don't know why you'd need it, in this case the MSL or SPC is 8 digits for Samsung GSM models, DFS, cdma workshop and other cdma tools will not be able to help you with that, are you trying to region unlock it? 4.4.2 is region locked now with samsungs, try using chainfires downloadable app to region unlock it, it might work, might not.

Worth a try, goodluck!
