Updates for factory unlocked s4 active ??

[maverick4227]

I recently bought a factory unlocked at&t s4 active. Will i still get updates from samsung even though its unlocked from at&t carrier. Mine is struck at 4.2.2 . When I try to update it in About device>Software update it says "Software update interrupted. No updates available. Plz try after 24 hours".
Will be happy if someone has answers for this.
