The FCC documentation shows that the device was carrying AT&T's frequencies for GSM, HSPA and LTE connectivity. The carrier has been stocking its shelves with some Nokia Lumia models, including the Nokia Lumia 925 which launched today at AT&T for $99.99 with a signed two year pact. But we digress. This is a Samsung produced model and we will have to wait to see what goodies the Korean OEM is bringing to the party with this unit.
