Due to the demand from Chinese customers, Samsung usually releases dual-SIM variants of almost all its smartphones in China. Today, Samsung has quietly introduced a dual-SIM caring of its flagship smartphone, the Galaxy Note 4. The Galaxy Note 4 Duos comes in three variants; the first one (SM-N9109W) works with China Telecom, the second one (SM-N9106W) for China Unicom, and the third variant (SM-N9108V) is a SIM-free device. The first SIM card slot on all of these variants supports 4G over TDD-LTE and FDD-LTE networks, while the second SIM card slot can connect to 2G networks. The SIM-free variant of the Galaxy Note 4 Duos is compatible with 4G LTE networks on most carriers, and is priced at CNY 5,400 ($880/€700). The pricing information about the other variants of the Galaxy Note 4 Duos isn’t available yet.
