Samsung has announced the launch of its dual-SIM Galaxy S Duos, which will hit the European market by September this year. While not likely to be a market leader in terms of sales volume like the Galaxy S III, the Galaxy S Duos could nonetheless be a hit in emerging markets, where dual-SIM setups are popular.

Samsung is known for a wide range of devices, which cater to almost all market segments. The lower-end Galaxy line is mostly meant for emerging markets that prefer cheaper mobile phones. But while dual-SIM offerings have previously been limited to cheaper devices, the Galaxy S Duos intends to straddle both mid-range and low-end markets with its feature offering.

The device derives inspiration from the Galaxy S III in terms of design. Specs-wise, though it’s significantly less powerful than its flagship brethren.

The Samsung Galaxy S Duos specs include a 1 GHz single-core Qualcomm Snapdragon MSM7227A processor with a 1500 mAh battery. The phone will have 4 GB of internal storage, expandable through microSD. Multimedia-wise, the phone comes with a 4-inch WVGA display, 5-megapixel rear camera and VGA front-facing camera.

The Galaxy S Duos won’t win any benchmark challenges against its flagship counterparts like the S III. But the point here is that the phone will support two SIM cards at a time, letting the user call, text and use data from two separate accounts or networks.

Samsung says this is intended for users who want the flexibility to balance work and personal calls. But we figure that at present, multi-SIM capability is usually targeted at emerging markets where different prepaid SIMs are used to handle different types of calls (depending on the carrier promo or deal).

No price has been announced, but Samsung has confirmed a September launch, initially targeting the European market. An LTE variant is also planned.
