Samsung announced the Galaxy S Duos on Monday, the newest addition to the company’s Galaxy smartphone lineup.

Sporting a design similar to Samsung’s popular Galaxy S III smartphone, the Galaxy S Duos comes with one feature not found on many smartphones: the ability to support two SIM cards.

Dual-SIM support would allow you to have two different phones numbers, running on two different networks, on the same phone. For instance, if your work number is on AT&T and you use T-Mobile in your personal life, you could pop both SIM cards in the Galaxy S Duos and use the same phone for both accounts.

“Its unique ‘Dual SIM Always On’ feature allows you to receive calls on one SIM number while taking a call from the other, ensuring that you can manage both personal and work commitments without ever missing a call.” Samsung said in a blog post announcing the phone. “You also have the flexibility of selecting different billing plans for either SIM, switching between them at your convenience.”

The Galaxy S Duos has a 4-inch 480x 800 TFT touchscreen display and ships with Android 4.0 Ice Cream Sandwich. Under the hood, the phone has a 1GHz processor and has 4GB of built-in storage. It also has a 5-megapixel rear-facing camera.

While on the surface the handset looks similar to the Galaxy S III, it's significantly different in some key ways. Specifically, the Galaxy S III has a 4.8-inch Super AMOLED screen with 1,280 x 720 resolution.

The Galaxy S III also has a higher-resolution 8-megapixel rear-facing camera and comes with 16 or 32GB of built-in storage. A number of other features are a cut above the S Duos on the spec sheet as well.

The Samsung Galaxy S Duos will be available next month in Europe, with no word on when or if it will ever head stateside.
