TC-638 dual SIM card phone

Over in Asia where SIM cards are widely used for mixing and matching services, dual SIM phones are very popular. This TC-638 device is another one to add to the list. Featuring a 2.4 inch touchscreen and 108x49x17.5 mm, the phone has a pretty nice screen-to-relative-size ratio. The TC-638 also packs in microSD support, stereo speakers (3D sound), a 2 MP camera, and of course, dual sim support.
