Its first SIM card operates on the 850/900/1800/1900 MHz frequencies, while the second works on 900/1 800 MHz.

Next, the Samsung C6112 is a slider phone with support for quad-band GSM/EDGE connectivity. It has 2.4-inch QVGA screen, 2-megapixel camera, FM radio with RDS, Bluetooth, music player, and a microSD card slot.
