If dual-SIM is just not enough for you, look at this OTECH F1 with FOUR SIM card slots. More exciting is that all four SIMs are active at the same time, making the F1 a true quad-SIM phone. The phone, at the same time, is a Blackberry-copycat with QWERTY keyboard and a Blackberry-like UI.
The OTECH F1 has a 2.4-inch color display and a so-called 12.1 Megapixel camera on the back. It packs also built-in TV tuner, FM tuner and Bluetooth.
