Right off the bat, this phone looks like it was made for Batman. It has been called the Hulk of mobile phones, but I prefer to think of it as the BatCell.
The physical form of the phone is its main weapon, it is made from a combination of rubber and fiber-glass, at the front we have 2.2 inch Gorilla Glass (1.5mm thick) QVGA 240x320 display capable of supporting 65,000 colors. It can withstand a nail being hammered into it three times in a row. Although a seven foot drop will break the screen. The phone weighs a truly hefty 185 g and has dimensions of 126 x 60 x 25 mm.
The control center is made up of the four-way D-pad which is flanked by three buttons on either side, to the left; Select, Clear and Call. To the right; Contacts, Back and End Call/Power. The dial pad is evenly spaced, comfortable to press and backlit, all the buttons are easy to press as long as you are not wearing gloves, which sort of defeats the purpose of a rugged dial pad, as the users of such tough phones are generally expected to be heavily gloved (construction workers, outdoor enthusiasts, Batman etc).
On the right side we have two flaps (mud and water proof) that house the 3.5 mm headphone jack USB charger, further down is the web activation button and JAVA programing key. The right side houses the very thick and flat volume rocker, further down the spine we have the camera shutter key, which also acts as the LED flashlight's power button.
Turning the phone over we find the the 2MP camera lens and LED flashlight, the flashlight can be used for cinematography purposes or simply to illuminate your way inside the Bat Cave.
The Sonim comes with a special screwdriver used for opening the back, unscrew the two very tight screws and you are provided access to the battery and microSD card slot.
