"Catphone Mobile Ltd," has been producing CAT-branded, rugged and roughened smartphones with the logo of the Caterpillar construction machinery company. The company's phones are certified to industry standard IP68 and military standard MIL-SPEC 810G and are uber- indestructible.

Its IP68 dust/water resistant (up to 3m for 60 mins) feature is one of the highlights of this device. This is simply because, it isn't every day you come across a device of this spec you can dunk in water for up to 30 minutes without severe consequences. It can survive prolonged submersion in water at depths of up to 1.2 meters.

The device features a gorgeous and sharp 4.7 inch TFT display screen with 720 x 1280 pixels screen resolution. Text and images appear quite sharp on the bright screen. You can also binge on your favorite shows, browse the web and enjoy screen time on your phone. The touch screen is responsive and the layout is just beautiful.

To save your multimedia files and documents locally, you get up to 16GB internal storage. For more space to save your files and documents, you can insert a dedicated slot for more space.

Under the hood is a 4000mAh Li-Ion non-removable battery that powers it on. Battery performance is decent. At full charge, it can last you throughout the whole day, depending on usage.

The device is available in elegant black color variants. However, if you already own this device and are ready to sell CAT S31 for cash, here's everything you need to know to get a good deal.
