Built to survive, the CAT range of rugged mobile phones is the ideal choice for those who pursue an outdoor lifestyle, and those who need a tough smart phone that can stand up to the rigeurs of their work. The CAT S31 is no exception, forged in the heritage and pedigree of the brand, the CAT S31 Dual SIM mobile is built to withstand the elements. Featuring industry leading MIL-SPEC 810G Certification, and built to IP68 certified rating, this tough phone is as tough as it looks. It's waterproof for 35 minutes in up to 1.2m of water, and can withstand thermal shocks and fine particulates such as dust. The S31 is as tough as they come.

You'll also be safe in the knowledge that the CAT S31 mobile phone is drop proof tested to ensure the toughness extends to the screen - this rugged smartphone has been proven to withstand drops onto concrete from up to 1.8m. The CAT S31's 4.7" HD Resolution touch screen is also protected by scratch-resistant Corning Gorilla Glass 3 to ensure clarity and protection is as good as it can be.

From it's Quad Core processor through to it's 2GB RAM, this super tough phone is ready for whatever apps you can throw at it. You'll also receive your phone running Google Android 7.0 so the latest apps will run with no problems.

The dual SIM CAT phone packs in perhaps the most desirable feature for those living an active lifestyle where you'll be away from power sources for extended periods of time - a longer battery life. The S31 features a large 4,000 mAh battery which can provide you with 15 hours of talk time over a 3G connection, or up to 38 hours standby time. The S31 ensures you can enjoy the outdoors without needing to be tethered to a charging point. You can also use the phone with gloves on thanks to it's glove mode - say goodbye to cold hands when using the phone!
