Durable design.

The CAT S42 prides itself on being super reliable and durable. If you’re in a job that means you’re often covered in dust or dirt or working at great heights, this phone is for you. It boasts an IP68 and Mil Spec 810H rating making it drop-proof, dustproof and shockproof. It’s also extra hygienic and can be submerged in hot soapy water and scrubbed – meaning dirt is no problem. It also delivers loud, high-quality audio which is perfect for those noisy days at work.

A display that doesn’t disappoint.

The CAT S42 boasts a 5.65-inch HD display that packs impressive brightness. Whether you’re outside in the sunshine or somewhere dark, you’ll be able to see and read your screen clearly. The display packs Corning Gorilla Glass 5 which makes it resistant to any scratches and every-day wear and tear. The best bit? You can use your phone while wearing gloves, making it easier to use during the job.

Long-lasting battery.

If you find yourself working super-long hours and need a phone that can keep up, the CAT S42 is perfect. It boasts a 4200mAh battery which delivers up to two whole days of use – meaning you can worry less about running out of charge!

Incredible performance.

The CAT S42 is great at keeping up with you when you’re on the go. Curtesy of the Mediatek Helio A20 Quadcore processor, you’ll get to enjoy top-class mobile performance. Google Android 10 also means extra perks for you! The positives just keep on coming with this phone.
