Entry Level for CAT phones
The CAT S31 is a solid smartphone whose main task is not to break. It achieves this in any case, but users have to do without demanding applications.
Smaller and cheaper than the S41, this is a similarly robust-looking handset, but one which trades a degree of toughness for a more pocket-friendly design.
The CAT S31 is at the cheaper and simpler end of the scale, lacking in the performance of the more expensive S41, but almost matching it in terms of toughness.
If you need a tough phone for work - or are looking to buy them for your employees - but don't require much in the way of performance, the S31 is worth looking at. It can handle email, web browsing, photography and useful apps aimed at use in the construction site. It lets you bring smartphone functionality to hostile environments, but is unlikely to be your one-and-only handset.
Pros:
- Water resistance and military-grade toughness
- More compact than large CAT S41
- Large battery
Cons:
- Middling performance
- Display has Gorilla Glass 3, not 5
- Not as secure to hold as the squarer S41
