Cat Cat S31 overview

  • 1Description

Smartphones are an essential part of our everyday life, but when your everyday life is on a construction jobsite or hiking over rough terrain, you need one that can survive these environments. The unlocked Cat S31 16GB Smartphone is designed to fit the bill. It's IP68 certified and meets the MIL-SPEC 180G standard. Water-resistant, dustproof, shock-resistant and capable of withstanding extreme temperatures, but without having to sacrifice everyday usability.

Packed inside its rugged exterior is a Qualcomm 1.3 GHz Snapdragon 210 Quad-Core CPU, with 2GB of RAM that supports the Google Android 7.0 Nougat operating system. Store your apps, pictures, and other files on the built-in 16GB of memory, or use an (optional) microSD card to add up to 128GB of additional space.

The super bright 4.7" IPS display is protected by Corning Gorilla Glass 3, and sports 720p HD-quality graphics for your favorite apps and games. Take photos and video with the 8MP autofocus rear camera, that features an LED flash. The front-facing 2MP camera is great for video conferencing or taking selfies.

The S31 is unlocked and can be used on 4G GSM/LTE mobile networks, but can connect to the internet and other devices, such as wireless headsets, using 802.11 b/g/n Wi-Fi and Bluetooth 4.1 technologies. A 4000 mAh battery supports up to 30 hours of talk time, or a standby time of 38 days.

GSM / 4G LTE Wireless Connectivity
This phone is designed to work on select GSM networks and is 4G LTE capable. LTE is an advanced cellular network data protocol capable of data speeds so fast that they compete with wired broadband Internet providers. With an LTE connection, this phone should have no problem streaming HD video, downloading apps, uploading photos, or anything else that requires a high-speed data connection. The phone is also backwards compatible with 3G and 2G data for instances when you can't get LTE. In addition to cellular wireless, this phone also features Bluetooth and Wi-Fi connectivity. Note: Not compatible with all cellular networks. Please make sure your provider uses a frequency or band that this phone supports. You can check which bands this phone works with in the Specifications.
Android 7.0 Nougat
The Android operating system integrates heavily with Google's services. Using the card-based Google Now, Android quickly surfaces information for you whenever you need it, powered by the same Knowledge Engine that runs Google's web search. It's a personalized and customizable OS, allowing you to add your favorite apps or widgets to your homescreen. You can even download new themes using the Google Play Store, which offers access to more than one million apps, games, books, music, movies, and more. Android 7.0 Nougat adds major productivity capabilities to the operating system in the form of a multi-window view, which allows for two apps to be placed onscreen at a time. An improved notification system allows you to interact with texts and emails right from your notification pane - without needing to open the app. Other features include file-based encryption, a Data Saver mode, the ability to scale text and icons to better suit your phone's screen, and more.
IP68 Waterproof & Dustproof
Ingress Protection (IP) is an industry standard rating system that determines how resistant a device is to penetration from varying degree of liquid and dust. The S31 is certified IP68, which is one of the highest ratings currently possible.

The S31 earned an IP68 rating by having the ability to be submerged in up to 1.2m of water, for up to 35 minutes. It also proved to be completely protected from dust, making it an ideal phone to handle very dusty, or sandy environments. Including, salt mist spray, salt fog, or sand.
Accidents happen, but when those accidents combine sensitive technology and the hard, unforgiving embrace of concrete, the results could be catastrophic. Cat has ensured the S31 could withstand such damage. It survived a drop test onto concrete from up to 6' in the air, resulting in no damage to the display, internal hardware, or overall usability.
Wet Finger Tracking
The S31 can not only withstand wet environments, but thanks to Wet Finger Tracking, it has the technology to continue to function in them. Even when wet, the S31's screen still works.

Cat Cat S31 reviews

S31 16GB Smartphone (Unlocked) is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Good phone for the money Phone seems to be made solidly although I haven't dropped it yet. I wanted a phone that I wouldn't have to be extremely careful with.� The phone seems to function fine. The battery life seems good.� One negative is that this phone doesn't have a notification light.� To see if you have a missed call, you have to turn it on. Other than that I'm pleased with it.
