Cat S75

11 min read


A telephone with a specialised use in thoughts, the Cat S75 is hard sufficient to take some severe hits, and will be plunged into water safely. However if you take away its toughness and satellite tv for pc messaging characteristic, it’s simply one other mid-ranger.


  • Satellite tv for pc messaging
  • Good battery life
  • Large and hard


  • Large and heavy
  • Display screen is merely OK
  • Restricted satellite tv for pc protection proper now

  • IP68 ingress safety: Presents protections in opposition to sand, mud and dust

  • Satellite tv for pc messaging:Satellite tv for pc capabilities unlock improved messaging connectivity.


You may already be acquainted with the Cat model for those who’re within the behavior of shopping for work boots, or presumably earth-moving gear.

The Cat S75 isn’t fairly on the identical scale of toughness as a digger, nevertheless it’s a chunky telephone which ought to be capable of survive tough remedy, and may get a message out even for those who’re in the midst of nowhere (in Europe, a minimum of) because of its satellite tv for pc connectivity and lengthy battery life.

Nonetheless, take away these options and it’s a reasonably unimpressive mid-range telephone that targets a selected area of interest, and received’t be engaging to anybody outdoors it.

Design and display screen

  • IP68 ingress safety
  • Massive, cumbersome design
  • Coated with hardy Gorilla Glass

The Cat S75 is barely thicker and heavier than most telephones. There’s additionally a thick bezel across the display screen, however aside from that there’s nothing that marks the S75 out from different Android smartphones.

There aren’t any noticeable sealed doorways over the USB port, as you’d discover on a rugged laptop computer – it seems like a standard, if considerably chunky, telephone – however there are two additional buttons. The one on the left is massive, supreme for urgent whereas sporting gloves, and is programmable.

The one on the highest, which is smaller and colored crimson, is designated as an emergency alert button – maintain it for 5 seconds and an SOS is shipped through (by default) the satellite tv for pc message service. The facility button on the right-hand aspect of the handset is above the amount rocker, like on a Pixel telephone, so could take a little bit of getting used to in case your present handset has them the opposite method round.

A telephone like this isn’t meant to be flashy, it’s meant to be powerful, and meaning an armoured plastic again that wraps across the sides, as if it was already in a protecting case. It’s massive, however actually not uncomfortable to carry – although there’s a ridge across the display screen that you simply’ll actually really feel together with your ear. The built-in safety makes it much less slippery than some glass telephones, so it’s much less prone to slide off the couch, or the deck of a ship.

The display screen is coated with Gorilla Glass, and the handset ought to face up to a 6ft drop onto a metal floor in addition to submersion in water as much as 5M deep for 35 minutes. This isn’t the promoting level it as soon as was – many telephones now sport IP68 ingress safety, and placing your present telephone in a protecting case is likely to be all the additional toughening it wants.

The display screen, an IPS panel with an FHD+ decision, does a reasonably good job however pales compared to among the AMOLED fashions on the market. Once more, this can be a telephone you’ll wish to purchase due to its satellite tv for pc messaging and skill to shrug off tough remedy fairly than one thing to stream Netflix on, however having a pleasant display screen actually helps.

It has a barely tough texture to it, distinct from the texture of a much less rugged telephone’s display screen, which makes me marvel if there’s an built-in display screen protector in place too. It’s fairly reflective in direct daylight, and never the brightest I’ve seen, however you need to use it whereas sporting gloves or with moist palms.

Other than the digicam bulge, fingerprint reader (smaller than these on different telephones, maybe to assist maintain mud out), additional buttons and Cat emblem there’s nothing that stands out visually in regards to the telephone. Maybe its very genericness is one other layer of safety. 


  • Essential sensor has 50MP sensor
  • 8MP Ultrawide and 2MP Macro
  • Poor photographs in low-light circumstances

On the again of the Cat S75 there’s a modest digicam bulge, that includes three lenses and an LED flash (which, in a pleasant contact tailor-made to its meant use, is basically vibrant so you need to use it as a torch whereas escaping from caves).

The primary digicam is a 50MP unit, with a most aperture of f/1.8, which makes use of the Isocell JN1 sensor from Samsung. Introduced in 2021 and used on telephones by Redmi and Nothing, it places out completely good 12.5MP recordsdata, although they’ll lack the color pop and element of pictures created with newer sensors.

Switching between focal lengths isn’t achieved with a faucet in the best way most Android telephones do, however utilizing a slider. This implies it’s simple to vary to the 8MP ultrawide digicam – and certainly it should do that routinely in some circumstances – fairly than persist with the higher high quality recordsdata produced by the principle digicam.

It’s a clumsy method of doing issues, and can result in some disappointing outcomes, as the pictures from the ultrawide are noticeably worse than the principle digicam’s pictures.

There’s a 2MP macro digicam too, however the low-resolution recordsdata it produces aren’t significantly better than zooming in on a nonetheless from the principle digicam taken at its closest focusing distance, and it may be arduous to focus with.

In low gentle the picture high quality falls aside, although it’s helped by that vibrant flash. The standard Android night time mode requires you and your topic  to remain nonetheless, so doesn’t assist drastically, and also you’ll see elevated noise and an absence of definition in shadow areas. Video choices are slim, with a alternative between 720p or 1080p recording, plus time lapse or gradual movement. 

Naturally, the digicam can be utilized underwater. Triple-pressing the ability button opens the digicam app in underwater mode, from the place you need to use the amount buttons to set off the shutter. I attempted it in a lit aquarium, however the lack of robust gentle elevated the shutter speeds a lot that getting a pointy picture of fast-moving fish was not possible, although chances are you’ll do higher if photographing rocks.

The 8MP entrance digicam is about into the highest of the display screen and, even with HDR mode switched on, produces washed-out colors and smeared element. It’s tremendous for making video calls, however I wouldn’t depend on it for a very good high quality shot.


  • Slower than different mid-range telephones
  • Not the the best choice for gaming
  • Satellite tv for pc messaging solely viable in Europe

The eight-core chipset on the coronary heart of the Cat S75 is break up into clusters of two A78 cores and 6 A55s, an uncommon association from an {industry} that likes to maintain issues in teams of 4.

It has a non-standard GPU as effectively – Dimensity 900 telephones such because the Oppo Reno 7 or OnePlus Nord CE2 5G normally push pixels with a Mali G68 chip, however the Cat has one from PowerVR as a substitute. Which means that the telephone lacks the pure processing energy that others with extra A78 cores – such because the Samsung Galaxy S21 – have, nevertheless it’s actually not a poor performer. 

It won’t be top-of-the-line telephones for gaming, however there’s sufficient there to run the OS, and efficiency in issues like mapping and messaging apps are in all probability extra essential for the audience of a telephone like this.

The characteristic that’s going to draw quite a lot of adventurous folks to the telephone is the satellite tv for pc messaging service, which lets you make contact with civilisation even when out of vary of telephone service, so long as you will get an unobstructed view of the sky.

On the S75 it’s offered by Bullitt, and presents two-way communication for textual content messages, however requires you to make use of a particular SIM card that goes within the telephone’s second slot. This implies you’re unable to make use of the satellite tv for pc SIM and the telephone’s MicroSD enlargement or dual-(regular)-SIM capability on the identical time, although with 128GB of storage on board you may by no means must carry a MicroSD card wherever close to it.

When you’ve arrange an account with Bullitt, subscribed to a plan and logged into its app, you can begin sending messages, although chances are you’ll must align the telephone to the sky first, relying on protection. I attempted it indoors and couldn’t get a repair – you want a GPS sign and a transparent view of the southern sky (I used to be at 51° north), however nonetheless could not get a sign – it frequently stated ‘connection unavailable’ even with the satellite tv for pc in the precise place.

I then tried it in a infamous telephone lifeless spot outdoors a home in Somerset, and located {that a} clear view of the sky (with no buildings or different obstructions) was important. I managed to get some messages by, together with my GPS coordinates, however the app spent extra time telling me the service was unavailable than it did truly working.

The message then comes by on the recipient’s telephone as a standard SMS in the event that they don’t have the Bullitt app put in. Message plans range from 30 a month for €4.99 (£4.30, $5.50), to 250 in an entire 12 months for €59 (£50.50, $64.50). All plans include emergency SOS service, and there’s a three-month free trial of the most affordable plan with the Cat telephone. You may also use it to ship SOS messages that alert the emergency companies.

The one slight problem is within the satellite tv for pc protection. A verify of the Bullitt web site reveals that for those who’re in Europe you’ll be capable of use the service proper now. The continental USA needs to be on-line in June 2023 adopted by Canada and southern Alaska in July. The entire of Africa, Central and South America, Japan and Australasia (besides Tasmania) are marked as ‘Q3 2023’, and if you wish to go climbing in Russia, India, or China you’re out of luck, as they’re marked ‘unsupported’.

Some international locations, reminiscent of many of the Center East, Mongolia, South Korea and Myanmar are ‘unverified’. A few of this is because of wars, inconvenient political regimes, or authorities regulation of satellite tv for pc communications. Issues could change, however on the time of writing that is very a lot a Europe-only system.

Battery life

  • Packs a 5000mAh cell
  • Able to 17 hours on single cost

Given the dimensions of the telephone, and the battery dimension of 5,000mAh – on the prime finish of the ability cells normally utilized in telephones – I had excessive expectations for the Cat S75’s battery life, and I wasn’t upset.

It managed 17 hours of fixed use in my exams earlier than coming into its battery saver mode, which factors to a life measured in complete days if left on standby. If you realize you’re going to be out of vary, you may swap the telephone to a satellite-only mode, which ought to cease the 5G and Wi-Fi from banging away and losing energy.

Cat hasn’t revealed in its advertising supplies how a lot energy the telephone can draw from the wall, however I hooked it as much as a 60W charger and noticed it totally juiced-up in about two and a half hours.

Closing Ideas

The Cat S75 targets a specialised area of interest. Not everybody goes to require a telephone that’s sealed and hardened to this diploma, and its efficiency isn’t pretty much as good as cheaper telephones from different producers.

The telephone appears aimed toward those that intend to get actually misplaced and away from the crushed observe within the wilds of Europe. As soon as the satellite tv for pc service is widened to incorporate extra of the world, then it could turn out to be extra helpful for travellers, scientists, journalists or anybody else popping into the jungle away from telephone protection.

With out the satellite tv for pc messaging system it’s a mid-range telephone that’s let down by having 6GB of RAM as a substitute of 8, and by a GPU that appears a step down from the standard one present in Dimensity 900 telephones.
