Cat B40 – a dumbphone with maximum attitude (smartphone review)

The Cat B40 is a dumbphone, well, an IP68, IP69, drop-resistant feature phone with large alphanumeric buttons suitable for traditional gloves and perfect for rugged use.

Cat caught our eye while researching waterproof phones – fact or fiction (smartphone guide), and it’s the only brand that goes further with IP69 (protected against high-pressure, high-temperature splashes for a short period of time). scope).

I call it a dumbphone because it’s not an Android or iOS phone. It’s like the good old Nokia phones of yesteryear that can:

  • Store contacts (on phone)
  • Send and receive SMS
  • Make phone calls and keep logs
  • Has a suitable camera and gallery
  • Cat applications (torch, world clock, stopwatch, unit conversion, audio/video media player, sound recorder and organizer)
  • FM radio (requires 3.5mm headphones plugged in)
  • Clock and Alarm Clock
  • Calendar
  • Calculator
  • Games (Doodle Jump, Crossy Road, Stick Hero, Bubble Party Mix, Super Pet Twist, Football Cup)

Unfortunately, no Nokia Snake!

CyberShack’s take – If you need a rugged phone, the Cat B40 is it

This phone is used worldwide by rescuers because it works in 2/3/4G and is ultra-reliable. It doesn’t matter what’s under the hood as long as it does its job.

Cat also offers Android smartphones, including the Cat S62 Pro with a Thermal Flir camera.

We won’t rate the B40 per se as it’s unique and none of our test software works on the dumbphone. Suffice it to say, if you need it, you know what to buy.

Why buy it?

It’s not complex like a smartphone – probably in your muscle memory if you used a feature phone before 2007.

It’s rugged, bleach-, chemical-, and germ-resistant, and has a 100-lumen torch and buttons. The Cat B40 is just about calling and texting under pressure and getting the job done every time.

And you won’t (can’t) catch any virus/malware because there are no patches or updates.

Why not buy it?

If you need access to an internet browser, the 2.4-inch QVGA color display isn’t for that.
