Description of the Cat B35 Dual Sim Black

This Cat B35 Dual SIM Black is a great simple smartphone. If you're looking for a simple phone that is perfect for making calls and sending texts, this B35 is a great option. This device is incredibly sturdy and can handle a lot of wear and tear, which makes the B35 an excellent phone for building sites and rough terrain.

Even though the phone isn't a smartphone, the device still comes fitted with great features. Aside from making calls and sending texts, you can access the internet via WiFi and 4G. The phone also comes fitted with apps that normally only appear on smartphones!


The Cat B35 Dual SIM runs on the KaiOS operating system, an operating system that was developed specifically for simple phones. Thanks to this operating system, you'll still get access to features and apps that normally appear on smartphones. The only thing this phone doesn't have is a large touch screen!

Instead, you can navigate through the phone using the classic keyboard. You'll also get access to popular apps like YouTube, Google Maps and Google Search. You can even download social media apps like Facebook and Twitter.

Robust design

Just like we've come to expect from CAT smartphones, this B35 is incredibly robust. This durable powerhouse has been given an IP68 certification, which means that the phone is dust and water-resistant. It can even handle a 1.8m drop on concrete!

That's not all! The CAT B35 also meets the military standard 810G. This means that the phone will continue to work in extreme weather conditions. The phone can handle temperatures anywhere between -25 and 55 °C. On top of that, the phone can withstand salt, fog and vibrations.

Handy features

Even though this might not be a smartphone, this phone does come fitted with a large number of great features, including a micro-USB port, Bluetooth 4.1, GPS and GLONASS, an FM radio, 4GB of storage space, a special flash light and a great camera!

On top of that, you'll be able to access the internet just like you would with a regular smartphone. You'll be able to access WiFi internet or use a 4G contract. That way, you'll be able to use apps like YouTube wherever you are!

Compact casing

Because this device doesn't come fitted with a large touch screen, this device feels quite compact. The phone feels comfortable in the palm of your hand and easily fits in your pocket. The 2.4-inch screen may not be very big, but is still large enough for checking texts and using apps like YouTube and Facebook.

Dual SIM

Thanks to its Dual SIM support, the Cat B35 lets you separate your business calls from your personal calls, so you'll be reachable on two different phone numbers at the same time! You'll be able to use both your business and personal SIM card with this phone!
