Description of the Cat B35 Dual Sim

Cat B35 Dual Sim

This Cat B35 Dual Sim is an extremely sturdy phone, which has surprisingly high functionality for a non-smartphone! The device runs on KaiOS, a special operating system that still allows you to use a number of popular apps!

Of course, this Cat B35 is very robust. You can drop it on a concrete floor from a height of 1.5 meters and it will still work! You can really take it anywhere. This powerhouse can handle even the most extreme conditions.

Military standards

In addition to an IP68 certification for dust and water resistance, the Cat B35 Dual Sim also has a military degree in sturdiness. With the MIL 810G certification, you can drop the Cat B35 from a height of 1.8 meter onto concrete without losing functionality.

This phone can withstand temperatures between -25 and 55 degrees Celsius, and withstand hard vibrations. It is also prepared for salt water, salt fog, and other sorts of humidity. No matter what kind of work you do, this Cat B35 will survive it all.


Usually, non-smartphones don't have access to apps that you can use on a smartphone. With KaiOS, it's different; they have special versions available for a number of popular apps, such as YouTube, Google Maps, Google Search, and much more.

An increasing number of apps are being released for KaiOS. You'll soon be able to use WhatsApp on this phone! Other apps that are available for download are Facebook, Twitter, and many others.

Packed with useful features

This Cat B35 comes with all sorts of features that make it just as good as the average smartphone. You can charge it via a MicroUSB port, listen to your radio via the FM radio, connect the phone to Bluetooth devices, and use GPS and GLONASS.

You can also use mobile internet with this B35. You can connect it to a WiFi network, or you can just use 4G if you have a SIM card that supports it. You'll always be online, even without a smartphone!

Dual SIM

In the B35 you can place not one but two SIM cards at the same time. This means that you can be reachable on two numbers at the same time. Do you have a work SIM card and a private SIM card? No problem! You place both of them in the phone, and you can use them simultaneously!

Handy format

This phone has a 2.4-inch screen and a normal phone keypad, so it's nice and small. Thanks to its thickness, the phone fits comfortably in your hand, but it is still small enough to disappear into any pocket.
