The 4G Mobile Phone

The CORE series is being expanded with a new product, the CORE-S4. This new Crosscall CORE-S4 is a compact, strong and simple phone with buttons, in combination with the apps of a smartphone. The CORE-S4 simply gives durability and longevity in one device that is compact, strong and simple and even compatible with the X-LINKTM mounting and charging system. Plus a 4G connection and access to the most popular apps.

Great connectivity

A 4G connection, WI-FI and access to the KaiOS Store! The CORE-S4 has special network bands for 4G connection. These bands cover most European carriers and all French carriers. At home or in the office, the CORE-S4 connects to the WiFi network (802.11 b/g/n 2.4Ghz) so that the mobile data subscription remains intact. Finally, several popular apps are installed on the CORE-S4 by default via the KaiOS operating system.


The CORE-S4 comes with a 3-year warranty and features a durable design. With a 2300 mAh battery and IP68 certification, this device can withstand bumps and drops. In addition, the CORE-S4 is waterproof in fresh, salt and chlorinated water, and dustproof.

Ergonomically designed

The CORE-S4 offers optimal ease of use and is compact (140x62x14.4 mm) and light (153 g). The bright screen and monoblock backlit keyboard ensure smooth and pleasant use, even with gloves. A 100 dB loudspeaker makes conversations (including hands-free) clear and audible, even in a noisy environment. The CORE-S4 is compatible with X-LINKTM technology.

The new DECT

Replacing wired and cordless business phones. Until now, companies have used cordless phones with a range of 300 metres to call from one department or phone line to another. This not only limits how much the technology can be used, but also the mobility within a company. The CORE-S4 includes the main features of DECT (Digital Enhanced Cordless Telecommunications). Thanks to the VOLTE and VOWIFI technology, you can be mobile without interrupting your communications. For example, when you leave an area covered by WiFi, your CORE-S4 switches directly to 4G. And the X-DOCK cordless recharging system means your CORE-S4’s battery life is guaranteed.
