Built for the good times

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

Excellent connectivity

The Crosscall CORE-S4 features dedicated network bands for 4G connectivity. These bands cover most European providers and all French providers. At home or in the office, the CORE-S4 connects to the Wi-Fi network (802.11 b/g/n 2.4Ghz) so that the mobile data plan remains intact. Finally, through the KaiOS operating system, several popular apps are installed on the CORE-S4 by default.


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

Ergonomic design of the Crosscall CORE-S4

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

Replacement for DECT

The Crosscall CORE-S4 is optimized to replace landline and cordless phones in the enterprise. Until now, companies used cordless phones to make calls from one service/department to another. The 300 m range of these phones limited mobility and use within the company. The Crosscall CORE-S4 takes over the main functions of the DECT (Digital Enhanced Cordless Telecommunications). Thanks to VOLTE and VOWIFI technologies, you have mobility without interrupting your communications. For example, when you leave an area with Wi-Fi coverage, your CORE-S4 immediately switches to 4G. Coupled with the X-DOCK’s wireless charging system, your CORE-S4’s battery life is guaranteed.
