Your CORE-S4 comes with 4G and Wi-Fi and is powered by the KaiOS operating system.
KaiOS, for keypad feature phones
With the KaiOS app store, many of the most popular apps come already installed on your CORE-S4.
This means you can access Facebook and WhatsApp as soon as you start your phone.
Want even more? Go to the KaiOS store to find a wide range of downloadable apps.
The phone that offers both 4G and WI-FI
Touch and voice control
The CORE-S4 has a voice recognition button at the centre of its monoblock keyboard. Tap the button to use voice commands with your phone. Searching the internet, texting, looking up videos on YouTube, etc. have never been easier: just speak, and it follows your commands!
Optimised to replace your corporate wireless telephony
In the past, wireless phones were used to make calls from one workstation to another within a company on dedicated infrastructures, in addition to the 3G/4G and WiFi networks already available, thus limiting mobility and usage close to the company. Those days are over. Don't miss any more mobile calls and gain in reactivity.

« After a discussion with my operator, who showed me the features available for communications in my company, we decided to equip all our employees with a CORE-S4 with its X-DOCK charging station. This solution allowed us to simplify the management of the fleet, i.e. centralized configuration of user groups and their lines, and on the device side, use on our corporate WiFi network and less breakage thanks to the phone's resistance. What makes you different? The fact that you are a French brand capable of offering attractive products in terms of both promises and equipment costs, and your ability to support us throughout the project. »
The CORE-S4 is quite simply ideal for outdoor use.
Compact and extremely robust
American military standard MIL STD 810H
The CORE-S4 has passed 15 of the US military standard MIL STD 810H tests with flying colours, including the drop test from two metres onto concrete and the temperature tests. Do you work in the steel industry? Or maybe in cold storage rooms? Look no further! The CORE-S4 can withstand temperatures ranging from -32°C to +60°C.
Waterproof and impervious to microparticles
Waterproof and impervious to microparticles
In compliance with standard IP68, the CORE-S4 also withstands immersion to a depth of 2m for 30 mins.
Designed for use in harsh conditions, the CORE-S4 with its monoblock keyboard can be washed with soap, whilst a microperforated GORE membrane protects your microphone against water infiltration.
With its single circuit numeric keypad and built-in protective grilles on the ear speaker and hands-free speaker, the CORE-S4 never lets dust in.
It’s an ideal design if you are involved with woodwork, where sawdust can get in between the keys or into the speakers and eventually damage your phone.
Sealing caps are also included to ensure that your phone is completely protected from all other microparticles.
At the start of day, I plug my CORE-S4 into the X-CAR PRO to charge the battery for the whole day. I usually have about 7 or 8 visits a day and the phone lets me stay in touch with my clients all day long. With the CORE-S4 I can keep in close contact with the clients. It also helps me to keep in touch with the office, which is key, given that our work is all about relationships between people. So it’s very important to have a long battery life. Also, the native apps mean I can go online or access some entertainment without worrying about running out of charge, which is really important to me. It means that I can sometimes take a break during the day, thanks to CROSSCALL’s long battery life
Durability is essential…
Durability, reliability and repairability are its fundamental elements.
Designed with our core values in mind, the CORE-S4 embodies our commitment to durability and to building a phone you can rely on, without limiting its usability. It also has a three-year warranty like all the products in the range.
Buttons remain waterproof after 400,000 presses
In other words, 365 presses every day of the warranty period.
A BATTERY THAT LASTS
« I work in an environment that is very noisy and exposed to intense heat. When you melt metal, you generate a lot of dust. This dust is very fine and penetrates the phone’s speaker grille in the space of a few days, completely clogging up the membrane so it can no longer vibrate and therefore emit sound. To cope with these very difficult conditions and combat this issue, we decided to use the CORE-S4. It’s also resistant to all liquids, which is a huge plus since there's also a lot of oil and grease on site. Being equipped with Crosscall devices means we don’t need to replace our phones as often, and the daily management of our pool of mobile phones is much easier. From the feedback I have received from employees with the phones, I can confirm that Crosscall products are reliable »
They are certainly durable and they are also repairable !
Repairability is a key part of a product’s durability, and important work has been carried out throughout the design process of the CORE-S4 so that its components can be easily replaced by accredited repair centres.
The camera is easy to remove.
When opening the phone, there's no glue to remove, only screws.
The battery is screwed in (not glued).
The glass is not glued to the screen.
Spare parts available for 10 years for the CORE-S4
The reduced amount of plastic is great for the environment.
The sustainability of the CORE-S4 can also be seen in its packaging. Creating eco-friendly packaging is one of the brand's commitments and is part of our CSR (Corporate Social Responsibility) policy.
