The mobile that combines 4G and WI-FI

TODO
The CORE-S4 integrates network bands dedicated to 4G connections. These bands cover French operators as well as most European operators.
At home or in the office, your CORE-S4 connects to your WIFI network (802.11 b/g/n 2.4Ghz) and saves you money on your mobile data plan.
By combining 4G and WIFI, you can use your CORE-S4 as a modem, enabling other devices and people around you to benefit from fast 4G Internet access.
Thanks to the dual SIM slot, you can switch from one SIM to the other in a single gesture, or temporarily subscribe to a local rate plan abroad.

Optimized to replace your corporate wireless telephony

Until now, wireless telephones have been 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 calls on the move, and improve your responsiveness.

Mobile fleet manager

"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 has enabled us to simplify management of the fleet, with centralized configuration of user groups and their lines, and on the handset side, use on our corporate WiFi network and less breakage thanks to the phone's resistance. What makes you different? The fact that you're a French brand capable of offering attractive products both in terms of promises and equipment cost, and your ability to provide us with long-term support throughout the project.

Auxiliaire de vie à domicile

At the start of the day, I connect the CORE-S4 to the X-CAR PRO , so that my battery maintains its autonomy throughout the day. I generally have 7 to 8 jobs a day, and the telephone keeps me in touch with my customers throughout the day. The CORE-S4 gives me real proximity to the customer, and also helps me keep in touch with the association, which is essential given the very nature of our business: human relations. That's why it's so important to maintain a high level of autonomy.

Similarly, thanks to the applications natively installed on the phone, I can surf the web or access certain entertainment without worrying about battery life, which is truly appreciable. Sometimes I'm able to fit a break in my day while keeping the Crosscall's autonomy intact.

Sustainability is essential...

Durability, reliability and reparability are its watchwords.

Designed in the quintessence of CROSSCALL values, the CORE-S4, with the same 3-year warranty as all CORE devices, embodies the brand's promise of durability and of a mobile capable of accompanying you over the long term without any compromise on your use.

Christophe

Engineer

"I work in a very noisy environment, exposed to high temperatures. When you melt metal, you generate a lot of dust. This very fine dust enters through the phone's loudspeaker grille and in a few days completely clogs the membrane, which can no longer vibrate and therefore emit sound. To cope with this harsh environment and this problem, we opted for the CORE-S4. They're also impervious to all liquids, which is a big plus since there's a lot of oil and grease on the sites. Choosing Crosscall products has enabled us to replace our phones less frequently, and above all to facilitate the day-to-day management of our mobile fleet.

From the feedback I've had from equipped employees, I can say that Crosscall products are reliable."

TODO

Sustainable, yes, but also repairable!

Repairability being one of the keys to a product's durability, the CORE-S4 has benefited from special care throughout its design, so that its components can be easily replaced by authorized repair centers.

Any modification or change made to your device outside an authorized center will invalidate the warranty. If your unit requires repair, we recommend that you take it to the CROSSCALL after-sales service.
