Why choose a rugged mountain phone?
The mountains are an adventure playground as fascinating as it is demanding. Between sudden weather changes, rugged terrain and isolation, every high-altitude excursion involves risks. A rugged mountain phone is not just an accessory, but a real safety tool.
Whether you're a casual hiker or a seasoned explorer, nature is no picnic. All it takes is one false step, fickle weather or a flat battery to turn a beautiful day into a real challenge. The right equipment makes all the difference, and among the essentials, a reliable all-terrain smartphone is a must.
Crosscall, the French brand of outdoor smartphones, offers two models for adventurers: the STELLAR-X5ideal for hiking and photography, and the STELLAR-M6designed for rugged explorers.
STELLAR-X5 : the rugged phone for the mountains

Resistance designed for extreme environments
Beyond its photo and video qualities, the STELLAR-X5 is designed to stand the test of mountain life.

An eco-designed approach to respect the environment
From the outset, the STELLAR-X5 has been designed to reduce its environmental impact.
