Unbroken Coverage with Two-Way Satellite Connection

When traditional cellular networks fail, the CAT S75’s built-in two-way satellite feature keeps you in touch with SOS alerts, text messages, and GPS coordinates. Through its global L-band satellite link—operable in any remote location outside of cell range—you can reach emergency services or teammates at the push of a button. The interface automatically switches from 4G/5G to satellite when needed, so you never miss critical messages. Whether you’re lost on an ice cap, navigating a desert highway, or coordinating disaster relief, this phone transforms from “no signal” into your lifeline.

Rock-Solid Construction: Military-Grade Durability

CAT’s legacy of rugged devices continues with the S75’s MIL-STD-810H certification and IP68/IP69K ratings. Its reinforced composite frame endures multiple drops from up to two meters onto concrete, while sealed ports and hydrophobic nano-coatings repel water, dust, and mud—even under high-pressure, high-temperature jet sprays. The 6.5-inch HD+ display, protected by Gorilla Glass Victus, resists scratches and impacts, remaining readable in direct sunlight. Glove-friendly touch sensing and tactile buttons ensure operability in rain, snow, or with thick work gloves. This isn’t just a phone—it’s a tool built to survive the harshest environments.

Dual-SIM Flexibility for Global Travelers

Juggling work and personal lines, or switching carriers across borders, has never been easier. The CAT S75 features dual nano-SIM slots—both factory unlocked—so you can maintain local data plans overseas while keeping your home number active. The software’s intuitive SIM manager lets you assign calling, messaging, and data priority per slot. Roam seamlessly in Europe, the UK, or any unlocked region without expensive roaming fees. For professionals who work internationally, this phone removes barriers to connectivity and keeps your costs predictable.

Factory Unlocked for True International Freedom

Unlike carrier-locked devices, the CAT S75 arrives ready for any GSM or CDMA network worldwide. Insert a compatible SIM, and you’re online—no tedious unlocking procedures or hidden fees. Frequent flyers, field engineers, and global aid workers benefit from instant access to the best local carriers. The phone supports 4G LTE bands used across Europe and the UK (and many other regions), as well as fallback 3G for remote areas. You choose your network; the phone adapts.

Immersive Display and Reliable Touch Controls

At the heart of the CAT S75 lies its 6.5-inch HD+ TFT screen, offering bright, crisp visuals even under a blazing sun. The 20:9 aspect ratio balances compact handling with ample viewing area for maps, satellite feed indicators, or video calls. Adaptive brightness and color profiles ensure legibility in night-vision settings, while a glove and wet-touch mode lets you swipe, tap, or scroll even when your hands are cold or damp. Whether you’re reviewing satellite text threads or browsing schematics on site, the display keeps up without false inputs or lag.

Long-Lasting Battery for Endurance Missions

Powering both high-bandwidth cellular and satellite radios demands serious energy reserves—and the CAT S75 delivers with its 5,500 mAh battery. Expect two days of mixed usage on 4G, or extended standby when primarily in satellite mode. Fast-charging via USB-C brings you from zero to 50 percent in under 30 minutes, while wireless charging adds desk-side convenience. Intelligent power modes let you throttle background apps, disable non-essential radios, or schedule deep-sleep intervals, maximizing uptime during multi-day treks or emergency operations.

Impressive Performance and Storage

Equipped with a robust octa-core processor and 6 GB RAM, the CAT S75 handles mapping apps, satellite communication clients, and productivity suites without stutter. Its 128 GB internal storage—with microSD expansion up to 1 TB—accommodates offline maps, satellite logs, photos, and critical documents. The Android-based OS remains fluid under heavy multitasking, whether you’re toggling between GPS navigation, field-report uploads, and satellite text threads.

Camera System for Documentation and Diagnostics

Beyond navigation and calls, the S75’s 48 MP main camera and 8 MP ultra-wide lens capture high-resolution evidence—damage assessments, geological surveys, or team activities. Night-mode algorithms brighten low-light scenes, while the dedicated macro lens documents small components or manufacturing blemishes. Geotagging embeds GPS coordinates in every image, simplifying audit trails and location-based reporting. A front-facing 16 MP camera ensures video-call clarity when coordinating with remote teams or conducting tele-medicine check-ins.

Secure, Enterprise-Grade Software Features

Security matters when your device contains sensitive coordinates and mission-critical communications. The CAT S75 supports PIN, pattern, fingerprint, and facial unlock, and includes a hardware-backed Trusted Execution Environment (TEE) for secure key storage. Over-the-air (OTA) updates deliver Android security patches promptly, while enterprise MDM (Mobile Device Management) compatibility allows IT teams to enforce policies, push configurations, and remotely lock or wipe lost units. Google Play Protect and pre-installed safety apps provide further peace of mind on high-risk deployments.
