Rugged phones

Reliable Protection in Extreme Conditions

Mobile phone manufacturers have not overlooked those who lead an active lifestyle or whose professional duties involve working in challenging environments. If you see yourself in this description, Sigma mobile’s rugged phones are designed specifically for you. They are reliable, user-friendly, and certified under international IP68 and IP69 protection standards.

Dust and Water Resistance

Rugged phones are distinguished by their absolute dustproofing and strong water resistance, allowing brief immersion up to 1.5 meters deep. The casing is manufactured using dual-molded plastic and rubber technology, ensuring high-level sealing. Unlike touchscreen smartphones, which struggle to register touch with wet fingers, button-based rugged phones can be used even with dirty hands without compromising functionality.

Powerful Batteries

Sigma mobile rugged phones come with high-capacity batteries, providing up to 13 hours of continuous operation and 14 days of standard usage with regular calls. This battery life has been tested in-house, ensuring reliability for users in environments where daily charging isn’t possible—such as remote areas without electricity.

Complete Functionality

Sigma mobile rugged devices are simple to use, ergonomically designed, and feature-packed. They offer high-quality communication through dual SIM support, large screens for convenience, and security settings for enhanced protection. When selecting the ideal device, consider these additional features:

• Multimedia tools (players, camera, voice recorder, FM radio, etc.)
• Organizer functions (alarm clock, stopwatch, calculator, calendar, notes, e-book reader, etc.)
• Speed dial
• Keyboard backlighting
• SOS function for emergency calls
• Powerbank functionality
• Built-in walkie-talkie
• Dedicated flashlight button
