Product Overview
The KSUN CT22 is a next-generation 4G Public Network Intercom that combines the instant push-to-talk functionality of a traditional two-way radio with the unlimited range of cellular networks. Unlike conventional walkie-talkies limited by radio frequency range, the CT22 operates over 2G, 3G, and 4G networks — delivering crystal-clear voice communication across cities, states, or even countries, as long as there is cellular coverage.

Engineered with a premium ABS + metal body featuring an electroplated metal bezel, the CT22 offers a sophisticated look with superior durability. Its 1.44-inch high-reflection HD screen remains clearly visible even under direct sunlight — a critical feature for outdoor professionals working in bright environments.

Whether you're managing a logistics fleet, coordinating a construction site, directing an event, or leading an outdoor expedition, the KSUN CT22 keeps your team connected — reliably, instantly, and without distance limits.
