Isaid Radios H33 – Waterproof Rugged LTE + Wi-Fi Walkie-Talkie

True Nationwide Range. Zero Limits.

Experience instant, uninterrupted communication with the Isaid Radios H33. Powered by advanced Push-to-Talk over Cellular (PoC) technology, the H33 completely bypasses the distance limitations of traditional two-way radios. Whether you are coordinating a fleet across the country, managing a job site, or preparing for emergency grid-down scenarios, the H33 delivers crystal-clear, lag-free audio anywhere in the USA.

Multi-Carrier Reliability & Wi-Fi Failover

Equipped with specialized IoT SIM cards, the H33 doesn't rely on a single cell provider. It seamlessly scans and connects to the strongest available major LTE network (including Verizon, AT&T, and T-Mobile). If all cellular towers are compromised, the H33 automatically utilizes its built-in Wi-Fi Backup feature to keep you connected.

Rugged, Waterproof, and Ready for Anything

Built for the harshest environments, the H33 features an upgraded rugged exterior and an IP67

 Waterproof rating. Not only can it withstand heavy rain and direct water spray, but it is also designed to float—making it the ultimate communication tool for marine, outdoor, and industrial applications.
