Tallinn, Estonia – March 1, 2026. The marine industry is becoming increasingly connected. Vessel owners expect real-time visibility, marinas require remote diagnostics, and fleet operators demand cross-border reliability. Yet delivering seamless global IoT connectivity — especially across diverse coastal regions and international waters — remains a technical and operational challenge.
Today, VoltSense announces a partnership with 1oT to provide worldwide cellular IoT connectivity for its marine monitoring platform.
Enabling truly global marine monitoring
Through 1oT's global IoT coverage, VoltSense devices benefit from:
