Overview

• HarmBlock/HarmBlock+ from SafeToNet is embedded in the operating system to block nude and sexual imagery across the camera, apps, browsers and even livestreams without using the cloud.
• SafeToNet reports training on more than 22 million harmful images and says real‑world accuracy is about 90 percent, claims not yet independently verified in coverage.
• The phone ships as a basic calls‑and‑texts device, and parents can later unlock features, manage app access and screen time, whitelist contacts, set safe zones and view location history.
• Fuse is available exclusively through Vodafone UK at £33 per month with a £30 upfront cost, with broader rollouts planned including Australia where retail availability is slated for August 28 at A$799 with 12 months of HarmBlock+ then A$26.95 per month.
• The launch is framed by growing online‑safety concerns and UK policy efforts, with the Technology Secretary welcoming the device and Vodafone research finding one in five secondary pupils felt pressured to share explicit images.
