HMD Global has unveiled the HMD Fuse, its latest smartphone designed specifically for children. According to the company, it is the world’s first phone that can stop children from filming or sending nude content. It also prevents user from viewing or saving nude or sexual images even during livestreams through HarmBlock+ with HarmBlock AI from SafeToNet.
The device aims to address growing concerns among parents about online safety, especially as issues like cyberbullying and harmful digital exposure continue to rise.
The development of the HMD Fuse was guided by “The Better Phone Project,” an HMD initiative that gathered feedback from over 37,000 parents and children. Insights showed demand for a smartphone that could strike a balance between safety and functionality, as many existing solutions were either too restrictive or too vulnerable to online risks.
“This is more than a product,” said James Robinson, vice president of HMD Family. “It’s a safety net, a statement of intent and a response.”
HMD Fuse – Pricing and Availability
The HMD Fuse is available in a single Noir colour option. It has launched in the UK exclusively through Vodafone UK, priced at £33 per month (with an upfront cost of £30).
The smartphone will be available both in Vodafone retail stores and online via vodafone.co.uk/family.

HMD Fuse – Core Technology and Features
At the heart of the HMD Fuse is HarmBlock+, an AI-powered safety system built directly into the phone’s operating system, making it tamper-proof and impossible for users to bypass.
Key highlights of HarmBlock+ include –
- On-Device AI -The HarmBlock AI works locally on the phone, operating offline across all apps, camera functions, websites, and messages.
- Privacy-Focused – Since all processing happens on-device, no photos, videos, or browsing history are shared externally.
- Content Blocking – Trained on over 22 million images, the AI automatically detects and blocks nude content, stopping it from being captured, displayed, or transmitted.
“HarmBlock Plus can’t be removed, tricked, or worked around,” said SafeToNet founder Richard Pursey. “It doesn’t collect personal data. It just protects every time, across every app, including VPNs, with zero loopholes.”
Parental Controls and Adaptable Design
The HMD Fuse also features an extensive parental control system that allows for:
- App Management – Parents can approve or block apps, set daily usage limits, and schedule screen-free times (e.g., bedtime or study hours).
- Location Tracking – Includes real-time tracking, location history, and safe-zone alerts.
- Communication Safety – Parents can whitelist approved contacts for calls and messages.
The phone is designed to grow with the child. Parents can initially configure it as a simple phone limited to calls, texts, and location tracking, then gradually enable more features, like music apps, controlled web access, and messaging as the child matures.
In terms of design, the HMD Fuse shares specifications with the HMD Fusion and comes with two interchangeable “outfits,” one of which features a foldable LED light ring around the camera for selfies.
