What is LocalMesh?
LocalMesh is an emergency communication network built by volunteers across the UK. When mobile networks fail or internet goes down, LocalMesh can provide an alternative way to stay in touch.
Using LoRa (Long Range) radio technology, you can send text messages to family, neighbours, and your community – completely independent of mobile masts, internet providers, or mains electricity.
Built on MeshCore technology – an open-source protocol that lets messages hop across a decentralised network of volunteer-run repeaters.
The network grows as more people join. Every new participant and repeater extends coverage and strengthens the network for everyone.
How it works
- A small radio device pairs with your smartphone via Bluetooth
- Messages hop between devices until they reach their destination
- Works without internet, mobile Signal, or mains power
The network is free to use
No service provider, no subscription fees, no hidden charges.

Volunteer-maintained

Coverage depends on participation
Note: Your only cost is the radio hardware itself. LocalMesh is volunteer-run and open-source – there is nobody to pay for usage.
Why LocalMesh?
Be prepared for when normal communication fails.
Communication that doesn't depend on infrastructure.
Mobile networks can fail during storms, blackouts, or emergencies. LocalMesh works because it doesn't depend on masts, internet, or centralised servers. Devices communicate directly with each other.

LocalMesh is about preparedness, community, and independence – building a backup network together.

A network that's Growing

From London to Edinburgh, from rural villages to city centres, repeaters are being installed that link communities together.
LocalMesh coordinates this effort and helps people get started with emergency radio communication.
