Sonnet: World’s Most Advanced Off-Grid Mobile Mesh Network

The Sonnet uses Wi-Fi and long range radio to keep service on your phone when your out of range or off the grid. It also has some life saving features that could come in handy.


Your phone is dependent on the mobile network, and they can’t keep you connected when the mobile network is unavailable or unreliable, such as when you are:

  • Exploring the backcountry: network is unavailable or very sparse coverage
  • Traveling abroad: network unreliable or very expensive to use
  • Attending crowded events: network slow and congested with too many users
  • Encountering a natural disaster: network service disrupted or completely destroyed

On the other hand, walkie-talkies work anywhere. However, they are:

  • Bulky and cumbersome: some walkie-talkies literally feel like bricks that you carry around
  • Complex and unintuitive: A lot of tuning and setup require before you can use it
  • Very low-quality audio only: no text, no images, just bad audio, which often leads to miscommunication
