goTenna Mesh is the first 100% off-grid, mobile, long-range consumer-ready mesh network. The device pairs with your smartphone to enable communication even when you don’t have service. There’s absolutely no towers, routers and satellites required.
With goTenna Mesh you can send text messages and share GPS locations on offline maps with others. Chat privately in 1-to-1 or group conversations, or broadcast to any other goTenna Mesh device up to several miles or kilometers away all without using towers, routers or satellites.
