Messaging when the network isn't there
Practical ways to connect your group, wherever your plans take you.
"No signal" isn't one situation. A festival that has flattened the local cell site, a blackout working its way through backup batteries, and a valley that never had coverage are three different problems, and the useful answer differs for each.
Find a setup that works for your group, learn how messages travel and see what to prepare before you go. Each guide explains the useful limits alongside the possibilities.
Texting with no serviceUse nearby phones to keep a conversation moving when cell service is unavailable.Power outages & disastersHome internet goes instantly, cell sites run down over hours. What to expect, and how to keep a street talking.Hiking & backcountryKeep your party in touch along the trail and around camp, with optional LoRa radios for extra reach. Carry a separate device for contacting rescue services.Festivals & crowdsFull bars and nothing sends. Why crowds break the network, and why they are the best possible conditions for a mesh.
If the hop-by-hop idea is the part you want to see, the browser demo runs it without installing anything: knock out a cell tower, then walk a message across a crowd.
