This Handy Device Will Let You Send Text Messages Even After The Grid Crashes

Communicate without the need for any central connectivity — no Wi-Fi, cell towers or satellites needed. The gadget uses long-range radio waves — between 151-154 MHz — to send messages to other goTenna devices within its range. Depending on the surrounding terrain and elevation, the device can send messages up to 50 miles away. In the city, the range shrinks to roughly 1 mile.
