Going ‘off the grid’ may be a thing of the past with the introduction of new technologies that will allow you to text without the need of cellular or wifi connection. The latest to try their hand at it is goTenna, which effectively turns back time and turns your iPhone or Android device into a walkie-talkie – using good ol’ fashioned radio signals to transmit text messages to other goTenna owners. I’m going to assume this is designed to be used in times of actual need, i.e. while out on a camping trip or overseas outside of your local network, and not during the 45 seconds you’re in the elevator or driving through an underground carpark. Though it might also be handy during those frequent signal-killers known as any summer music festival. Want more technical info? Watch the video above or head to goTenna’s website, where you can also pre-order your own device.
