Remember the last time you needed to send someone a text message and your cell phone couldn’t get service? Like every day! Maybe the system was over crowded, or perhaps the power went out, or maybe you simply wandered off the grid, let’s face it, we’ve all been there. Well then, you may be interested in goTenna, the system that pairs wirelessly with your smart phone to allow your texts to travel over radio frequencies from one goTenna user to another. It works anywhere in the world, so you can explore and roam for free.
