This is done by pairing the device (pictured above) with your smartphone via Bluetooth, which will then turn your phone into a low-frequency radio with a range of up to 50 miles. From there and through an iOS or Android app, it will allow users to send text messages or share your GPS location over a free ad hoc network with other goTenna users.
This means that the person receiving your message will require a goTenna device themselves and be at least within range for it to work. Like we said this could come in handy for hikers and adventurers to tend to wander into remote locations where cell reception might not necessarily be the best.
If you’d like to learn more or place an order, head on over to goTenna’s website where you will be able to purchase a pair of goTenna devices for $150. Right now the company has discounted the device by 50%, so once the offer runs out, it will be sold at $300 per pair.
