A Handy Smartphone Accessory That Let's You Send Texts Without Cellular Coverage



We are living in the age of smartphones. There are even some people who can claim that they won't be able to go a day without them. We use our smartphones primarily to communicate with our loved ones and keep them updated with the goings-on in our lives. So it is vital that we are always wired and connected. Unfortunately, there are instances wherein you will be stuck in an area where there is poor or nonexistent cellular or data network. In this case, your smartphones will be deemed useless.

goTenna is a handy pocket-size communication accessory that enables smartphones to communicate with each other without the need for cellular or data network — even in Airplane Mode. So there is no need to worry about being off-grid, you can still remain connected.

goTenna works by pairing with your smartphone thru Bluetooth LE. It only needs to be within 20 feet of your smartphone 
in order to work. It uses low frequency signals (151-154 MHz) to send off text messages through a proprietary app to other goTenna users for free, and it claims to have a range of up to 50 miles depending on the terrain. goTenna can also be used to send detailed offline maps of your current location free of charge. It also offers location pinging and end-to-end encryption. As a safety feature, all messages will be deleted when another smartphone tries to connect to it. goTenna can only be connected to one smartphone at a time, which is a major drawback.

It measures 5.8 inches in length and weighs 2 ounces. When the antenna is extended, the length extends to 8 inches. Its casing is made of high-grade, durable metal, nylon, and silicone. It is designed to be water-resistant and dust-tight. Inside, you will find a circuit board, radio chips, a custom antenna, and a lithium-ion battery, which can be recharged using any micro-USB cable.
