GoTenna 2-pack | Offline Bitcoin Transactions

Pair to your phone and create your own signal. goTenna Mesh lets you send texts and GPS locations, but more importantly, the upcoming txTenna app from Samourai Wallet will allow you to make Bitcoin transactions with absolutely no internet connection required. Revolutionary mesh networking privately and automatically relays messages through other devices to extend beyond point-to-point range; the bigger your network, the stronger your communications. As more and more people join the mesh network, the more anonymous and decentralized it becomes, allowing Bitcoin transactions without relying on an ISP at all.
