There is no doubt everyone has had a time where a lack of signal meant they couldn’t send out a crucial text message. goTenna looks to combat that problem with its portable antenna device. The sleek and small device wirelessly pairs with your smartphone so you can send text messages directly with others even when you don’t have service, without requiring any other element such as satellites or Wi-Fi. It works anywhere on the planet with anyone else who has the device, allowing the user to connect privately and devoid of subscriptions or fees. The goTenna is available for a special pre-order discount price of $149 USD per pair, while prices will increase to $299 USD per pair when the discounted units sell out.
