Gotenna Phone Booster — It’s called the ‘goTenna,’ and this little antenna syncs to a phone to give text messaging capability off the grid. It works much like a walkie-talkie — to use it, you must have a partner who also has a goTenna.
The goTenna lets you send and receive texts via a low-frequency radio signal with a cited range up to 50 miles. $299 for a pair when they come to market this fall.
