Globalstar has over 40 low-earth-orbit satellites around the planet. What better way to put them to use than to send your tweets? The company’s consumer-friendly Spot service doesn’t let you talk—get this, it doesn’t even let you receive messages—but you can send GPS coordinates and messages to family members and followers for cheap. (Like Globalstar’s voice service, Spot doesn’t reach the poles or parts of Africa.)
Spot Connect works via Bluetooth to relay your SMS, Twitter, and Facebook messages from an Apple or Android phone. Weighing 4.9 ounces, the Spot Connect’s battery will last for about 180 messages or five days. The device also works as an emergency locator beacon, but hopefully that won’t come up. In day-to-day use, it’s currently the least expensive way to communicate by satellite around.
PRICE: $169. SERVICE PLAN: $99 per year for basic service, plus $.50 per message (bundled plans for messages available). RENTAL FEE: $50 per week.
