When you're far away from a cell signal, why not use Satellites to stay in touch?

Higher Ground, a Silicon Valley technology company, introduced the SatPaq at CES 2019. It's a lightweight, clip-on smartphone accessory that enables inexpensive (pay-as-you-go) messaging by satellite. For the 144 million outdoor enthusiasts in the U.S., the SatPaq solves two problems -- the anxiety of not ‘being connected’ and the frustration of having to pay monthly fees even if you do not use the service. SatPaq has recently been named a 2019 CES Innovation Award Honoree in the Wireless Devices, Accessories and Services Category. The SatPaq is the first satellite-messaging product to communicate directly to Geostationary [GEO] satellites for consumer communication. GEO satellites are in a stationary orbit around the Earth and are always in view. The company says messaging over Low Earth Orbit salstellites is SIGNIFICANTLY more expensive than using GEO satellites which in turn require a monthly fee, even when you don't use the service. By communicating with the big GEOs, the SatPaq says they can provide inexpensive, on-demand messaging service that you only pay for when you need it. $249.00 for the SatPaq. Then buy a message package and use them when you need them. There is no monthly service fee.
