Have now received my Delorme InReach Satellite Communicator, using the Iridium satellite network but $1000 less than a Satphone because it only uses text or email, not voice. Who wants to answer the phone anyway! You can post directly on Facebook also showing your position.
The access fee is $17 per month and .75 cents per text. You can get a 72 hour weather forecast from Ocens Spotcast for your local area delivered via satellite on a $80 per annum plan.
