Slopend has a Satellite phone (Garmin inReach Messenger)! Very nice to have with you on trips and expeditions, so you always know you can call for help.
The different functions of the inReach messenger are explained in the manual. Before using it, it is wise to read through the regulations as well (unfortunatly the manuel and instructions have not been translated yet). Once you rent the Garmin you will get more information from the contact person from the board.
