For those who want to enter into satellite communications for as an emergency form of communication, you cant get better than the Delorme inreach SE. it allows 100% possibility of communicating to love ones no matter where you are in the world so long as you have a view of the sky. It works by message only to a mobile number or email (no voice calls) but also gives your position, can track you (every 10 mins) which you can also send to friends and family and even has a sos function so if you do find yourself halfway up the mountain with a broken keg and no phone coverage, you still have the possibility to get rescued. I carry ine with me every where as a back up form of communication which gives me piece of mind no matter where i am. Buying 2 will allow delorme se to delorme se direct communication or you can pair them up with you Iphone or Android phone to check you map location, or send text messages directly from your phone even when there is no coverage. It is reasonably priced unit with VERY reasonable priced monthly plan and i even think they may have introduced a subscription plan that you only pay in a month that you need it. I thoroughly recommend this to everyone whos has even been in a situation without cell phone coverage, not just avid explorers.
