DeLorme InReach SE, though there are newer models now. Direct satellite texting from anywhere on earth and it works way better than satellite phones for a fraction of the cost. Send text or e-mail to any smart phone or computer or other InReach. I have used it in deep forest loaded with wet snow in deep canyons of the North Cascades, under heavy old growth trees in rain on the Olympic Peninsula, plus Canadian Rockies, Northern Saskatchewan, Yukon, Cape Hatteras, etc. Best wilderness communication device in my lifetime thus far. Mine was about $400 at REI I think, plus a monthly subscription of $15 (?).
I don't bother with phone in iffy country, just take the InReach. It sends a lat/long location and mark on Google earth with each message, showing the spot from which the message was sent. Compose message at the time, such as: Two flat tires, bring a spare here; I am camped two miles from where we planned; my sleeping bag is lonely...
I have my cell phone along in my vehicle and will check to see if it works but don't count on it.
