We did the Salkantay glamping trek with Quechuas Expeditions this year. Their website has a whole page about satellite phones. When someone in our group was injured on the trail at dusk and could barely walk, we found out our guide didn't have one. The rest of the trip matched that pattern: no hot water and no firewood on a freezing first night, one chicken wing per person plus bread for one dinner, one pancake each for breakfast with protein as an upcharge, and several meals without enough meat for everyone to get any. We asked to end the trip early and were refused. Afterward we asked politely for a partial refund and were refused again. Our guide was kind. The company isn't. Whoever you book with, get these in writing before you pay: The guide carries a working satellite phone Exactly which meals and fees are included What happens if you need to leave early Happy to answer questions.
