In reply to rogerwebb:
I have a DeLorme inReach SE, I got it earlier this year for a solo trip to Sarek in Northern Sweden. I've used it for a couple of weekend trips to Cairngorm before I went and the two weeks in Sweden. It plots my position on my webpage which my family have access to. I sent texts form Sarek to the UK and received text from them, so everything worked as it should. I didn't feel the need to press the red panic button so I can't say how that function worked. I'm on the lowest tariff so don't get weather forecasts and haven't downloaded any maps so also can't comment on those. It's $11 a mouth but I can suspend that on a month by month basis if I wish.
I used a small Choetech solar panel to charge it up every three or four day once it had gone down to 75% of fully charged, this took about an hour. Having fallen over crossing a river I can confirm it is waterproof. Friends can only text you via your webpage which you have to give them access to before you go off into the wilderness. Clip it to your rucksack and go, so far very pleased with it.
