Get on a plane and then a bus and then a microbus or some kind of informal rural transit, go as far as you can into the mountains or the desert or the jungle and take with you one of these and a mikrotik router and a source of solar power. You won't be able to get much of a cell signal - or it's slow or expensive - and community access to Wikipedia and health-care information could be the most useful treasure you bring with you, without needing to worry about the kind of devices they run.
