I hate that I have to post this question but my job is being rather unreasonable about the 4 days I will be completely out of pocket because I will be climbing Kilimanjaro (the whole climb will take about 8-10 days but due to weekend and holiday it'll just be 4 days). Does anyone know whether I can buy a satellite phone or get a SIM card or something (my phone is not unlocked) at the airport so that I can be reached in case of an emergency while I'm hanging off the side of the mountain?
Any advice would be much appreciated.
