May I hijack to ask if someone can hack together a cheap solution for this? My beloved dog will be flying in the cargo hold of an A380. I will be seated above in the passenger section. 15 hour flight to Australia. I have to drop him off in his kennel four hours before departure at the freight office at the airport. They will take him to the plane. After the flight, he will be picked up and driven about 10 miles away to a quarantine facility. I would like to build something to put inside the kennel which will allow me to track its location at the freight office and then confirm he's been brought on board. Then at landing, I want to track the kennel from plane to quarantine. Note this is in a different country as departure. I'm thinking of getting a used Nexus phone and a Project Fi SIM (so I can have data overseas too). However this will be rather clunky and I'd rather not put a bunch of batteries in his kennel for a flight. Any ideas??
