Nice idea, though expensive for what they are when you can for the same money buy a cheap solar charger and basic nokia phone.<p>Also, at least in the UK and I believe europe, if you put any SIM into a phone, nomatter if it has a contract or not. You will be able to call 911/999/emergency services. So you can get a SIM for a each network and have them spare to cover all permutations.<p>Though as I said, nice idea, just expensive for what it is. Realy needs to be sub $30.
