I can use my simple phone for $73 a month where I live
- pay $80 for 20gb internet
- carry a camera that can take decent pics
- mp3 player that can hold enough music
- carry a map and compass
- notepad and a pen
I can use my smart phone for $80 a month with 6gb bandwidth
I normally use my smart phone because instead of carrying a backpack with all my stuff I carry it in my pocket, although for going 10km+ around where I live I take my simple phone (and everything else) because there is no network and I'd break/lose them one at a time than all gone at once in the middle of nowhere.
I am considering buying an satellite phone for use where I bring my simple phone so I can actually use it and will be able to phone for help if I ever needed to.
