The Real optimum cell phone is........The one you have on you,at the time you need it most!I would like to think everyone on/off,reading,writing on this site,has at the very least,the minimal knowledge to help themselves survive just about Anything disaster or shortcomings related,Without a Comm. device of Any kind!Since just about everyone does have a Cell phone/Comm. device,why not include it,Per "part" of kit?
