The SAMSUNG a657 is one tough phone. It has a rugged bar design with a rubberized grip and attaches easily to a belt. It’s also certified to meet military specifications for dust, shock and vibration – as well as heat and cold – so it can handle anything you can dish out. But inside, the a657 is as sophisticated as any other SAMSUNG mobile phone. It even has a very handy built-in flashlight. Does that work for you?
