Review: Samsung Rugby III for AT&T
The Rugby III is a jack of all trades, but master of none. If you're looking for a basic handset that can withstand some abuse, it manages to accomplish that with ease. Nearly every other feature, however, earns a "B" at best.
The biggest detractor is call quality. It's simply not good enough, not for a device that is mostly likely to be used as a dedicated voice phone. Further, as a PTT device, the speakerphone should be incredibly loud. It isn't, not by a long shot. Battery life is stellar, though. The messaging and media features are on par with other devices in this class, which is to say they are rudimentary at most.
For AT&T customers who can't switch to Sprint and need a PTT-capable device, the Samsung Rugby III is serviceable, but not much more than that.
