| Bottom line | The Samsung SGH-T139 doesn't promise much, but it serves its purpose as a low-end phone for making calls. | An example of excellent call quality at a dirt-cheap price, the Samsung t159 excels at the basics, but stumbles on style. | A few quibbles notwithstanding, the powerhouse HTC One is a beautifully crafted, near-ideal smartphone. | Info unavailable | Nokia's Lumia 521 is one of the best bargain smartphones on any platform, but skip it if LTE is of paramount concern. |
