Quick Take: With a handset selection dominated mainly by Nokia and Motorola phones, AT&T Wireless hasn't introduced many Samsung phones to its lineup. But with the rollout of the Samsung SGH-X426, AT&T customers have an additional choice, and Cingular has a similar version, the. Small (3.3 by 1.8 by 0.8 inches), light (2.8 ounces) and clad in basic Samsung silver, the X426 somewhat resembles the for T-Mobile service. However, while all have a 65,000-color main display, the AT&T and Cingular models don't stack up feature-wise. There's no multimedia messaging and no external display, so you're forced to open the handset to see the caller's number--a rare trait in flip phones these days. Other features are basic: a 500-name phone book, 40 polyphonic ring tones, a calendar, a to-do list, a memo pad, and a WAP 2.0 wireless Web browser. Furthermore, the dual-band (GSM 850/1900) mobile is not a world phone. It's well priced at $119.99 or less with service, but those wanting a full-featured cell phone should look elsewhere.
