Samsung SGH-T639

When is a 3G cell phone not a 3G cell phone? Apparently, when it's the Samsung SGH-T639. Though the handset has long been rumored to be T-Mobile's first 3G device, Samsung is not listing wireless broadband among the SGH-T639's specifications. But on the other hand, T-Mobile is indeed pushing the handset as a 3G device, which is odd considering that T-Mobile has yet to launch its 3G network. When we asked T-Mobile representatives for a clarification, they responded by saying the SGH-T639 is a 3G-capable handset that is positioned to be among the first devices to take advantage of a future UMTS network. Well, that explains it.

But 3G or not, the SGH-T639 is a megapixel camera phone with midrange features like Bluetooth and a music player. Its flip-phone design is taken straight from Alltel's Samsung Hue (or maybe it's the other way around) and its call quality was decent.

Design
As mentioned earlier, the SGH-T639 shares its design with the Samsung Hue SCR-R500. Both handsets show a two-toned design, though the SGH-T639's replaces the Hue's red stripes with dark blue. The SGH-T639 also shares the Hue's dimensions (3.72 inches by 1.95 inches by 0.66 inch; 3.34 ounces) while its vertical external display, camera lens, self-portrait mirror, and side controls are unchanged as well. See our Hue review for more information.

The 2.12-inch internal display (262,000 colors; 220x176 pixels) remains just as bright, but it allows you a few more editing options. You can alter the font, size, text, and type, and you can change the backlighting. Also, unlike the Hue you can change the font color on the external display. The navigation controls and keypad buttons also show a similar design, though T-Mobile altered the shortcut controls. Instead of a voice-dialing control and a speakerphone shortcut, the SGH-T639 has a Web browser key and a dedicated control button for accessing a user-programmable shortcuts menu. Otherwise, the navigation array is the same. There's a four-way toggle with a central OK button, two soft keys, the Talk and End controls, and a Clear key. The keypad buttons also show no differences from the Hue. They're large and brightly backlit but equally flush with the phone's surface.

Features
The Hue has a 1,000-contact phone book (twice as large as on the Hue) with room in each entry for five phone numbers, two e-mail addresses, two Web addresses, an instant messaging handle, a nickname, a birthday, a company name and job title, two street addresses, and notes. You can save contacts to caller groups, and for caller ID you can assign a photo and one of 21 polyphonic ringtones. Just remember the photo doesn't show up on the external display. The SGH-T639 also supports T-Mobile's myFaves feature, which gives you unlimited calling minutes to any five numbers on any network, even landlines. And for safekeeping, you can sync your contacts with T-Mobile's servers.

Basic features include a vibrate mode, text and multimedia messaging, an alarm clock, a calendar, task list, a notepad, a calculator, a voice recorder, a world clock, a stopwatch, a timer, a unit converter, and a tip calculator. Bluetooth is also onboard, as is a speakerphone, though the SGH-T639 lacks the voice commands found on the Hue.
