At first glance, the Sanyo SCP-3100 may remind you of a kid's walkie-talkie, thanks to the plastic exterior and the large speaker grille; the phone looks a bit cheap as a result. Its size and heft (3.31 by 1.83 by 1.01 inches; 3.5 ounces) are good for smaller hands, but the clamshell too bulky to slip in a jeans pocket. Though it isn't a big deal, opening the SCP-3100 takes some effort due to a springy hinge, but the phone cradles your ear comfortably. The SCP-3100 also has an extendable antenna.
Open the Sanyo SCP-3100, and you'll be presented with a rather lackluster 65,000-color, 128x160-pixel display measuring 1.75 inches diagonally. The clamshell's screen seemed more washed out than that of other phones, and we weren't impressed with the color scheme on the main menu. As for customization options, you can adjust the backlight timer for the main screen, the keypad, and the external display. You can also adjust the font size, the internal screen's contrast, the sleep-mode timer, the greeting, and the menu style (grid or list view).
Below the internal display is the navigational array, which consists of two soft keys and a five-way toggle that provides shortcuts to messaging, the phone book, the My Content folder (a collection of games, ring tones, screensavers, and applications), the My Favorites folder (a list of shortcuts to frequently used applications), and the main menu. Farther down are the dedicated camera button, a dedicated speakerphone button, a Back button, the Talk and End/power keys, and the keypad. All buttons are well laid out and tactile, as well as easy to press and dial by feel, but we wish the Back button were directly under the toggle instead of the speakerphone key. The keypad has a green backlight when activated.
The Sanyo SCP-3100 comes with a slew of features that belie its simple appearance. The phone book holds only 300 entries, but each can accommodate 7 phone numbers, an e-mail address, a Web address, a personalized ring tone, and a picture. Of course, you'll have to open the phone to see the picture caller ID, since the external monochrome screen can't display images, as we noted earlier. There's also a separate Ready Link contacts list with access to 200 personal contacts and 200 business contacts. There are 10 polyphonic (32-chord) ring tones to choose from, as well as 8 short tones for message or alarm alerts. Organizational features include an alarm clock, a calculator, a stopwatch, a world clock, and a calendar. In addition, you get text, multimedia, and instant messaging; e-mail; 18-second voice memos; voice dialing; a speakerphone; and a WAP 2.0 wireless Web browser. There's also a feature that utilizes GPS technology to detect your location.
