Basic features include text and multimedia messaging, a vibrate mode, a speakerphone, instant messaging, a mobile MediaNet Web browser, an alarm clock, a calendar, a calculator, a tip calculator, a unit converter, a timer, a stopwatch, and a world clock.
If you want to download more graphics and ringtones for personalizing the phone, you can do so via the phone's AppCenter, which directs you to the AT&T's MediaNet homepage. There aren't any games for the phone, however.
We tested the Samsung a107 (GSM 850/1,900) in San Francisco using AT&T Wireless. Call quality was pretty good. On our end, we heard our callers just fine, though we detected a tiny bit of static and the voice quality was noticeably hollow.
Callers also reported good call quality. They said we sounded a bit tinny, but it wasn't a big deal. However, they said that sometimes the ends of our sentences would drop off a bit, and they, too, reported a few static issues. Speakerphone quality was mediocre at best; our callers sounded harsh and there was a lot of echo and hiss on their end.
The Samsung a107 has a rated battery life of 3 hours talk time and 10 days standby time. It has a rather poor tested talk time of 2 hours and 43 minutes. According to the FCC, it has a digital SAR of 0.3 watts per kilogram.
