Description
The Sony Ericsson W580i is a quad band GSM world phone that works anywhere in the world where GSM service is available and can operate on 850/900/1800/1900 MHz bands. In the US, AT&T is the only carrier that offers it. Unlike the many 3G GSM phones in AT&T's portfolio, the W580i has only EDGE for data. The phone's reception is very good in the Dallas area where AT&T has strong coverage. The Sony Ericsson usually gets full bars and loses 1-2 bars when inside of a large building. We have never experienced any drop calls or lost of signal. The Sony Ericsson W580i has outstanding voice quality for a GSM-only phone (some 3G phones with their superior voice codec, like the Sony Ericsson K850i do sound even better). The voice is not only clear and full but also loud. If you are looking for a near-landline voice experience, consider the W580i or the higher end K850i as they both have pristine voice quality.
