中国联通的世界风业务最早于2004年推出,当时LG W800、三星W109、摩托罗拉A860等机型让我们第一次见识了双模这个新鲜概念。不过双模手机主要是针对商务用户,普通用户需求不大,因此产品更新速度相对来说非常缓慢。一段时间内,除了三星推出过几款双模手机之外,国内几乎只有酷派表现得十分活跃。KW820是LG推出的第二款双模手机,和大多数双模手机不同的是,支持双呼叫,而且还有GPRS功能。

For a period of time, in addition to Samsung launched several dual-mode phones, the domestic almost only cool performance was very active. The KW820 is LG’s second dual-mode phone, unlike most dual-mode handsets, which support dual calling and have GPRS capabilities.
