The move follows a government circular in 2008 to promote telecom reform, and allow subscribers to freely switch networks to boost competition in favor of minor players.
The program allows mobile users to shift from one operator to another without changing numbers.
携号转网允许手机用户在不改变手机号码的情况下转换通信网络。
文中的freely switch networks和shift from one operator to another without changing numbers都是指的“携号转网”,也就是换通信网络不换手机号码。此举将打破国内电信巨头的market dominance(市场支配地位),使其面临customer drain(客户流失),而同时增加了其它wireless operator(无线运营商)的market share(市场份额)。目前该计划正处于trial phase(试点阶段)。
除了网络之间的“转换”外,我们平时工作中的“调班”就可以用switch表示。例如:Have you been able to switch your shift with anyone?(你找着能跟你调班的人了吗?)如今快节奏的生活使人们在看电视的时候也频繁switch channels(换台)。商家有时采用以廉价商品招徕,诱使顾客上门后再兜售较高价商品的“诱售法”,就是bait-and-switch。
