更好的实用性通过Wi-Fi打电话的智能手机

当没有Wi-Fi或者信号太差的时候，Republic的手机就会切换到运营商Sprint的手机网络进行通话和短信。而手机网络的通话与短信也不会额外收费。如果你在Wi-Fi网络下拨打电话，而通话过程中离开Wi-Fi覆盖范围，那么通话就会切换到手机网络。

Most other smartphones can make Wi-Fi calls, but these typically require an app. Republic modifies the phone's main dialer and texting functions to work over Wi-Fi whenever possible. You don't have to do anything special to initiate a Wi-Fi call or text.

虽然多数其他智能手机都可以通过Wi-Fi打电话，但它们通常需要安装应用。Repubilc对Moto X的电话和短信功能进行了改装，只要有Wi-Fi就启动使用。你不需要任何特殊设置就可以通过Wi-Fi打电话或发短信。

Republic has been in business about a year, but its first offering had several drawbacks. First, it worked only with a clunky, limited phone, the Motorola Defy XT, which had skimpy memory, a small, low-res screen and only the older 3G cellular data network. Second, call quality over Wi-Fi was iffy, with audible echoes and some clipped words. Third, the handover between Wi-Fi and cellular was clumsy. The phone had to hang up the Wi-Fi call and redial over cellular.

Republic已经运营了约一年时间，但其首项业务存在几大缺陷。首先，他们当时服务只有一款笨重机型摩托罗拉Defy XT，这款手机存储空间不足，屏幕又小，分辨率低，而且只支持较老的3G手机网络。其次，通过Wi-fi打电话并不稳定，经常有杂音和中断。再次，Wi-fi与手机网络之间切换也有问题。这款手机必须先挂断Wi-Fi通话，然后用手机网络重拨。
