Google Project Fi's wireless phone network is getting stronger. An update to the Google Fi app for Android now includes support for US Cellular, a regional carrier with coverage predominantly in the Midwest.
US Cellular is a brand-new partner for Fi, which Google calls a "network of networks" to connect its users to the strongest network around, be it 4G LTE or Wi-Fi. If you hop into range of a stronger signal, Fi will automatically switch you over.
Project Fi already grabs LTE signal from T-Mobile and Sprint, so the addition of US Cellular's resources expands Fi's reservoir of signal for local and roaming users. Now if only Google would expand Project Fi beyond a few compatible Nexus phones. Read CNET's adventures with Project Fi here.
