Americans want to talk to each other. Initial stats from wireless providers are showing that coronavirus-related lockdowns are resulting in a huge spike in home voice calling and in Wi-Fi calling on cell phones, as Americans reach out to their friends and family. So far, though, unlike in the UK and Canada, we haven’t seen any major calling-related outages in the US.    The rise in home internet use and voice calling hasn’t come with a similar spike in LTE data traffic, though, as you’d expect. People just aren’t out and about.  Those systems can clog up even if the network as a whole is not overloaded.
