While we don’t know exactly when and how quickly the fifth generation of smartphone technology, or 5G, may spread beyond a handful of large cities, there’s no debate about this: 5G is coming. All four major U.S. mobile operators now offer 5G service in select locations, and, as the infrastructure evolves, those services are set to expand. What’s more, mobile industry experts expect that once the 5G floodgates open, consumers will be highly motivated to trade in their 4G devices for ones able to take advantage of 5G networks and services.
