5G is coming, and with it a massive boost in bandwidth that will feed artificial intelligence applications, enable the long-fabled internet of things, and deliver more streaming video. Lots of streaming video. But all that extra bandwidth won't be much use if the average consumer can't afford a 5G connection, or if those connections are hobbled by restrictive bandwidth caps.

When the major carriers rolled out 4G in the early 2010s, it typically wasn't offered as a separate service from their existing 3G networks. 4G speeds were used as a selling point where they were available, but they didn't cost consumers directly. That might not be the case with 5G.
