We tested 5G across America. It’s crazy fast—and a hot mess

Joanna Stern traveled to 4 US cities that have started rolling out 5G access, sharing her experience. Obviously, this will change over time as more 5G hardware is built out and the 5G network expands, block by block.

I suspect 5G coverage will be a lot broader and the temperamental nature of the mobile 5G experience a lot more stable and less heat-sensitive by the time Apple rolls out their first 5G devices.
