Service is also going live in portions of Boise, Idaho and Panama City, Florida.

As with other ultra-wideband deployments, there are plenty of catches involved if you want a taste of 5G's gigabit-class speed and low lag. In addition to the incomplete coverage and dearth of devices, the very nature of millimeter wave access makes it finicky. It rarely ventures far indoors, and it doesn't take much interference to lose the connection and drop to LTE. You'll most likely be using 5G on the sidewalk rather than inside the coffee shop. It could take a long while before you can simply assume coverage is available, and it might only reach deep indoors as the technology spreads to lower frequencies.
