I get 5G mmWave in my home and around my neighborhood in Seattle. In fact sometimes at home I’ll turn off WiFi on my phone just because I’m sitting in a WiFi dead zone but the mmWave still works great.

This is on Mint Mobile, a budget MVNO now owned by T-Mobile. I pay $20/month for 15GB data.

is anyone deploying mmwave outside of maybe sports stadiums?

I have it in my home, but I live in the center of a major city. It just speedtested at 476.64 Mbps down, though I think I've seen 650+ in the past, but I might be mis-remembering that.

However, I only get 5G mmwave (indicated as "5GuW" on the phone) on my work phone.

The carrier I use for my personal phone charges an extra $20/month for 5G, and I don't care that much, so I leave it at 4G LTE.

Edit: Just re-tested and got 767 Mbps.
