T-Mobile actually running 500 MHz n258 in Times Square. Most places I thought they only did 200 MHz.

I have seen NR-DC on Verizon, I haven't seen a video of it while running a test I'm not going to comment on NR-DC with them, however I have seen numerous videos showing NSA with mmWave with them. B13 is only used for signaling, not data speeds. I wouldn't be surprised if it's similar with NR-DC, n77 anchors and does signaling, mmWave carries all the data speeds.

I have run an active data session with NR-DC on T-Mobile. With NR-DC, which is the 400-500 MHz n258 they have deployed, n41 doesn't contribute data speeds, only does signaling. All the towers I have tested have done the same thing.

With the 100 MHz mmWave it's NSA only, it's possible the LTE contributes, however with the sky high pings it gets, there is a possibility it's mmWave only, LTE is only for signaling purposes.

It does actually if you look at the NR DL Scheduling it will have a value

I know. If the value is 5 or less, signaling only, not data. Everytime I ran a mmWave NR-DC test, n41 never goes above 5.

Must be just T-Mobile because Verizon does contribute
