I got the unlocked version from the google store to use on Mint (T Mobile mvno). It does not connect to UC which I figured it wouldn't considering only the Verizon variant has mmWave. However, I went to the T Mobile store and tested their 6a variant and it did connect to mmWave UC, speed test over 500mbs. So I'm curious if loading the T Mobile rom on an unlocked phone would support it.

Ok, I see T-Mobile also refers to their n41 (2.5GHz) 5G as Ultra Capacity
Yep. That's exactly what it is!

I have the 6a bought from a T-Mobile store (well, mailed from T-Mobile as they didn't have sage in stock). I see 5GUC in some places in Ann Arbor, but don't see DL speeds over about 150....

Out in the wild, I never see over 150 either. However, in the T-Mobile store, I get UC and over 400. I have a theory they have one of those personal cell things in the store. I'm in the Cleveland area. I turn off 5G for the most part, it keeps the phone cooler and helps with battery life.

I'm betting that the 5G UC symbol is for native T-Mobile, not MVNOs. If you see Mint Mobile in your indicator, it just says "5G".

I believe only Verizon shows "Verizon" even if a MVNO is used. Most carriers show the MVNO name if one is used, and avoid the branded indicators.

You are right. Even though the band is the same, only the T-Mobile sim displays UC. Found a good video explaining the differences.

I have 2 questions related to T-Mobile and Google purchased phone. I am on T-Mobile and have the default build.
1. Is there anything to be gained or loss by flashing the newer T-Mobile B1 build vs default B1 build?
2. Does flashing to T-Mobile B1 build exclude me from the Android 13 Beta program?
