Band n25 SA on Galaxy S22 Ultra still not enabled

T-Mobile has recently spoken about the newer n25 SA band being used lately, and it was even tested with my model, the S22 Ultra. Lots of people are already picking up this band (with other model phones, or are having to hack their S22 to even enable the n25 SA band) in carrier aggregation with n41 for improving 5G UC speeds. I have a TMob carrier firmware S22U device and in the most 2 recent software updates, Nov, and now just got Dec ver. S908USQU2BVL1. It's unbelievable that TMob has still not enabled n25 SA. Only n25 NSA is enabled (since Nov update) which is useless. Only the new n25 band can CA (carrier aggregate) with n41 on SA, not NSA. This is very disingenuous for T-Mobile to be out touting this update while not offering it on a phone that has all these bands by default but is not being enabled by T-Mobile, especially on such a flagship phone like the S22 Ultra. What is going on?
