Short codes working for anyone?

It loads forever until a restart and can't do anything

I tried a few T-Mobile short codes. No glitches on my S23.

Same pop-up as on your image appears (USSD code running...) then gone in about 1 second with my requested S.C. action displaying right after.

Same with me. I'm using the S23 ultra. I use it to check my hot spot use. I'm also T-mobile

Working for me also and no problems.
