Is my Android asian phone blacklisted?


Hello! I have a Xiaomi (K40 gaming) phone, I've been with TMobile since 2 weeks ago without any issue, I've just inserted the SIM in my cellphone and everything went smoothly.


Today in the morninrg I've noticed that I had no internet connection, the signal bars were there but no 5G nor VoLTE icon appeared. Plus, I was not able to make any phone call and SMS were not sent either. After a couple of hours, I was able to make and receive calls and SMS, but the Internet is still missing.


I went to a T-Mobile store and one guy there "explained" me that Chinese phones are not meant to work in US networks, that somehow the network it's struggling to connect to the cellphone band and because of the "US situation with China" these phones usually have these connection issues and that at some point, these phones will be blacklisted. Since my phone worked just fine the last 2 weeks, I don't think these arguments are valid at all.


On the other hand, I called to customer service and they've raised a report for the technical team to investigate.


Is this blacklisting a real thing? Any clue on why T-Mobile restricted my service?

This community is awesome, 
Followed the steps above and entered in *#*#86583#*#* it stated that it was disabling checking and now I have the white VoLTE symbol on my Xiaomi Redmi Note 11 5G.  (the site link is in German but it still works) Will update if anything changes
