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?
Although, Currently my Redmi Note 7 is still working on LTE AND is still able to make/receive phone calls. Although I'm still not willing to swap the SIM cards into another phone until I know it's gonna work properly.
Went to the store, bought a new SIM installed it. No dice. Rep there had no clue as to why it wasn't working. "I've never seen anything like this before."
T-Mobile chat is sending a tech to my house this afternoon to service my phone. Updates as they come.
Yeah. THey never showed. No straight answer from the chat ppl. UGH.

Tmobile doesn't offer tech support for phones they don't sell.
My Xperia 1 III had been working fine since I ported from AT&T to T-Mobile in Feb 2024. Although only one 5G band is available, I've never had any issues with VoLTE or VoNR not working. 4 days ago, on June 7, the phone stopped connecting to the network. I spent hours on the phone with support and another two hours in the store. A new sim did not work either. I've had to use my old Pixel phone as a replacement for now. When I open the diagnostic screen, I watch the phone bounce to every available technology it can find (GSM, LTE, etc.) but it fails to connect. T-Mobile must have pushed a change on their network a few days ago. I am still waiting to hear back on the status of my trouble ticket.
Networks do change. With upgrades to the network and areas changing. Sometimes a band that was deployed in an area is no longer the best option for that coverage and it is changed once the towers are upgraded. Blacksburg, VA was a good example. Most of it was band 2 and band 4 a decade ago. Now it's mostly band 71 with 41 in certain areas.
Holy crap. It worked!!!! WOW, dude, where have you been all my life!!!
Seriously. This needs to be shouted from the tallest mountain!!!!
