I utilize Tune-In on IOS to listen to radio stations from around the world. Lately some stations are being blocked on the T-Mobile. It is not the radio station since I am able to listen from home internet connection or VPN to my home and listen to it that way. Just wondering if T-Mobile is filtering these sites and if possible how to send a request to modify the filtering to allow these stations/ip addresses.

They do not from my understanding. It may just be a DNS issue or even an IPv6 issue. The iPhone on cellular networks all run IPv6. Try an Android device using the app and see if you can. If you can't switch the APN to IPv4 and see if the problem goes away. If it does then these sites you are trying to connect to are the ones that may need an "update"
