T-mobile not working with ios app but wifi works

Wondering why it won’t work when I use LTE with t-mobile. Looking at diagnosis connectivity test, it shows and as NO but the bottom two values as YES.

Is tmobile blocking this? My friend on AT&T said he has no problems. I’m in the Los Angeles CA area btw.


T-Mobile moved to using IPv6 addressing where available. As a result, in most places, will only connect via it’s IPv6 addresses ( 2606:4700:4700::1111, 2606:4700:4700::1001), and not over IPv4 as well.

This is a good thing. If it shows a connection to either/both IPv6 addresses, it’s working. It’s just not using IPv4.
