Hi,
If you have an iPhone and have iOS 9.3 beta2 you receive carrier update 23.5.4 which makes your LTE IPv6-only. There are major issues with TMobile's existing NAT64 implementation. I suspect it is limited to UDP traffic, but I am limited from what I can test with my iPhone. Most TCP traffic seems to work, but it's impossible to do Facetime (audio or video) calls, etc. The push messages (TCP) are received by both ends, but the session never successfully connects and it times out.
Alternatively I've noticed it's impossible to connect to any Plex servers (TCP, port 32400).
All of this is resolved if you use a VPN, which is frustrating. I hope this is fixed before 9.3 rolls out to everyone.

This is not an outage. You are using beta software and it appears to never have worked. Nonetheless, please unicast email me, cameron.byrne at t-mobile .com. I am interested.
