The one plus 3t has 4g connectivity so it IS supported and will be supported on the network for many years to come. I see no reason for a phone not to be supported on the network unless it is deemed dangerous for use (For example, the Note 7 will be blacklisted soon, unless it hasn't been done already).

It will work.
Volte will work, but not voWifi.
EE still insist on having their draconion fw installed for this to be enabled.
