We have a Nexus 5X which we ported from Project Fi to take advantage of the 55+ plan before the price increase. To get the phone to work with T-Mobile I had to do a network reset but even though it works, the Call Forwarding menu is still missing from the Settings. To see if I could get the menu back I did a complete reset on the phone but the Call Forward menu is still AWOL. (n.b. Project Fi does not use GSM call forwarding and substitutes as forwarding menu in the Fi app.)
Today I contacted Google Support to find out if there was a way to get the menu back. Their CSR told me that the Call Forward menu was under the control of the carrier and that I needed to contact T-Mobile about it. My reply was that he needed to tell me exactly what I needed to say to T-Mobile because otherwise they'd just say, "Nexus 5X is a BYOD, Good luck with that." At this point he promised to research the issue and call me back.
Now, I do understand that there is some carrier package that gets downloaded and installed on newer Android phones and what I suspect is that T-Mobile's package has not been loaded. (I'd prefer to believe that T-Mobile would not be so evil and customer hostile as to intentionally disable the call forwarding menu.) I suspect that this package has not been installed on this phone. What I need to know is if there is any way to get the T-Mobile settings package to reinstall on our phone?

I feel like a total idiot. The Call Forwarding menu isn't in the Settings menu. It's in the menu for the phone dialing app.
