I am on T-Mobile and when I roam, my phone will connect to the network for phone calls and SMS, but will not connect to the data services. I have it turned on for data roaming in the settings. My wife's 6P is also on T-Mobile and connects to data just fine. Any ideas?

Mine did the same, went into mobile network settings, network operators, search networks and then choose automatically. Also make sure data roaming is on.
The phone then started working for roaming, in one country I had to do this twice before it picked it up

Change the APN Protocol (not for roaming protocol) to IPV4/V6.

You could also go into the testing menu (dial *#*#4636#*#* - phone information) to global auto but I think that setting gets reset every now and then.

Was working on my first trip overseas two mons ago. Same location as before but now i

I am am also on T-Mobile. On my first trip to Nicaragua two months ago my pixel work fine. Now my phone will connect to the network for phone calls and SMS, but will not connect to the data services. I have it turned on for data roaming in the settings. My wife's S5 is also on T-Mobile and connects to data just fine. T-MOBILE reset me several times. I will get a message then from Claro or Movistar saying no data because your data roming is off. No matter if I have it switched to on or off after resting I will get the message everytime.

I was having this same issue in Thailand and not Japan. Changing to ipv4/v6 didn't help but explicitly changing to 3g preferred instead of LTE preferred fixed it for me

Posting this to add the list of things that may work..
I have a Pixel 2 and was having this same issue with a Twilio sim card (runs on T-Mobile) while in Australia, New Zealand, and later in Ireland (home network is USA). I had tried all kinds of random APN tweeks mentioned in this thread (https://forum.xda-developers.com/tmobile-lg-g3/help/international-data-roaming-to-t2823789) with no success. I had also contacted google and they sent me a whole new pixel 2 but that made no difference. After much googling heres what I found:

Edit the APN settings and click the APN Type. Add "default" to the beginning of that list. Try and save, it will tell you that you can't set the type to default, that's fine. Press the home button and re-navigate to the mobile settings and default should be successfully saved in the APN type. That alone resolved the data connection issues for me but I was only getting H internet rather than LTE. I then also changed the MVNO setting to `SPN` and suddenly got LTE connectivity.
