Does T-Mobile support Doogee V30 Pro phones?

Final update: I got the phone, and everything worked fine EXCEPT:

1. The flavor of eSIM card that this phone has doesn't work with T-Mobile. 

2. About 50% of my text messages couldn't be set. I tried looking through every setting; RCS vs SMS didn't help. About 10% of THOSE messages could be sent if I tried again later; some never could. THAT'S NO GOOD!

So I got online with Tech Support again. I had other issues as well; I was bringing another phone line onto my account. Spoke with three people; a manager (#2) flat out lied to my face and told me the incoming phone had been declared lost (which the previous carrier and support person #3 declared false). He also ridiculously claimed "every ad" selling a phone online mentioned the IMEI of the phone (which is unique to each phone in the world), then shifted to say only 3rd-party sellers did this, then shifted to blame "non-US cellphone makers" for all my problems.

All three told me there was no way to determine if a phone would work with T-Mobile without the IMEI number. They tried to claim it was because they needed to see if it was unlocked, but that's something guaranteed in the purchase of most phones. 

#3 finally convinced me the problem was the phone only has 4g capability on T-Mobile's bands (which is still wrong; 4g certainly supports text messaging).

T-Mobile's phone support, and even their Tech Support, are really just Indian-national contractors reading off of scripts; they don't actually understand the technical implications of the words they are told to say.

TL;DR: Doogee V30T does NOT fully work on T-Mobile networks. And T-Mobile's phone support sucks.
