Samsung S20 TMobile version or UNLOCKED version? Pros and Cons...

[mogelijk]

You should have it supported on both the US unlocked and T-Mobile versions of the S20 according to this: https://www.techwalls.com/samsung-galaxy-s20-model-number-sm-g980-g981-differences/

I understand it will have the needed frequencies; just wanting to be sure that T-Mobile won't be weird about giving 5G access to a non-T-Mobile phone.
