Basically the same as the T-Mobile site except they have MMS protocol as WAP 2.0 and I don’t seem to have that setting.
I have not had issues with t-mobile mms, even when i have no cell signal and am on WIFI calling.
What APN settings do you have?

Edit: changed the last statement as MMS protocol is not in my APN settings
