H E L P: MMS APN settings, Lumia 640--Mint Mobile???

[Davein757]

I'm so frustrated dealing with this I'm ready to just never have a cell phone again.
Microsoft Lumia 640. Mint Mobile. Windows 10 Mobile.

Everything works EXCEPT pictures in text. I've tried a dozen different ways to set up the APN and nothing works. I *thought* I had it figured out using fast.t-mobile.com, but 99% of the time, I get the stupid "Can't send" message.
Any screaming you've heard from the distance was me...most likely.

What is the setting for this dumb APN thing for MMS?

That link was completely USELESS. I have a WINDOWS phone, not apple or android.
