Does any os support mms?

So I found this website, and it has a lot of info about MMS:

https://www.nowsms.com/doc
https://www.nowsms.com/doc/mmsc-messagin...-mms-works

It seems that primary communication between the phone and operator is a protocol called "mm1", and communicates with an MMSC server.

Additional Information can be found here:

I can't find too much about the WAP protocol right now.

However, to create MMS files:

and to send:

It looks like you need to send an SMS to let the other phone know to get it:

T-Mobile's protocol is here:

MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy: <Not set>
MMS port: <Not set>
MMS protocol: WAP 2.0

I hope this gives some place to start to working on MMS.
