If it is leaving your phone then the issue is with AT&T / the phone you are sending to. Get some one to confirm the AT&T MMS settings with customer services. It's the network, not the phones

Unfortunately not all the carriers have opened their system to each other to implement cross carrier MMS.I can't remember specifically which carriers have opened up to each other. Though I thought that Tmobile and att were open to each other. Make sure that the video is 10 seconds or less as there is a size cap for att.

Try adding these settings:

MMS Proxy: 216.155.165.50:8080
MMS Max Message Size: 1048576
MMS UA Prof URL: https://www.apple.com/mms/uaprof.rdf#mn_p

I'm also with T-mobile and was having problems until I added these settings. Hope it works for you as well.

No idea. But maybe
1.) Contact them.
2.) Apply a fix above.
