I have 4 phones on a family plan, for over a year now. Just today, none of the phones can send MMS texts. A return message from "#" will say "Message not found". I sent an MMS to someone from another carrier -- same thing. That person then sent me an MMS, and I received it as normal.
SMS works both ways, MMS can be received, but can't sent MMS. Checking our data usage from the app shows only my phone at 2.8GB usage with the rest <1GB, and we have "unlimited" on each line.
Anyone else having an issue with MMS today?
