Default At&t APN to use data for MMS only?

Hey all,

Is there a way to setup my phone to use the at&t data for sending and receiving MMS only? I have a hotspot that I carry around so I don't need the data on the phone for anything else. I tried setting APN type to MMS only. But still getting hangout messages that aren't text related when WiFi off and only phone data .
