I don't keep data on all the time stop if u receive an MMS text, all I get is a very very short sound alerting me the MMS text has arrived and I need to turn on data. Consequently, I miss these MMS texts because I don't hear the very very short sound unless my phone is out in the open and it's totally quiet in the room.

Would it please be possible to have the specific contact's configured notification sound play? If not the configured setting, what about the default text notification sounds or some other much longer sound?

Thank you very much.
