I get frustrated when my data hasn't been on and then I get the "MMS message cannot be received" notification.

This does not let me know who sent the MMS. On my old phone running KitKat, my Messages app would show un-downloaded MMSs in the sender's conversation so I would know who they were from.

This way, when I'm out of data for the month, I have no idea who to text and request the picture to be sent as an email.

Thanks!
