Add additional options to carrier limits under MMS. For example, Verizon allows 1.2MB for photos and 3.5MB for videos with a possible 300-600kb additional, likewise they offer over 100MB limits over wi-fi with their messaging app. The limit options currently listed in this app are insufficient. The highest options are 2MB or No Limit. I think the options should be expanded, or better yet figure out carrier limits and make the specific carrier limits available as options.
