I have an iPhone and obviously I always use iMessage with friends that have an iPhone. I want my SMS to be sent also if iMessage is not available, so I switched on "Send as SMS" option.

Today I sent an image to a friend and iMessage was no available. If spending for a SMS in ok, I want to send images only when iMessage is available. Is there any option that can enable SMS and disable MMS when iMessage is over?


The MMS switch only disables MMS, not iMessages with picture attachments. So you can turn the MMS switch off to get the behaviour you desire.
