Deleted all messages but they are still taking up space on iPhone? Why do deleted messages still take up storage space on iPhone?

But they're still on the phone. Backuptrans iPod/iPhone/iPad Space Free Up provides a good solution for you to delete messages from iPhone permanently and free up these storage space.
