How can I retrieve lost iMessage??
how can I retrieve lost messages??
Look in Settings, [your name], iCloud.
If “Messages” was turned ON in Settings, [your name], iCloud then no you cannot retrieve them.
If “Messages” was turned OFF in Settings, [your name], iCloud then you can restore the entire most recent backup and lose everything else since that date. Without a daily iCloud backup that is probably not feasible.
