How can I find deleted messages and mail
Question marked as
Mail: there will be a Trash mailbox that holds deleted emails for 30 days, or until you open Trash and manually delete them.
There is no “trash” folder for messages. Go to Settings/[your name]/iCloud. Is the switch for messages ON? If it is there is no way to recover deleted messages.
If it is OFF and you have a backup that was made before the messages were deleted you can restore that backup. Doing so will overwrite everything on your phone, not just those specific messages.
You can also try asking the recipient to copy the message and send it back to you.
