How to recover messages deleted twice

What do you mean by “deleted twice”?

If you deleted them, then deleted them from the deleted messages folder, they are gone for good. There is no recovering them.

Let's start with recovering one time before we worry about trying for two. If things work the first time, you won't need the second.

The link to the document above your name has all the answers.

1) You must have iOS 16 or higher installed on your phone

2) You must have deleted the message.....after.....you installed iOS 16

3) It must be less than 30-35 days since you deleted the message

If all 3 conditions above are not met, it won't be possible to recover the message

Under Messages / Edit, the Recently Deleted folder will not even appear unless you have messages that meet all of the 3 requirements above.
