How to recover deleted txt messages on iPhone 22

Unless you house your messages in iCloud, they are stored on your iPhone backup. Restore that backup to retrieve the messages that were present when the backup was created.

Apple never released a product called iPhone 22.

Backups are stored in either iCloud or on your computer. When erasing the iPhone, you can set it up from that backup.

If you didn't have a backup, you can't restore from one.

...and you would have to restore from a full backup- you can't just migrate the texts.

The only way you can recover deleted text messages is if they were included in a recent back-up.

And no more backups have occurred since the time that the messages were deleted.
