Hey @marci71, I hope you're doing great.
If you use the stock Samsung Messages app, you should by default have the trash option enabled. To view deleted messages, within the Samsung Messages app, press the menu button>Trash
From there, you can select messages and then there will be a restore option. Just note, messages that have been in the deleted box will permanently wipe out after sitting there for 30 days.
If you use another Messaging app, recovery options may be limited if not backed up prior to deletion.
Hope this helps!
