Deleted text message recovery

If you use messages in iCloud, they were deleted in iCloud the same time you deleted them on your device. Messages in iCloud is a synchronization service, not an archive storage system.

If you don’t use messages in iCloud, then messages are in your iCloud backup, but that gets over-written with each successive backup. It is not an archival backup like Time Machine for MacOS.

I don’t think it go back that far! Also if I remember text messages were on you ISP severs!
