Can you still find short messages from two or three years ago in the server?

Short messages from a few years ago are basically difficult to retrieve, even with the current technology, because after the mobile phone deletes the short message data, the mobile phone data will continue to be overwritten by itself, so that the deleted short message cannot be recovered at all. Therefore, if there are some very important short messages on the mobile phone, it is recommended to make a backup in advance. The mobile phone has the function of cloud backup, just turn on the corresponding short message cloud backup function.
