Archived text messages can be viewed on Android phones using the message backup app used to create the archive. SMS Backup +, G Cloud Backup and SMS Backup and Restore are popular apps with this functionality.
Third-party apps are required to archive and retrieve messages. Android's built-in text messaging app does not include a function to archive messages for future retrieval. To retrieve a deleted message from Android's stock text messaging app, use third-party software such as Android Data Recovery immediately. These deleted messages are only recoverable for a short time.
Using text message retrieval software on another person's phone without consent is a violation of federal law. Always obtain permission before reading another person's electronic communications.
