Will SMS be accidentally deleted after encryption?

Yes, because SMS encryption is only to prevent your important SMS information from being leaked or your privacy from being peeped into. However, accidental deletion will still happen. Encrypted and locked information is secure, not locked information files. Misdeletion occurs when it is deleted by mistake, or when the phone is damaged and cannot be retrieved. If the suggested information is important, you can back up the information content. Now there are many mobile assistants who can back up address books and information.
