I still remember when I lost all my sms messages from the inbox because of multiple tasking. I know it’s weird, I had to change the cell phone for the good.. Yes, I was never able to retrieve those deleted sms messages as I never made a back up of messages.
Fortunately, here is an SIS file (an standard format for most of the mobile phones) softwares that can back up sms messages into an text file for free. With this freeware sis file message backup software you can instantly save all sms messages in text file for future use.
The software named Message mirror works on Nokia and other phones that supports .sis format (including Symbian OS 9.0). You can also hide messages and backup all messages in Text, Html, Csv and XML format.
There is also a paid full version of Message mirror, but the free version would suffice your needs.
