Can Nokia 5700 SMS be retrieved after deletion?

It is really impossible to recover after deletion, but now you can introduce a software called "QQ Synchronization Assistant" installed on your mobile phone. This software can back up important business cards and short messages in your mobile phone, and support backup in memory card and network at the same time. When you think there are too many good things in your mobile phone and it is a pity to delete them, you can back them up first and then delete them in your mobile phone. Moreover, they are also very safe on the Internet, and can only be viewed with your QQ password.
