You need to have those messages synced to Ovi Suite, then export them in an xml format. However I am not sure if the format Ovi exports to is compatible with Android. Android does have an app that imports xml to sms but the formatting inside the file may be different.
The only way I know off to directly restore from a Nokia is on a Samsung device, since Samsung's Kies software has the ability to restore from a Nokia and iPhone backup.
