Dopod D600 SMS ringtone

I also use D600. What you said (SMS voice may be deleted once) is impossible. The SMS sound that comes with the machine cannot be deleted. If you can't find it, you can hard start it once, that is, restore the factory settings, and then the SMS sound that comes with the system will automatically recover.

The reason why you can't use the downloaded SMS prompt tone is because you put it in the wrong folder. The downloaded SMS prompt tone should be placed in the windows root directory of the main memory of the machine, and then it can be set in (Sound and Reminder), but the format of SMS prompt tone must be correct. You can log in to dopod Club, where there are many SMS alerts.
