there is no tone option in message setting...but which is in profile setting, there is limited preloaded tones.....in files if i select mp3 it gives options to set as ringtone...but no option to set it as sms tone. I think for sms it don't take mp3 format....if yes, which format if accept for sms?

Also tell me how to schedule turn on/off [ the mobile by giving specific time]
