My "Samsung sgh i607, doesn't have dialing sound"

do you want Network unlock code for your Samsung BlackJack II phone?If so, then you can get it from Unlock-Zone.com here you need to specify your country,Network name to which it is locked,IMEI number of your phone.

ahmm.try to go on the setting then look for audio or sounds settings..
if nothing happen,unit must be hard reset.

Are you using a bluetooth? This will prevent the earpiece from being used but will allow the speakerphone to function properly.

reset code *2767*3855# let it reboot factory settings

I have a solution. Call at&t. they will send you a new one. I have had my phone for 5 months and it happened to me also. There's a warranty on the phone itself that covers it from the day "you" started using it. I bought mine from a friend. Cool!! It should be here in 5 days free shipping.
