I am using Samsung Galaxy Ace GT-S5830. I can't add new account in my gmail. When I'm trying to add, it will ask me if I'l create a new account or I will be adding an existing account, If I move forward, the screen will display "Your phone needs to communicate with Google servers to set up your account. This may take up to five minutes", after a few minutes of waiting, the response will be, "Can't establish a reliable data connection to the server. This could be a temporary problem or your phone may not be provisioned for data services. If it continues, call Customer Care". This continued even after a few times of trying and even I have a strong wi-fi connection.
