+Wi-Fi Music Store over a cellular data network.+

The iPhone uses only one internet connection at the time and if there is an available wi-fi network that you have access to and wi-fi is on, your iPhone will connect to the available wi-fi network first. Leave the range of an available wi-fi network, your iPhone will switch to the cellular network and vice-versa. This process is automatic and seamless as long as you have wi-fi access on. There is no setting for this.
Once exception if visual voicemail is available with your provider. Visual voicemail messages are downloaded to the iPhone via the cellular network only even when connected to an available wi-fi network.
