How can I make Android connect to an open Wi-Fi network even when using Cellular data?

    mate, this feature is either or, and both cannot be enabled that way. since most phones are designed to use only one connection for data services, it is built that way. may be you can contact the ODMs such as foxconn to have them design a custom handset for you (sic) :P
    Battery usage on smart phones, is the reason why i think that this is not possible.

      You mean without the app , by default both wifi and mobile data would be used when both are enabled and available?

      With both wifi and mobile data on - When wifi is accessed I have noted the 'H" symbol of 3G mobile data access automatically de-activating......what would this mean? toggling from 3G to wifi?

      So app not necessary?

    In settings>Wifi you should have an option to set it to notify you if a wifi connection is present. And to give you the option to log into it or use your own data plan.

      Is this setting in Android 4.0 and greater?

      I misspoke. On my phone (4.0.2) you swipe the notifications and it will say: Wi-fi networks are available" Go there are you should be able to pick the network you want. If it is not there, and you know you are close, the network might not be broadcasting the SSID. If that is the case, then go to settings and connect there. You will have to do it manually.

    What connection does Android use when both WiFi and mobile data are simultaneously enabled?

      You mean that when both wifi and mobile data connection are enabled and available then only one connection is used and that too wifi?

      Yes or No?

      and Is there a custom setting for this as mentioned by Chris below!?

      Yes, i think wifi will take over but mobile data will still be there if higher demanding process or messaging, call needed
      as example for internet Wi-Fi Direct uses a local IP and will not conflict with 3g connectivity.

      considering custom settings, perhaps you hav an option like Prompt me when a saved hotspot is found nearby, in Wifi Network Settings...

      you can make some rules like
      WIFI Connected, Turn Off Packet Data
      WIFI Disconnected, Enable Packet Data
