keeping 3g connection always active on android ics tablet
I have an android ics tablet and i can connect to a 3g network using a 3g dongle. Also I can connect to wifi. But whereas in settings there is an option to keep wifi active even when the device sleeps, there is no such option for keeping 3g connection active while the device sleeps. I would like to somehow keep the 3g connection always active as I don't have a strong wifi connection where I live.
Can anybody help me with this?
Thanks in advance.
