I have a Samsung Galaxy Gio and the 3G network has suddenly stopped. It was working a few days ago and usually when I turn the wifi off, the 3G comes up automatically. But the wifi got turned off suddenly and the 3G hasnt come up since. When the wifi is turned off, there is 4 little bars next to my battery that i think is the signal where the 3g would have been in its place. How do you get the 3g up and running again? im desperate and I have restarted and turned of and on my phone again and turned the packet data on and stuff. Suggestions please people im going away on holiday soon and there will be no wifi connection so I want my network running!
