Apple iPhone Troubleshooting Tip – “Could not activate cellular data network”

Last week when I updated my Apple iPhone 3G with the new firmware updated version 2.0.2 released recently. As usual the iPhone worked perfectly normal after this upgrade, but surprisingly today morning when I tried to check my mails on the phone it started giving following error “Could not activate cellular data network” which I expected to be related to service provider and blamed them but later something else actually happened. I tried restarting the iPhone for several times but it didn’t work at all for a long time after a series of attempts.

I really got fed up and I tried calling AirTel customer care, but they suggested me to call Apple Care India(1800-425-0744) which is toll free and I expected some good support from them. When I called Apple Care people for help, they guided me to the following URL to have a look at support information on iPhone: http://www.apple.com/support/iphone/in/. So again with a hope to fix it I tried opening the web page but the above link disappointed me by giving “Page Not Found” error( Apple are you Listening? sorry Reading?).

None of the above information or support helped me to resolve this issue, then I came back to home and started searching for this problem on Google(Yes I believe in Google) expecting some useful information. Fortunately I found some useful information which gave me some relief after all the attempts.

I had resolved this issue very easily by following these steps(twice):

Go to: Menu > Settings > General > Reset > Reset Network Settings. Once you Reset the network settings, iPhone3G got restarted and then above issue got resolved related to cellular network and now it was working fine. Thank God(Should I say Thank you Google?).
