It means you do not have 3G coverage in that area.

Restore the phone, if you still have the problem contact Vodafone.

Try this really quick and lemme know if something changes. Go to settings, carrier, then turn off automatic. When a list of carriers is shown, choose one that isn't yours. When you get "no service", switch back to the carrier you were using. This exact situation happened to me when I upgraded to 6.1, and this is a temp solution. Many people are having this issue, and it seems it is a bug in 6.1

I am also using 3G services and when network coverage is full then it shows 3G on the top of mobile screen and if not then it turned into E. It all happens because of Signal.

yeah you are right but mine never show 3G even network strength is full.. its like some another problem..
i am paying for 3G service and even i don't get 3G..so irritating brov..
