Samsung Galaxy S switches between edge and 3g network.

[Power Crippler]

I am using Samsung Galaxy S and my network switches between 3g and edge. When I am using the internet sometimes it works fast and sometimes slow. I came to know that the network is switched. How is this possible and can anyone provide me information?

When you are in 3g network it means that you are on a high speed network and the browsing on the net will be fast. When you see the E symbol in your phone it means that the 3g network is not available and your phone is access the edge network is available for browsing which is not fast as 3g network The network depends on the location you are. In many locations you can’t even get the edge network properly. Sometimes it happens that you are walking around the network automatically switches between edge and 3g. This happens due to the network connectivity within the location. It is possible that the service provider may have not given the 3g network to some places.
