Switch from 2G to 3G mode

[grganki]

hi
I am not able to find any option for switching from 2G mode to 3G mode and vice versa.. It gives only one option "Use Packet Data" I am not sure if this is the 2G mode or 3G mode. Can anyone please help on this.

Settings > wireless and networks > mobile networks > network mode.
Select GSM for your 2G network or WCDMA for 3G.

I have a Samsung Galaxy S Duos which always connects to 2G even though Signal is strong. I tried your method to get it to connect to 3G but it didnt work. There are no settings in the phone to enable manual switching between 2G and 3G.
