Change mobile network mode (gsm, wcdma, auto)

Question

I want to change the preferred network mode ie. gsm or wcdma or auto, programmatically, from code, on Android.

Is this possible, and if so how ?

Answer 1

Answer is NO

We can open directly the settings app of mobile network settings to switch between "2G" and "allow 3G" networks.A direct switch is sadly not possible.

We can develop something which will show current network and allow user short-cut from the app where they can switch network.
