I use this code to change my network type also. While it does display all this information, this code is very useful for changing from 4G to 3G to 2G, and all sorts of other options in between. If you do get this working, look under phone information, then set preferred network type. You'll have to read up on which type means what for your type of network, but this has allowed me to get better battery life and, at times, better cell service even with a 2G network.
