Go into your settings, select wireless& networks... select mobile networks.... then. Select network mode.... select cdma only.... lte is 4g.... hope this helps???
Hey, if you meant 'set' not "sent" then you can get this ap from the android market and it goes to the setting page on your phone allowing you to switch.
If you don't like this option, you could go to the setting yourself under settings>wireless and networks>mobile networks>network mode and choose cdma only.
