I have been able to disable the different networks (2g/3g) in the past to save battery life. The only options I see in the Wireless & Networks setting is CDMA/LTE and just CDMA. I can't figure out how to disable the data radio all together and still be able to receive texts or calls. Being able to select 2g/3g/4g or data would be best but at least being able to disable data without disabling the phone completely would be something I would want to have back. Any way of doing this with an app or something?
