LTE Toggle on AT&T S4

For anyone looking to regain the ability to toggle radio bands (typically, to save battery in weak or no LTE reception areas) that went away with the latest 4.3 update, here's the next best thing.
  1. Go into Settings > More networks > Mobile networks > Access Point Names
  2. Press the + sign at the bottom of screen
  3. Add the following entries (note text cAsE):
    Name: ATT -LTE (this is just a label for your own use - you can use any name)
    APN: wap.cingular
    Proxy: leave blank
    Port: leave blank
    Server: leave blank
    MMSC: http://mmsc.cingular.com
    Multimedia message proxy: wireless.cingular.com
    MMS Port: 8080
    APN Type: leave blank
Now, to configure a quick toggle shortcut, use one of the following methods:
  • If you are using a launcher that allows direct shortcuts (e.g., Apex or Nova):
    Shortcuts > Activities > Settings > APNs
    (this will create a direct shortcut to the APN selection screen, buried at step 1, above)
  • If you are using stock Touchwiz or a launcher without shortcut capability, you can accomplish the same thing with the xShortcut FREE app.
Turning off LTE can really be a battery extender for those times when you don't need it or don't have reliable access. Disabling it does not change anything else (i.e., 3G/2G/Edge speed negotiation continues to work normally, as before).

Enjoy! :tee:
