How to: Turn Off 4G on Verizon’s Galaxy S3

For whatever reason, turning off 4G LTE on Verizon’s version of the Samsung Galaxy S3 has been made extra difficult. The menu under Settings>Wireless and network>More does not include the old toggle that we use on devices like the Galaxy Nexus. You are also unable to type in *#*#4636#*#* to get into the phone info menu and change it manually through there. I even downloaded the Thunderbolt LTE toggle, which works on the RAZR running Ice Cream Sandwich, and found nothing but force closes.

Thankfully, this app called Phone Info works like a charm. Install it, open it, and head into “Device information.” From there, you’ll need to scroll down to the pull down menu which probably says “LTE/CDMA/EvDo” and choose “CDMA auto (PRL)” to turn your phone into a 3G, battery saving machine.
