Updating the PRL locates the nearest cell phone tower in your area that can provide you with the best signal to make calls and send and receive data.Select the option "System Updates," and then "Update PRL." Your device will automatically try to locate the nearest cell phone tower in your area. Dial *228 from your cell phone and press "Send." Wait for the automated menu to play.
