LG phones mainly work with AT&T and Verizon, and the voicemail retrieval system is different for both companies. If you have a generic PIN number for your voicemail on your LG cell phone, you can easily change it to something more private. Verizon requires that you enter a unique PIN--the company does not provide a generic PIN. You should choose a voice mail PIN that is easy for you to remember but difficult for others to figure out.
