I just added a new line on my prepaid account. How do I set up the 4-digit security code for that line? It's working and everything, but I need to register that line so I can login using my new line in Verizon or my Verizon, and it's asking for a 4-digit security code which was never set up. I just put in the sim on my Android phone (bring your own device), and that's it. It didn't work when I try using my security code for my main line.
