ok so i have a pre paid verizon LG phone and i want to transfer it to my new pre paid verizon samsung which is the intensity. the thing is my intensity is locked because i re activated it with a new number earlier today and switched the old number with this new number that i never wrote down so now i don't know the security code to unlock the phone all i know is my number started with 315 709 **** and the last four digits are the numbers of the security code to unlock the phone does anyone know what i could do to find out my number seeing how i cant get a hold of a verizon customer representative without knowing the number and how to unlock the phone please help thank you
