The number to customer service is 1-800-922-0204. You will want to call this number from a phone, other than the cell phone, so that when they switch everything over, they are able to assist you in re-programming the cell.

1-800-922-0204 is the customer service number.

You can also set up an online account at www.verizonwireless.com/myaccount and take the battery out of the phone that you want to place on that number and look for the ESN / DEC number. You can enter that number online in your account and change it automatically.

It elimiates hold time waiting for customer service and also doesn't charge you the $20 fee that customer service is supposed to call to switch of the serial number.

Good luck!
