Hi there and welcome
The question it will be asking is to rpvide the serial number of the phone
To obtain the serial number simply remove the battery from your wireless phone. The serial number is ***** 11 or 15 digit number located on the white sticker on the back of the phone.The serial number will be after the letters "ESN","IMEI""SN","DEC", or "Serial No".
For some Motorola and Nokia phone models you can also find the serial number on your TracFone display. To find the serial number, press Menu and select the Prepaid menu. Scroll down to My ESN, IMEI or Serial No. and press Select, if necessary.
