I've read that IMEI numbers should be 15 or 17 digits long. The Samsung Galaxy Proclaim I have is a Straight Talk phone and the IMEI number is 18 digits long. I know it uses the Verizon/CDMA network. Can anyone tell me why that is? Also, is there a way to get a 15 or 17 digit IMEI from the Straight Talk IMEI?
