I gave my Fascinate to my granddaughter to use and put it on the month to month billing. I have been searching the website on how to terminate this service. I am keeping my service for my Droid M.
If you have two lines? Or did you upgrade and just kept the old phone as a toy? Depending on which it is, you can call customer care for help, if you upgraded and kept the old device, it will have no active vzw service, just a internet device now.
