Before you dispose of a computer, get rid of all the personal information it stores. Use a wipe utility program to overwrite the entire hard drive.
Before you dispose of a mobile device, check your owner’s manual, the service provider’s website, or the device manufacturer’s website for information on how to delete information permanently, and how to save or transfer information to a new device. Remove the memory or subscriber identity module (SIM) card from a mobile device. Remove the phone book, lists of calls made and received, voicemails, messages sent and received, organizer folders, web search history, and photos.
