  1. 1

    Download SpoofApp. Go to the SpoofApp website and follow the link to the "Install" section. There, select "iPhone" and follow the instructions for downloading the software onto your computer. After you have downloaded the app onto your computer, you will have to sync your iPhone before you can use it.

    Purchase minutes. The first five minutes are free, but after that you will need to "Add Minutes," which you can do in the section by the same name on the SpoofApp website.

  3. 3

    Open SpoofApp on your iPhone and enter in the number you wish to call. You can also select one from your contacts.

  4. 4

    Enter the number you wish the caller's phone to display. You can choose to appear as one of your contacts or as somebody else.

  5. 5

    Select the voice you wish to use. Under "Voice Changer" in the app, you can choose "Normal," "Man" or "Woman."

  6. 6

    Choose other options. You can decide whether to record the call and have it go straight to voicemail.

  7. 7

    Hit "Place Call" at the bottom of the screen. SpoofApp will place the call.
