Privacy is very much important on iPhone as it is very much important for everyone’s life. Data such as text messing, social networking, payment and business. So if you are thinking of selling your old device with the new one then first and the most important thing which you need to do, is to prevent your personal information from being leaked.

  • Click on Voicemail from the menu
  • Scroll down to the bottom and hit  “Deleted” to access all deleted voicemails
