Speaking of faking people out, you can get temporary phone numbers for iPhone and Android. Use these for both incoming and outgoing voice calls. You can add each “burner” as a contact and even create custom voicemail messages. This app is ideal during Craigslist or Airbnb exchanges, and for avoiding nagging merchants and other questionable types.
Cost: Free temporary test “burner” plus credit packs available from $1.99-$11.99 (note: “burners” do use cell phone minutes also)
