If you just want to call using a different number than your own, consider using Google Voice instead of blocking your number.

Set up Google Voice

Google Voice is a free app that allows you to place calls using a different number from your standard mobile number. Before you use Google Voice, you need to download it from the App Store or Google Play Store. When you place your first call using the Google Voice app, you will be asked to search for and select a number to use. Follow the on-screen instructions to select a number to use with Google Voice.

  • You can also text anonymously by using Google Voice.


  • If the person whom you’re calling has an app that unmasks your private phone number, they’ll be able to see your real phone number.
