How to hide Caller ID on Android
Your caller ID lets family and friends know that it's you who's calling them by displaying your phone number.
But you may not always want to display your phone number when you make calls.
Most phone companies allow you to turn off caller ID on your Android phone so your phone number doesn't display.
While your Android device might be a little different to the one on screen, the steps to turn off caller ID will be similar.
To turn off caller ID, open Settings, tap Applications, and then tap Phone.
Locate and tap More Settings.
Tap Caller ID.
And select Hide Number.
Caller ID is now turned off for all calls you make and the person you call will see displayed Unknown Caller ID.
