The Samsung Galaxy S4 smartphone enables you to hide your phone number when you place a call. The Hide Number feature helps you protect your phone number if you are calling a stranger or if you don’t want to be called back. The feature can be turned on directly on the phone and is carrier-independent. The recipient will see an “Unknown Caller” or “Unknown Number” message instead of your phone number, but don’t forget to turn off the feature if you want to place regular phone calls. Using the Hide Number feature is free. Tips Warnings Writer Bio
