turn off show my caller ID in phone sertungs not e

There are several reasons you may not be able to turn off Caller ID from your phone:

• Your carrier doesn’t support the switch on the phone - you have to call them
• The laws of your country don’t allow you to block your caller ID
• You have a business or school account on your phone and the administration does not want you to block your caller ID.
• Your phone is under an MDM (Mobile Device Management) plan
