If you want to keep your number hidden on your iPhone 6, there are a few different ways to go about it. The first option is to turn off the display of your number on the lock screen. To do this, open the Settings app and tap on “General.” Under “Privacy,” select “Show My Number on Lock Screen.” If you don’t want anyone to be able to call you even if they have your number, you can also turn off the contact list in the Phone app. To do this, open the Phone app and tap on “Contacts.” Under “Options,” select “Don’t Show My Number When Calling.” Finally, if you want to keep your number hidden but still be able to receive calls from specific people, you can add those people to a VIP list in the Phone app. To do this, open the Phone app and tap on “VIPs.” Under “Options,” select “Add People.” Then enter their phone numbers and tap OK. ..
