How does Call Display work on my mobile?
Call Display lets you see the caller’s number on your mobile. If you’ve subscribed to this service, you don’t need to do anything to use this feature. The phone numbers of those who call you will be automatically displayed on your screen when calls come in. If a given number is saved on your mobile or SIM card, you’ll also see your contact’s name and photo.
How do I block my cell phone number when I want to make a call?
You can block your cell phone number permanently through your phone’s settings. Refer to your device’s user guide for more information. To block your cell phone number temporarily, simply dial #31# and then the phone number before pressing the call button.
Good to know
If you receive calls whose number is not displayed, this means the caller has blocked their number. You can reject these calls by activating the Anonymous Call Rejection feature on your phone.
