There may be times when you do not want the person you are calling to view the phone number. The reasons why you should imagine the cell number:
o You do not want the person you call to see that they called them ten times in turn.
o You do not know the person you are calling and do not want to have access to your number.
o You have called a business or an unknown number, and you do not want them to know your number.
If you decide to keep the cell phone secret, you have to count the number. The blocking of its number can be temporarily or permanently enforced. Temporarily disable your number on a call based on a call, a good idea if only a few people want to hide their number. Your number is temporarily blocked so it does not appear in the recipient's caller ID before dialing the number (IE * 67 111-111-1111).
Remember, you should know that whenever * 67 temporarily disables yours, there will be no information that your number has been successfully blocked. So if you make sure it works, be sure to check it out quickly and first call your home phone number before using this service with someone else.
If you really want your mobile number to be private and permanently banned your mobile phone number, you need to contact your wireless service provider and request a "line block". Once you've created the line block, the number will not appear to anyone. However, if you want the phone number to be displayed to a recipient for some reason, you can dial * 82 before dialing the phone number.
Finally, you need to know that your cell phone number is not blocked either by toll-free (IE 800 numbers) or by emergency services.
Additionally, it may be a good idea to block the number of your mobile phone if you try to find out who has a phone number by recalling the mystery number.
