When someone doesn't want to talk to you, he or she will block your number. You won't be able to call that person.
That depends on your phone company, and may also depend on what brand of phone you have.
Hang up and call the police to trace the number.
Traffic accident! call 911 or somebody who can help!
You can't. the only way you can block a number is to call your provider
press the block button
*67
You can call someone without showing your own number by dialing star symbol67 before you dial the phone number you wish to call. this blocks your number just on this call, not permanently. If you want to block your number permanently go into your phone's menu settings and look for the option to block your number.
Maybe you should call them but block your number, and find out who they are. :)
If you need to then call for somebody. not call somebody yell for somebody. that's what I do.
To block a number on 'at' - you have to call your credit number, and you credit number should give you some options. It should say, and for anything else please press (for example) 4. Press this, then press 5. And it will ask you if you want to unlock your phone, or block a number. Press 2 to block a number, then click options, keypad, type in number, then you click phonebook, and click the number you want to block. Then give your details to pay £5 Or $7 to block a number. :] Hope This Helps!
