For cell phones call from the cell phone 888-3821222
I know
Telemarketers and people who do telephone research or charities are not allowed to call any cell phones by law. If they accidentaly call your number, just tell them it's a cell phone and they won't call you again.
It is not nearly as common as telemarketer calls to landline phones since it is usually illegal for telemarketers to call wireless phone numbers. It does still happen, though users can register their number with the national do-not-call registry.
Type "*67" before the number.
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!
YOu can get the app Mr. Number
Depends on what cell phone it is.
Call customer service or see if there is an instruction manual for your phone.
You call your servize provider and tell them to block that number that you want blocked
Some cell phone companies may not allow voices messages to be left when a number has been blocked, while other cell phone companies will allow a voice message.
To block a number, simply dial *60, then press the hash key. Once you hear the dial tone, type in the number that you wish to block, followed by the hash key. This will block the number.
It depends on your carrier, but yes, you can. Not from your phone: you will probably have to call your service provider and have an operator/CSR block the number manually. But it is definitely possible.
some land line phone companies allow you to block all private or unknown numbers......If you can check your account from your computer you can do it that way or call your phone company. As far as cell phones Im unsure.
