Dial a caller ID block code before the phone number. In the USA, dial *67 proceeding the number. In the UK, dial 141. So for example if you need to call 212-555-5555, Dial *67â¦-212-555-555 instead. Your caller will see a message that says caller ID blocked..
On a UK mobile phone, on some phones, 141 before the number also works. However, it does not work on ALL mobile phones. On some, you should use #31# instead. Also, on some other UK mobile phones, there is a special call option HIDE NUMBER in one of the many menus and options which can be a bit fiddly at times.On some snazzy mobile phones, you can choose the people who are allowed to know your phone number, and those from whom to keep your number secret.lso, on some other UK mobile phones, there is a special call option HIDE NUMBER in one of the many menus and options which can be a bit fiddly at times.
