There are 2 ways in which you can hide your caller ID. The first way I’ll show to you is the easiest and quickest to do. What ever the reason may be for your intentions to conceal your caller ID – every one deserves privacy at some point.  Now, lets get down to it.
  1. Just dial  #31#  followed by the cell number you wish to call then press the dial button on your phone. That’s it, your phone number has been concealed. [ #31# ‘number’ then dial button]                                                                                                      
                                                       
  2. The 2nd is for people who want to (i think) keep their phone numbers private for a very long time, because with this one you wont have to keep pressing  #31# every time you dial a number. Not sure why would some one want to conceal their numbers for “ever” but in case you are that person, here’s how to do it.
  • On most phones you go to ‘menu’, ‘settings’, ‘call settings’ , ‘caller ID’ then choose ‘private’ / ‘hide’ or something similar. Done! Remember, you’ll have to go back and disable private number if you want your number to show. Disabling is the same as enabling except instead of ‘hide’ you choose ‘show’ or something similar.
