Yes, absolutely! You can temporarily show your caller ID by entering the 82 code for one phone call. Similarly, you can reenable the "Show My Caller ID" feature and unhide your number by following the same steps. Depending on your provider, you may be required to wait for a quick dial tone after you enter 82 before entering the area code (if necessary) and the phone number. It might get tiring after a while because you need to enter 82 before every single call to keep it private. Consequently, if most of your conversations are with friends and family, you may want to leave your caller ID visible and enter the 67 code when it needs to be hidden.
