Dialing just a single asterisk (*) usually does nothing or might trigger a network error, but dialing specific codes starting with * (like *73 for call forwarding or *82 to unblock caller ID) activates special phone features, while some codes (like *#002#) check settings or disable call forwarding for security, often used for carrier services and phone functions, not just a standalone symbol.
To confirm the phone numbers registered in your name dial *106#. To prevent your sim being swapped without you present dial *100*100#. If someone tries to register a new line using your ID you will receive an SMS from 707 asking you to confirm that you are registering a new line.
Dialing *#002# disables all carrier-based unconditional call forwarding instructions, meaning incoming calls will stop being redirected to other numbers.
To turn off Call Forwarding from your mobile phone, call *73. You should hear a confirmation tone or message that may sound like a busy signal to let you know Call Forwarding has been turned off.
You can't use *86 to call on another phone - it will connect to the voicemail of the calling phone. From another phone, you need to dial your own number. When your greeting starts to play, press #, then your password and #. The voicemail icon is the Visual Voicemail app - not *86.
This Vertical Service Code, *82, enables calling line identification regardless of subscriber preference, dialed to unblock withheld numbers (private callers) in the U.S. on a per-call basis.

It is the code ##002#, a feature built into most cell phones, whether Android or iPhone, which allows you to remove all active call forwarding on the line, just by dialing it from the call app.

Can spoofed calls be traced? Yes, but tracing spoofed calls can be difficult. While law enforcement and telecom providers can sometimes trace calls to their origin, fraudsters often use anonymizing technologies or overseas infrastructure to evade detection.
Dialing *77 on your phone activates Anonymous Call Rejection, blocking incoming calls from private or blocked numbers, making anonymous callers hear a message to hang up and try again. It's a landline/VoIP feature (like AT&T, CenturyLink) to stop spam/prank calls but can sometimes vary by carrier or state, potentially connecting to emergency services (like *87 to turn it off).
Call Waiting: 43 (Various Combinations)
I reactivated the voice call waiting specifically with *#43#, and confirmed it in the iPhone's Settings > Phone > Call Waiting menu. It should be the same code for T-Mobile. On Verizon, using *43 will deactivate call forwarding, not call waiting; *42 will turn it back on.

Yes, \*67 still generally works on most U.S. carriers to block your caller ID for a single call by dialing \*67 followed by the number (e.g., \*675551234567), showing up as "Private" or "Blocked," but it won't work for toll-free or emergency numbers and may be blocked by some recipients. This per-call feature hides your number but doesn't change your phone's settings permanently, and you can use other methods like carrier settings or apps for consistent blocking, notes USA Today and Times of India.
If no one answers or the line is busy, the dialing sequence must be repeated to effect call forwarding. Call forwarding is disabled by dialing *73.
Caller-ID Blocking can protect your privacy when calling people, not allowing them to see your information. Keep in mind that Caller-ID Blocking does not work when calling 800 numbers or 911. Note: Dialing [*67] before your call will only block Caller-ID for the duration of that call.
