How — Do You Unblock Unknown Numbers

Many Android phones (Samsung, LG, Nokia) use Hiya or a similar spam database. If you have "Spam Protection" on, unknown numbers might be silently rejected before they ring. You must go into the Phone app settings and disable "Caller ID & spam protection" to truly unblock all unknowns.

Sometimes "unknown numbers" are actually known numbers saved incorrectly. If your phone blocks "unknowns," but a client calls from their office switchboard (which shows as "No Caller ID"), you have a contact issue. Save the office main line as a contact with the extension in the notes. This bypasses the block without exposing you to random spammers. how do you unblock unknown numbers
