Block Unknown Callers

Comodo Mobile Security - CMS

Is there a way to block unknown callers with Comodo Mobile security?

You might from importing the call logs (that option I never tried though).

My phone has a block feature (just for calls) in the menu (Call Rejection) that will block unknown calls.

Thanks John. I tried the import from call log, but that did not work. It imports a “-1” number from unknowns, which is not how called ID shows an unknown call. My phone (RAZR) does not have that feature built-in that I can tell.
