Why are so many telemarketers able to call personal cell phone!!!   HUH!!!

Um ...
Because they have telephones  too!
That is what telephones are for ... calling other telephones.
Spammers and scammers are criminals, and they ignore the laws prohibiting cold calls to cells.

Care to clarify your question?
