Does keyword-blocking block phone number with the keyword, or just blockes SMS?

Hi, I am using latest Comodo Mobile Security. and I have a question on keyword-blocking.

If I want to block any phone numbers which contain a specific keyword, such as ‘11111’, can I use keyword-blocking ?
Or, the keyword-blocking just blocks the short message with the keyword.

Thanks.

Hi,

Keyword locking is for SMS contents. you can see more help on below link.
