Unicom mobile phone user can filter out not to receive text messages, is that true?

Users questions: The specified phone number is added to the blacklist list, no longer receive the messages issued by the mobile phone number.
Experts answer:, of course provided you have a cell phone call firewall!! Or your phone is smart to install firewall software!! Finally you can call customer service to China Unicom, said the other harass you! To Unicom to deal with!!
