Block scam calls with blacklist

Add +852* into custom blacklist to block scams with +852 prefix.

Nowadays some phone scammers utilize number spoofing technology to change the incoming phone number to a +852 prefix. You can add the +852 prefix into Call Defender Custom Blacklist for you and your family. Please note that if you are currently using roaming service, this setting will block all calls from Hong Kong. Please apply the setting according to your own situation.

[Block Settings & Exceptions] > [Blacklist] > Click the ＋ at the top right hand side > [Enter a number] > Input +852*

You can add the following prefix as well
+881*
+882*
+883*

You can use +* if you are sure that you never receive oversea calls.

(There are many types of telephone scams. Verify the caller's identity.)
