LINE Whoscall is most useful for blocking unwanted calls that might be malicious, or, quite simply, just a waste of your time. To accomplish this, LINE Whoscall has a database of more than 600 million telephone numbers.
Once they receive a number's information, users of the application can decide if they want to block that number from calling again. This means that that number will not be able to contact you again, whether it be by call or text.
In addition to all of this, LINE Whoscall has an offline database that you can access at any time to look up telephone numbers, without needing an internet connection.
LINE Whoscall is a very useful tool for freeing yourself, once and for all, of all those unwanted, pesky calls that always manage to bother at the worst moment.
Requires Android 2.2 or higher.
