Camp Mobile, an app developer that was acquired by Line last year has just announced that its mobile app, Whoscall, which is designed to protect users from “smishing,” or SMS phishing, has passed the 10-million-mark in cumulative downloads in about 40 countries worldwide.

The downloading of Whoscall is now active in about 40 countries, with the mobile app being selected as the Best App of the Year 2013 at Google Play in seven countries, including Taiwan, Thailand, and Vietnam.

Having reached 5M downloads in December 2013, Whoscall achieved more than 100% growth within the last two months and has now passed the 10M download mark.

Whoscall has enjoyed popularity mainly overseas, but is also now gaining more acceptance in Korea as the smishing problem is getting more serious among Korean mobile users.

Whoscall is designed to allow users to check caller information before answering a call, as well as to protect users from spam, including via sms. By using phone number databases throughout the world (600M numbers tracked), Whoscall has become a must-have smartphone app for mobile users.
