[DigitalToday reporter Jin-ho Lee] KT M Mobile said on Monday it will offer unlimited data products for four Asian countries at 990 won per day to mark the launch of partner sales for its eSIM roaming service, mobi.

The countries covered by the partner festival are Japan, China, Vietnam and Taiwan. The unlimited-data three-day product costs 2,970 won and the four-day product costs 3,960 won, which comes to 990 won per day.

The special-price products will be available for purchase from July 15 to Aug. 15 through the mobi app and website, the KT M Mobile direct mall, and partner websites including Lotte Duty Free and BC Card.

The company will also provide benefits for Lotte Duty Free. Users can receive discount coupons for Lotte Duty Free's online mall through the mobi app. At the Myeongdong, World Tower, Busan and Jeju stores, customers can receive shopping discount benefits by verifying their purchase history. The benefits will be provided until Feb. 31.

Mobi is an eSIM data roaming service KT M Mobile launched in December last year. It can be used in 59 countries worldwide. Users can receive calls and text messages on their existing number without replacing their existing SIM, while using only data via eSIM.

It also supports "activation check", which verifies activation status in South Korea before departure, and "easy registration", which registers an eSIM with a single button in the app.

Byeon Seok-ju (변석주), head of the Business Operations Division at KT M Mobile, said, "We will make mobi the most convenient travel partner through various partnerships and benefits."
