User Reviews

Many reviewers gave brief positive reactions, but the strongest complaints are lack of English localization, forced frequent updates, and authentication problems that block international users. A few also said the app feels redundant because billing can be checked in the T World app.

Pros

Several users left short positive comments ("Good", "Nice", "All the best") indicating basic satisfaction
App appears to function for many users (works after initial hiccups)
Simple/uncomplicated — users gave brief favorable reactions to the app experience

Cons

No English localization — many users complained the app is Korean-only and not usable by foreigners
Forced or frequent update behavior — users reported being forced to update or visit the app store repeatedly
Authentication/verification problems for international users — mandatory identity verification and phone-number checks prevent use while abroad or with suspended lines
Seen as redundant by some — users note they can view bills in the T World app so this app may be unnecessary
