Visual Data Remaining at a Glance
To check the remaining data, users simply open the app. The current data balance is displayed clearly in a pie chart, offering a visual representation of usage. This visual aid assists users in determining when a data top-up might be necessary based on their daily consumption patterns.
Timely Notifications for Data and Expiry
Users no longer need to manually check their data balance or expiration dates repeatedly. The app delivers email and push notifications at crucial times, provided app notifications are enabled.

The notification timings for Wi-Fi and SIM services are as follows:
| WiFi Service | SIM Service |
|---|---|
| Data remaining at 1GB or less, or 0GB | Data remaining at 1GB or less, or 0GB |
| Data validity 7 days before or on the day | Data validity 7 days before or on the day |
| Recharge availability 7 days or 3 days before |
These notifications help prevent situations where users might unknowingly exceed their data limit or miss an expiration date, ensuring they can check and recharge data when needed.

Simple In-App Data Charging
When users determine they need more data, they can easily proceed to recharge directly from the app without searching for external services or pages. This feature is particularly useful when data is unexpectedly needed while traveling or on the go. The app integrates data checking, notifications, and charging to provide a seamless experience for adding data as required.
Biometric Authentication for Smooth Login
The official app supports biometric authentication, including Face ID and fingerprint recognition. Utilizing biometric authentication allows users to access their My Page and confirm charges without the inconvenience of entering IDs and passwords. This ensures a secure and smooth service experience while reducing the effort of repeated password entry.
