マイページアプリ is an Android app developed by 株式会社Suggestum in the category of Social & Communication. This free app allows users to easily manage their monthly usage fees and check their registration information.

The app offers several key features. Firstly, users can easily check their usage fees for their FREETEL SIM and monthly options. It provides a convenient way to review the usage status for the current month as well as the past three months.

Additionally, users can access and verify their registration and payment information that was provided during the contract process. This helps users stay informed about their personal details and payment methods.

Furthermore, the app allows users to check their current contract status, including the pricing plans and monthly options for their SIM service.

Another useful feature is the ability to switch the "savings mode" of the SIM service on or off. Users can easily toggle the savings mode, which limits the maximum data transfer speed to 200kbps.

Overall, マイページアプリ is a convenient app for FREETEL SIM users to manage their usage and access important account information.
