User Reviews

Users frequently report that the OCN アプリ crashes or fails to start, and has significant login problems. The app only supports Japanese, making it difficult for non-Japanese speakers to use. Widgets often do not work properly, and the app is not fully compatible with newer Android versions, resulting in poor responsiveness. Some users appreciate the packet mode switching feature and recognize it as part of the NTT group. Overall, the app suffers from reliability and usability issues based on multiple user reviews.

Pros

Useful feature to enable switch packet mode
Part of NTT group which implies some reliability
Some users found the app itself functioning without major problems

Cons

App crashes frequently and does not start on some devices
Poor language support, only in Japanese, making it unusable for tourists or non-Japanese speakers
Login issues and error messages preventing access
Widget functionality is broken or poorly designed
App has poor responsiveness and compatibility issues with newer Android versions
