투넘버 문자 is a lifestyle application developed by remain.corp. It allows users to easily manage multiple phone numbers on their iPhones. With this app, users can conveniently handle their *77 and *281 numbers in one place, making it simple to send and receive messages. The latest update includes a complete redesign of the user interface and style, providing a fresh and modern look. Additionally, users can now display the caller's information by saving the numbers in their Two Number contacts, eliminating the need to store them in their phone's address book. The login feature has been removed, allowing users to back up their data using their iCloud account. Another new feature is the support for Uplus Talk Talk Dual Numbers. For any issues or suggestions, users can contact the developer through the app's settings.
