This application provides an exclusive service specifically for users of Rain's rainone mobile service. It is designed to enhance the communication experience for those who are part of the rainone network, offering specialized features that are not available to other users.
The core benefit of this service is its reliance on Rain's new 4G-only network, which eliminates the use of outdated 2G or 3G networks. By focusing solely on 4G technology, the network allows users to experience high-definition voice calls, thanks to the implementation of VoLTE technology, ensuring clearer and more reliable call quality.
For users whose devices are not compatible with VoLTE, the application still provides an alternative. These users can access HD calling through a feature called raintalk, which does not require upgrading their smartphones. This ensures that all rainone users can enjoy high-quality voice communication regardless of their device capabilities.
The application is designed to be simple and user-friendly, resembling a standard built-in dialer, so users can easily make calls. It offers the convenience of HD calling without the need for new devices, making it accessible and easy to use for all rainone customers who wish to improve their voice call quality.
