Users can add up to four numbers, including local and "Easy Number" Mainland Mobile Numbers, facilitating seamless communication both locally and in Mainland China. With straightforward registration and no contract requirements for daily plans, users can quickly start using additional numbers.

User Reviews

Users report that the app is unstable with frequent crashes and slow startup. It demands excessive permissions, raising privacy concerns. SMS notifications are unreliable and often require manual app opening to receive messages, resulting in missed communications. Message management is cumbersome, with no multi-select deletion and automatic deletion of messages. Overall, the app is considered poorly designed, with performance and usability issues.

Pros

Cons

The app frequently crashes or fails to open, causing significant usability issues.
It requires excessive and intrusive permissions unrelated to its core functionality (e.g., access to music, photos).
The app does not receive or notify SMS messages properly unless the app is opened manually, leading to missed messages.
Deleting messages is tedious and inefficient, often requiring individual message deletion without multi-select functionality.
The app has slow startup times and poor overall performance, including delayed notifications and battery drain.

Recent reviews

This app cannot receive an authentication code or SMS unless you open the app. So it's pretty dumb and useless. Also, deleting SMS is a tedious task that involves opening every bubble in each SMS to delete individually. Takes ages to delete. Always a time lag to receive an SMS.
