Review summary

OneSim VoIP is praised for affordable international calls and recent interface improvements. However, users commonly report frequent app crashes, persistent login issues after updates, inconsistent call and messaging performance, and subpar customer support. Some note the requirement for high minimum credit purchase and occasional offline errors despite connectivity. Overall, the app serves its purpose for low-cost international calls but suffers from stability and usability problems that undermine user experience.

Latest update improved interface and added features like call waiting.
Continues to work with Android 9.
Provides a business service appreciated by some users.

Cons

App crashes frequently causing interruptions.
Login/sign-in issues after recent updates prevent access.
Inconsistent performance with sending/receiving messages and calls.
Poor customer service and lack of effective support.
High minimum credit purchase and occasional offline errors despite internet connection.
