Go to your phone’s app permissions → enable “Microphone Access” for CallMama. Without it, others can’t hear you.
Your messages are tied to your CallMama account, not your SIM. Log back in using your same credentials to recover them.
This can occur after an app update. Restart or reinstall the app — it will re-sync all features.
Battery optimization or data saver mode can interrupt ongoing VoIP calls. Add CallMama to your phone’s “Unrestricted Apps” list.
Duplicate messages can appear if your app fails to sync properly. Clear your cache or restart the app to remove duplicates.
