Some banks or websites restrict OTP delivery to VoIP numbers. If possible, use an alternate number or contact the provider for manual verification.
The call will disconnect immediately when your balance reaches zero. Enable auto-recharge to prevent interruptions.
Allow CallMama to access your phone contacts in permission settings. Without this, only numbers are displayed.
Make sure notifications are enabled for both your phone and the CallMama app. Also check if “Do Not Disturb” mode is active.
