The international call button is greyed out.

Why is my call getting muted automatically?

Auto-mute may be active in your settings or triggered by your phone’s proximity sensor. Disable it in app preferences and retry.

Why is the “Buy Number” option not showing for me?

This usually happens when your CallMama account is not verified. Go to Profile → Verify Email / Phone, complete verification, and restart the app.

I can’t make international calls from the app.

Before placing calls:

• Check that you have active calling credits.
• Make sure international calling is enabled on your plan.
• Some countries may be temporarily restricted — check the supported destinations list.
