Why do calls drop instantly after dialing?

Instant disconnection usually means:

Incorrect dialing format (always start with +country code).
Weak network or insufficient credits.
Recheck both and retry.

Related QNAs

Voice sounds robotic or metallic during calls.

That happens when network packets are lost in transmission. Reconnect to a stable signal to restore normal audio clarity.

Why is my invoice not showing?

Invoices are generated automatically but can take a few minutes. Refresh the “Billing History” section or re-login to view recent transactions.

Can I port my existing number to CallMama?

Yes, most carriers support port-in requests. Contact support with your current provider details to start the process.

My number isn’t activating after payment.

Activation usually completes within minutes, but delays can occur.

Restart the app or log out and back in.
Ensure your payment was successfully processed.
If still inactive after 10 minutes, contact support@callmama.com with your transaction ID.
