Related QNAs

Why is my caller ID not showing correctly?

Some countries restrict outbound caller ID for VoIP. Ensure “Show Caller ID” is toggled on in settings; otherwise, it may appear as anonymous.

Number purchase stuck on ‘Processing’.

Avoid closing the screen during checkout. It may take up to two minutes for confirmation if it’s still stuck, check your internet and retry the purchase.

Why are my messages marked as ‘Undelivered’?

The recipient’s number might be switched off or blocked for VoIP SMS. Try resending later or verifying that the number supports virtual SMS delivery.

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.
