Related QNAs

I can’t find my purchased number.

Go to My Numbers → Active Numbers and refresh the page. Logging out and back in forces a full sync from our server if it doesn’t appear right away.

Can I get a refund for unused numbers?

Yes, if the number hasn’t been used or assigned within seven days. Contact our support team and provide your purchase reference for verification.

The app doesn’t access my microphone.
