While using Zang services (voice minutes, SMS, name and address lookups, etc.) we deduct from your pre-paid account balance. When your account balance hits $0.00, your account will be temporarily suspended until additional funds are added. We notify you by email when your balance gets down to $10.00, so you can plan accordingly.
If your balance reaches $0.00 you will no longer be able to use any of Zang’s features or the phone numbers that you have purchased. However, you will NOT lose any phone numbers you've purchased right away. You'll want to head to our billing page and add funds to your account to reactivate your numbers and your Zang service.
In the case that you have not replenished your Zang account after 60 days, we may close your account and return your phone numbers to our database of available numbers. This means it is important to proactively take care of your account’s billing and avoid any disruption to your applications.
If you want to cancel your account simply stop funding it. Once your balance reaches zero we’ll automatically shut off your account.
