Remember, you must keep your PSTN (Prepaid) calling balance positive in order to make and receive calls to/from the PSTN (traditional 10-digit numbers).
The auto-refill feature is the best way to keep your account balance positive and avoid interruption of service. If you use this feature, we will automatically charge your credit card on file when your PSTN (Prepaid) account balance falls to a certain level. We will charge your credit card whatever amount is necessary to return your balance to a level you choose.
In order to use Auto-Refill, you will need a valid credit card on file in your account.
Step 1: Locate Auto-Refill by navigating to the "Account" tab, and click on the "Configure auto-refill" link under the PSTN (Prepaid) heading.
Step 2: In the dropdown menu next to "When credits drop below", choose the amount that you want the Auto-Refill function to start (the THRESHOLD amount).
Step 3: In the dropdown menu directly below (next to "Top credits up to"), choose the amount that you want your available credit balance to be replenished to (the RECHARGE amount).
Step 4: Click on the "Save" link in the lower right corner of the "Auto-Refill" box.
Now, when your credit balance drops below $5.00, we will automatically charge your credit card whatever amount is necessary to bring your balance back to $50.00! Please note that the charge will not necessarily be $45.00. Calls do not get charged to your account until they are completed. For instance, say you have $5.05 for available credit, and you make a call that costs $0.15. That amount will get deducted once you complete the call and hang up. Your credit balance will then be reduced to $4.90. Only then will Auto-Refill kick in and charge your credit card $45.10 to bring your available credit balance back to $50.00.
Once this is performed, a receipt via email of the transaction will be sent to the email address you have listed on your account.
