This section outlines the tools available to help you manage your account balance efficiently and ensure uninterrupted service. By combining features such as auto-charge, payment prioritization, automatic top-ups, and low balance alerts, you can create a reliable and flexible billing strategy.
Use the Auto-charge toggle in the corresponding row to enable or disable the feature.
Important
The Auto Balance Top-Up feature only works if Auto-charge is enabled on your primary payment method. If disabled, no automatic payments will be processed, even if the low balance threshold is reached.
When multiple payment methods have auto-charge enabled, you can define the order in which they are used by setting their priority. The method at the top of the list, marked with a star icon, is treated as the primary method for all automated transactions.
Go to Billing > Payment Methods.
Click and hold the ☰ icon next to the payment method you wish to prioritize.
Drag it to the top of the list and release. The star icon will move to indicate the new primary method.
Note
If a charge to the primary payment method fails (e.g., due to insufficient funds or a bank decline), the system will automatically attempt to charge the next available method that has the auto-charge toggle enabled.
The Automatically refill when threshold is reached setting ensures that your balance is replenished automatically whenever it falls below the specified threshold.
Go to Billing > Payment Methods.
Enable Automatically refill when threshold is reached toggle.
Set the following values:
Threshold amount – the balance trigger point.
Refill amount – how much to add when triggered.
Click Apply Changes.
Warning
This feature requires at least one of your payment methods to have auto-charge enabled.
Hint
If your account has active calls, the final charge is only calculated after the call ends. The top-up trigger will only activate once the balance is updated. To avoid service disruption in such cases, it is strongly recommended to set a higher minimum threshold (e.g., 50 USD) to ensure sufficient buffer for active call costs.
Configure a Low Balance Notification to receive an email alert when your account balance drops below a specified threshold. This option is useful if you prefer to manage payments manually or want a warning before automatic top-ups occur.
Navigate to Payments > Payment Methods.
Toggle Low Balance Notification to enabled.
Enter your desired threshold amount.
Click Apply Changes.
Important
Combine this with Auto Balance Top-Up for layered protection (e.g., set a higher notification threshold than the auto-top-up trigger).
This feature only sends notifications—it does not trigger any payment action.
If an auto-charge or manual payment fails, the associated payment method (e.g., credit card or PayPal) becomes temporarily unavailable for further automatic billing for 48 hours. Common reasons include:
Insufficient funds
Card expired or invalid
Bank declines the transaction
Authentication failure (e.g., 3D Secure verification)
When this happens, a Retry button appears next to the failed transaction. Click Retry to manually attempt the payment and restore the payment method.
