Auto-recharge, i.e. bind a credit card and when the balance is less than the set amount, the set amount is automatically deducted from the credit card.
This method eliminates the recharge fee and protects the service from being stopped due to non-payment.
This feature can be changed to a different credit card at a later stage and can be stopped at any time. Minimum auto-recharge amount is 5 USD and minimum auto-recharge threshold is 1 USD.
