Auto-recharge is a feature that automatically tops up your account with SMS credit when your balance falls below a certain amount.
This ensures that you never run out of credit and prevents unexpected service interruption.
Auto-recharge works with credit cards and PayPal. With Auto-recharge, your credit card or PayPal account is debited in the same way as if you were making a manual purchase, but with Auto-recharge enabled, you don´t need to approve each payment.
Be aware that automatically recharging your credit is not the same thing as having a subscription although both involve recurring payments.
