To keep your numbers active you have two options
1) Monthly Number Renewal from Credit Card
2) Monthly Number Renewal from Account Balance
To set your number to renew by Credit Card each month when you purchase a number visit
and choose a number, then click "continue".
Next choose "credit card" as the payment method and check the box that says "check if you want to save card for auto renewal" and complete checkout.
To pay for your monthly services using withdrawal from your account balance, and to keep your account balance positive at all times
Under "setting" select "auto reload" and enter an amount, that is more than your total services (all classic and premium numbers). For example. If you have three numbers at $4.99/month your total monthly cost for the numbers comes to $14.97. You would want to set the auto-reload to charge $15 when the balance drops below $5.
