Paying with Pay As You Go 

Pay As You Go is a payment system that allows you to use residential proxies without buying a monthly subscription. You can access Pay As You Go on the dashboard and purchase GBs for Smartproxy's residential proxies with it. 

This payment system is only available with Smart Wallet. Thus you have to top up your Smart Wallet, and only then you'll be able to use Pay As You Go. With Pay As You Go, 1GB costs $12.5 (note that one Smart Wallet credit equals one dollar), and you can purchase only one GB at a time. After you use 90% of 1GB, you'll be automatically charged for the next GB. So don't forget to turn Pay As You Go off when you don't need it. Payments for Pay As You Go are non-refundable.

If, after you've turned Pay As You Go off, you still have any unused traffic, you can use it within 12 months.

Be aware that you can't have a monthly subscription plan and Pay As You Go simultaneously.
