Pingzapper does not offer a "free forever" limited-speed plan like some competitors. Once your 20 hours are used, the software stops working. You cannot tunnel anymore. There is no throttled "free mode"—the service simply asks you to subscribe.
However, there is a well-known (and officially permitted) workaround:
Account Cycling: Because no credit card is required, many users simply create a new free account with a different email address every 20 hours.
While this is technically possible, it is tedious. You lose your saved settings, favorite servers, and have to re-login constantly.
Pingzapper has a referral program. For every friend who signs up and purchases a subscription using your link, you receive free days added to your account. If you have a gaming community, you can stack referrals to effectively play for free for months.
The effectiveness of PingZapper Free depends entirely on your ISP and your geographic location.
The free version is the best way to determine which scenario applies to you.
