Your residential data can be roll overed, if you have topped up your bandwidth within 30 days (premium) or 50 days (select) from last purchase. ## What happens to the expiry date? For example, if you've purchased the premium proxies, the expiry date will be set to 30 days from day of purchase unless you purchase more proxies. In other words, if you purchase every 29th day, then your data will remain in your account for 30 days from your most recent purchase. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs-proxies.zesty.group/residential-information/data-roll-over.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
