With eBay being one of the biggest marketplaces to buy and sell used phones, it makes sense that the site is now offering prepaid wireless plans as an add-on option in the item listing. A checkbox underneath the “Add to cart” button offers a 30-day unlimited wireless plan from Red Pocket Mobile for $29, and an option to upgrade to various 360-day plans when checked.

The release of Apple’s new iPhone XS and XS Max, plus the upcoming release of the Google Pixel 3 means it’s prime phone flipping season. As people begin to sell their old smartphones on eBay, buyers looking for secondhand devices can take the opportunity to pick up a wireless plan during checkout. Red Pocket is an MVNO that lets subscribers choose any major carrier they want to use, which is likely a big reason that eBay chose to partner with the company.

It’s a partnership that makes a lot of sense for both companies, and anyone looking for affordable smartphone options. eBay is a good place to start looking for secondhand devices, considering how often the site has deals on tech products.
