The South Korean electronics giant is billing the promotion as the "ultimate test drive" and it allows U.S. customers to trial the dual-curved screen Galaxy S6 Edge, S6 Edge Plus and the Note 5 for with full cellular service for 30 days.
An activated SIM card with a voice and data plan hosted by a user's current carrier is included in the trial.
But users can only sign up to the promotion via Samsung's website through an iPhone. So anyone using a Windows or Android phone won't be eligible.
If a customer likes the Samsung phone, they can buy the device and the company says that "There's even more love in store for you" if you do. There's no indication what this could mean.
If a customer is not keen on the device, they can send it back in a pre-paid package.
Samsung struggled in the smartphone market last year as it was pressured at the high end by the release of Apple's iPhone 6 and larger screen iPhone 6 Plus and at the mid-to-low end by Chinese players like Xiaomi.
In the second quarter of this year, Samsung's market share stood at 21.9 percent, down from 26.2 percent during the same period last year, according to Gartner. Apple's smartphone market share increased to 14.6 percent from 12.2 percent last year. Still, Samsung is the largest smartphone maker in the world.
Until Apple released its 5.5 inch iPhone 6 Plus last year, Samsung was the go-to choice for big displays. In a bid to lure users away from Apple's larger screen iPhones, Samsung released the 5.7 inch S6 Edge Plus and Note 5 last week.
