AT&T is now running a new promotion, offering the Samsung Galaxy S4 Active and Galaxy Mega for free when signing a new two-year contract.

The Samsung Galaxy S4 Active is the rugged version of the company's flagship smartphone. It is designed to withstand harsher conditions and be more durable, targeting consumers with more active lifestyles. The Samsung Galaxy Mega, meanwhile, can hardly be called a phone considering its giant display. This device really blurs the line between a smartphone and a phone tablet, boasting a massive 6.3-inch screen that allows for better multitasking.

If you're unfamiliar with these two devices, check out their main specs below:
