SAMSUNG GALAXY S4 ACTIVE i537 BLUE 4G LTE AT&T GSM UNLOCKED CELL PHONES - FACTORY REFURBISHED

Enjoy the freedom of being able to take your smartphone almost anywhere with the Samsung Galaxy S4 Active for AT&T. It's designed to enhance your smartphone experience as you explore environments from the most rugged mountain trails and roughest rivers to the everyday thrills and spills of commuting.

The fully sealed design keeps dust particles out and protects against water damage for up to 30 minutes of submergence at a depth of one meter. Equipped with a water-resistant earphone jack, the Galaxy S4 Active frees you to use earphones in more adventurous conditions, in the same way you've used them in normal ones. And the 5-inch display is made with tough, scratch-resistant Gorilla Glass 2, so you can toss it in your gym or camping bag without worrying if it'll get wet or dirty.

The advanced 8-megapixel rear camera is complemented by a front-facing 2-megapixel camera for video chats. Whether capturing every moment of a wild rafting trip or taking a great underwater photo in the pool, the Galaxy S4 Active?s unique construction enables you to capture amazing moments previously impossible using a normal smartphone.

Running the Android 4.2 (Jelly Bean) operating system, the Galaxy S4 Active is powered by a 1.9 GHz quad-core processor. It features 16 GB of internal storage, which can be expanded using optional microSD memory cards up to 64 GB. Its 2600 mAh battery provides up to 17 hours of talk time and 13 days (312 hours) of standby time.

Bring People Together

More than just a personal device, the Galaxy S4 Active makes the most of your relationships and enables you to easily share and experience many of life's pleasures together with family and friends, wherever you are. With the Group Play function, you can enjoy music, photos, documents, and games with those around you without even requiring a Wi-Fi or cellular signal. You'll be able to connect directly to other Galaxy users instantly. For example, the Share Music option enables you to have the same song playing on multiple phones in sync to create the best party atmosphere.

Take it at Your Own Pace

Offering a number of features for first-time smartphone owners as well as those switching from another operating system, the Galaxy S4 Active has a streamlined start-up wizard so you can begin using the device faster and learn about its unique features from the start.

Originally introduced with the Galaxy S3, Easy Mode has been enhanced by simplifying the home screen layout, camera, calendar, messaging and the internet browser to make the settings menu easy to navigate. Once you're more comfortable with the Galaxy S4 Active, you can switch back to the standard home screen interface.

The Smart Switch PC application enables you to transfer contacts, messages, photos, music, calendar notifications and more from another phone to the Galaxy S4 Active. Smart Switch can identify favorite applications and recommend the same or similar applications within Google Play.

Protect Your Information

Not only ideal for personal use, the Galaxy S4 Active is also a SAFE-designated device, which means it has additional security features to safe-guard sensitive data and communications. The Galaxy S4 Active is the first Samsung device to include Samsung's KNOX solution, which provides comprehensive mobile security at the hardware level and enhanced personal privacy for individuals at the software level. It delivers industry-leading mobile security for companies with stringent security requirements, and allows IT managers to access and manage the passcode-protected work information without disturbing the content within an individual's personal space (including photos, emails, music files and social network data).

AT&T boasts the largest 4G mobile broadband network in the United States, covering more than 292 million people with a combination of two layers of 4G technology: the 4G LTE (Long Term Evolution) network and an older technology called HSPA+ that delivers near-4G speeds. AT&T's 4G LTE network is currently live in 261 markets across the U.S. (as of May, 2013) with more markets continually being added. AT&T expects to cover 300 million people with its 4G LTE network by the end of 2014.

With 4G LTE technology, you'll get mobile Internet speeds up to 10 times faster than 3G, enabling you to upload a photo in 6 seconds, download a song in 4 seconds, and download HD movies in minutes and apps almost instantly. You can expect average download data rates of 13 megabits per second (Mbps) and 6 Mbps for uploads in real-world, loaded network environments.

If you are not in an area served by 4G LTE, you'll be able to connect to AT&T's HSPA+ enhanced backhaul network, which delivers speeds up to 4x faster than AT&T's HSPA 3G network. With the combination of 4G LTE and HSPA+, you'll enjoy higher data speed averages than other networks.

In areas where either AT&T's 3G or 4G network is not available, you'll continue to receive service on the AT&T EDGE network, which offers availability in more than 13,000 US cities and along some 40,000 miles of major highways.
