Jul 15, 2013, 09:30 ET from AT&T Inc.

DALLAS, July 15, 2013 /PRNewswire/ -- AT&T* has added three new Sonim rugged mobile devices to the AT&T Enhanced Push-to-Talk portfolio.

AT&T is now offering the Sonim XP1520 BOLT SL**, a rugged device designed to endure working in tougher environments within industries such as construction, transportation, manufacturing, and agriculture. The XP1520 BOLT SL can be dropped from six feet onto concrete, submerged in 6 feet of water for a period of 30 minutes and driven over with a pickup truck without missing a beat. This ultra-rugged device also comes with a comprehensive 3-year warranty that covers accidental damage and is equipped with a smaller camera.

In addition to the Sonim XP1520 BOLT SL, AT&T also offers:

Sonim XP5560 BOLT: A more traditional rugged device that is available in two different versions: one with a two megapixel built-in camera and another with no camera for use in high-security environments where cameras are prohibited. Both versions of the Sonim XP5560 BOLT come with a comprehensive 3-year warranty and are designed to survive even the most extreme set of circumstances on the job site.  With extended battery life, workers have up to 10 hours of Talk/Push-to-Talk time to maximize usage during multiple shifts.

Sonim XP5560 BOLT IS: This new device includes all the features of the standard XP5560 BOLT, but is certified Intrinsically Safe to support users in environments with flammable gases or dust. This capability enables workers in the most demanding energy, agriculture and manufacturing industry environments to now take advantage of AT&T Enhanced Push-to-Talk.

"We help businesses that need a fast and simple way of communicating with their workers," said Mike Troiano, Vice President, Advanced Mobility Solutions, AT&T Business Solutions. "AT&T Enhanced Push-to-Talk can conveniently connect people from one job site to another with a single touch of a button."

Key features of AT&T Enhanced Push-to-Talk include:

  • Larger contact lists and talk groups than competitive push-to-talk solutions
  • Ability to combine push-to-talk services and mobile applications, with help available from AT&T's team of mobility consulting and integration experts
  • Supervisory override that allows supervisors to communicate important time sensitive messages to their team
