AT&T 3G MicroCell™

Get more done every day with improved in-office coverage.


A competitive advantage

Now you can respond more quickly—and reliably—to customers and associates using an AT&T 3G MicroCell™. This small, cellular base station acts like a mini cell tower that provides an enhanced cellular signal for 3G devices. It connects to AT&T's network using your existing office broadband Internet service and supports up to four simultaneous users.

Clear coverage throughout the office

The AT&T 3G MicroCell gives you improved in-office coverage for simultaneous voice and data—up to 5000 square feet. Employees using AT&T’s industry-leading 3G devices can rely on a clearer, stronger signal for client calls, downloading data and more.* Plus, for your remote locations and home offices, you can add additional AT&T 3G MicroCells and help boost your coverage.

Manage expenses easily

The optional AT&T Unlimited MicroCell Calling feature gives you unlimited, nationwide anytime minutes for incoming or outgoing calls while operating from the 3G MicroCell. You and your employees can enjoy unlimited use of the 3G MicroCell while in the office for domestic calls—without touching existing plan minutes.

Talk and go

The AT&T 3G MicroCell gives you a seamless call hand-over, meaning a call you start with MicroCell coverage can continue without interruption when you leave the office. If you’ve chosen the optional Unlimited MicroCell Calling feature, unlimited calling continues until the end of the current call.


Employees and important clients alike can enjoy enhanced 3G coverage, because you choose which AT&T numbers can use the AT&T 3G MicroCell. Once you’ve registered online, it’s easy to add or delete up to 10 authorized users and manage device settings.
