AT&T MicroCell

AT&T MicroCell - enhanced voice coverage for your office.

Enhanced voice coverage for your office.


A competitive advantage

When conducting business on your smartphone, you want your signal to be strong and clear. AT&T MicroCell™ is a small, cellular base station that acts like a mini cell tower to provide an enhanced cellular signal and voice coverage for your office. It connects to the AT&T network using your existing office broadband service and supports up to four simultaneous users.

Clear coverage throughout the office

AT&T MicroCell gives you improved in-office coverage for simultaneous voice and data—for up to 5,000 square feet. Employees can rely on a clearer, stronger signal for client calls, data downloads, and more.* Help boost coverage at your remote locations and home offices by adding additional AT&T MicroCell devices.

Manage expenses easily

The optional unlimited calling feature gives you unlimited nationwide anytime minutes for incoming or outgoing voice calls originating on the MicroCell device. Enjoy unlimited voice usage on the MicroCell device while in the office for domestic calls—without using existing plan minutes.


Employees and clients alike can enjoy enhanced coverage, because you choose which AT&T numbers use the AT&T MicroCell device. Easily add up to 15 authorized users and manage device settings through the AT&T MicroCell web portal.
