Make and receive unlimited calls with your mini-cell tower using AT&T Unlimited Microcell Calling. Start calls on your MicroCell and continue them on the go—without using your wireless plan minutes. MicroCell calling includes calls made within the U.S., Puerto Rico, the U.S. Virgin Islands, Guam, and the Northern Mariana Islands.
You can add Unlimited MicroCell Calling to most wireless plans. On shared plans, unlimited calling applies to all lines on the approved MicroCell user list. Heads up
: We don’t sell the MicroCell mini-cell tower anymore. But, if you already have one, we can still help you with your device. Don’t have an AT&T MicroCell? Try Wi-Fi Calling to talk and text in areas where it's hard for even a strong cell signal to reach. Learn more about Wi-Fi Calling
