How AT&T MicroCell works
The AT&T MicroCell acts like a mini cell tower in your home and connects to your existing broadband Internet service. You receive improved cell signal performance for voice calls, texts, and cellular data applications like picture messaging and Web surfing. The signal range is approximately 40 feet from the base station (in all directions), or about 5,000 square feet.
The AT&T MicroCell works with any broadband service, except wireless and satellite broadband, as long as it supports the minimum broadband speeds of 1.5Mbps downstream and 256Kbps upstream. It does not replace your existing broadband service.
No. Installed as recommended, there should not be interference between a Wi-Fi router and the AT&T MicroCell.
Yes, you will be able to surf the Web from your computer while making a call.
Yes, your basic mobile handset services from AT&T are compatible with the AT&T MicroCell.
Your AT&T MicroCell supports up to four simultaneous sessions.
Yes, they may be used in different locations or within the same location if 5,000 square feet of coverage is not sufficient. The devices should be placed at least 40 feet apart. If they are too close together, interference between the two devices could cause calls to drop.
No. Whenever available, Wi-Fi should be used for data applications like streaming video, downloading files, or surfing the Web. Wi-Fi is the optimal solution for mobile data use, and doesn't count against your AT&T wireless rate plan. Visit www.att.com/wifiaccess for tips on setting up and using Wi-Fi. When using 3G data services through your AT&T MicroCell instead of Wi-Fi, standard data rates apply.
Any 3G or 4G-capable handset with AT&T wireless service will work on an AT&T MicroCell. You can't activate an AT&T MicroCell with a GoPhone®, but GoPhone users can be added as Approved Users. Handsets with other carriers' services will not work with MicroCell.
Not at this time. Wi-Fi provides optimal Internet access for these non-traditional wireless devices.
Billing / Account
Usage while connected to the AT&T MicroCell will count against your underlying wireless device rate plan. There is an optional Unlimited MicroCell Calling feature which will provide you unlimited voice minutes while connected to an AT&T MicroCell.
If you currently have call detail billing with your rate plan, all calls, including calls made while connected to an AT&T MicroCell, will continue to have call detail available as usual.
Certain rebates may be available with subscription to additional features or services, including the Unlimited MicroCell Calling feature. Forms can be printed from the link below.
Please be sure to select the correct form based on the date range and the feature or services added:
Purchase Date: 11/8/13 - 7/11/14
$100 Mail-In Rebate - with subscription to the Unlimited MicroCell Calling feature
MicroCell Security / Permissions
You may grant access to other 3G or 4G-capable handsets with AT&T wireless service, up to a total of 15 lines. Handsets with other carriers' services will not work with AT&T MicroCell.
Yes, you can restrict access to your AT&T MicroCell. Only those added by you to the Approved User list will have access to your AT&T MicroCell. All others are restricted.
No. Calls will not hand over between two AT&T MicroCell devices.
Yes, calls seamlessly transfer from the AT&T MicroCell to the strongest AT&T cell tower signal. Billing will continue based on the initial connection being placed on the AT&T MicroCell. If the call is dropped and redialed on the cellular network, then the call is billed against your wireless device's AT&T rate plan.
No. Calls initiated on a cell tower do not transfer to the AT&T MicroCell.
Yes, you can manage automatic hand-out from the AT&T MicroCell to an AT&T cell tower. See how to manage your AT&T MicroCell for details. Once you have disabled the hand out, if you begin a call on your AT&T MicroCell, you will need to stay within range of the AT&T MicroCell in order to avoid a dropped call.
See "Can I prevent the AT&T MicroCell from handing my call out to a cell tower?" Preventing the hand-out of a call from the AT&T MicroCell to a weak wireless signal can reduce dropped calls
Yes, E911 services are supported. You must keep the address where the AT&T MicroCell is physically located up to date in order to ensure the proper location is available to emergency personnel.
No. AT&T MicroCell service is not available when either electrical service or your broadband service is unavailable. In the event of a service disruption, you will not be able to access E911 service using your wireless device unless you have service on the AT&T wireless network. The AT&T MicroCell unit includes a GPS device that enables the unit to identify its location. The AT&T MicroCell will not work until it has identified its location. If the AT&T MicroCell is moved to a new location, it is important that instructions for updating the device location are followed to enable E911 service to function properly.
Yes, your AT&T MicroCell can be moved to another location provided it is within the AT&T wireless authorized service area. A device move requires an update to your location address in your AT&T MicroCell account profile for the device to function and for 911 purposes. See how to manage your AT&T MicroCell for details on updating the physical location of the device.

Install device in a sheltered location with a temperature range of 0 degrees to 38 degrees Celsius (32 degrees to 100 degrees Fahrenheit).
Installing near a window is strongly recommended to ensure access to Global Positioning System (GPS). A GPS link is needed to verify the device location during initial startup.
MicroCell unit may be moved if new location is within an AT&T authorized service area and properly registered online.
Calls transfer out, but do not transfer in. Calls transfer from the AT&T MicroCell to the strongest available AT&T tower signal. Calls connected on the cell tower do not transfer to the MicroCell.
Firewall Specifications System Administrators (Business Customers): Installing the MicroCell behind a firewall, or behind a router with firewall capabilities, requires the following ports be opened to prevent the firewall from blocking communication with the network. This type of installation is typically found in corporate environments.
123/UDP: NTP timing (NTP traffic)
443/TCP: Https over TLS/SSL for provisioning and management traffic
4500/UDP: IPSec NAT Traversal (for all signaling, data, voice traffic)
500/UDP: IPSec Phase 1 prior to NAT detection (after NAT detection, 4500/UDP is used)
4500/UDP: After NAT detection, 4500/UDP is used
