How AT&T MicroCell works

What exactly is an AT&T MicroCell? How does it work?

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.

How do I buy a MicroCell if I don’t already have one?

AT&T has discontinued sales of new AT&T MicroCells. You can use Wi-Fi Calling to talk and text over an active Wi-Fi connection where it’s hard for a strong cellular signal to reach. Learn more about Wi-Fi Calling.

What are the broadband service requirements?

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.

Will the AT&T MicroCell cause interference with my Wi-Fi router?

No. Installed as recommended, there should not be interference between a Wi-Fi router and the AT&T MicroCell.

Can I use voicemail, text messaging, and data services on my wireless device when connected to my AT&T MicroCell?

Yes, your basic mobile handset services from AT&T are compatible with the AT&T MicroCell.

How many simultaneous calls or data sessions are possible with my AT&T MicroCell?

Your AT&T MicroCell supports up to four simultaneous sessions.

Can I use more than one AT&T MicroCell?

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.

Should I use my AT&T MicroCell instead of Wi-Fi for data?

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 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.

Compatible devices

What kind of handset will work with the AT&T MicroCell?

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.

Is the AT&T MicroCell compatible with devices like the Apple® iPad®, Kindle®, Nook®, Sony Reader®, or QUE®?

Not at this time. Wi-Fi provides optimal Internet access for these non-traditional wireless devices.

Billing / Account

How is usage billed when using the AT&T MicroCell?

Usage while connected to the AT&T MicroCell will count against your underlying wireless device rate plan.

Do I get detailed billing on calls made over my 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.

MicroCell Security / Permissions

Can I grant access to my AT&T MicroCell to other people's phones?

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.

Can I restrict access to my AT&T MicroCell? Is it secure?

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.

Using MicroCell

If I start a call on the AT&T MicroCell and leave my home, does the call continue uninterrupted? How is the call billed?

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.

Can I prevent the AT&T MicroCell from handing my call out to a cell tower?

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.

Is there any way to reduce the frequency of dropped calls when I walk around my home?

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

What should I do if I don’t need or want to use my AT&T MicroCell any longer?

To disconnect your AT&T MicroCell, unplug your MicroCell from the broadband router and the power source. Then, go to the Manage Settings tab on Sign in to your account and select Disconnect Your MicroCell Device. Please note that if your MicroCell isn’t connected and used for over one year, AT&T may deactivate your MicroCell. You can reactivate your MicroCell at any time.


Does AT&T MicroCell support E911?

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.

Is AT&T MicroCell service, including E911, available during power outages?

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.

Can I move my AT&T MicroCell and use it in another location?

Yes, you can if AT&T MicroCell is available in your area. Visit and select Check Availability to confirm. If available in your new location, sign in to your account to change your physical address.


What is the warranty on the AT&T MicroCell?

AT&T MicroCell has a 12-month limited warranty.

AT&T Wi-Fi Calling — An Alternative Solution

Use Wi-Fi Calling to talk and text over an active Wi-Fi connection. Wi-Fi Calling lets you talk and text from indoor locations where it's hard even for a strong cellular signal to reach.

*Wi-Fi is the optimal solution for home mobile data use, and doesn't count against your mobile data usage bucket. Visit for tips on setting up and using Wi-Fi. When using 3G data services through your MicroCell instead of Wi-Fi, standard data rates apply. MicroCell operation requires an AT&T 3G or 4G wireless device and Internet access service of at least 1.5Mbps downstream/256Kbps upstream. Device not compatible with satellite broadband services. Not intended for sale or use in homes or areas with strong wireless signal strength. Strong wireless signal strength may adversely affect MicroCell performance. For use with AT&T wireless devices only; not compatible with other wireless systems. Usage generated by MicroCell counts toward your wireless data usage plan limit and may be subject to applicable charges from your ISP. The maximum coverage of the AT&T MicroCell is approximately 40 feet. Actual coverage will be limited by the density of obstructions. Calls will transfer to a cell tower if you leave the MicroCell coverage area, but calls may drop if you return to the MicroCell coverage area. See AT&T MicroCell Service Agreement/Terms and Conditions for a full list of terms and conditions.
