AT&T 3G MicroCell acts like a mini cellular tower extending your wireless network in your home or small business for improved cellular performance.
If your AT&T 3G MicroCell wasn't activated at purchase, you can do it here.
First, select a wireless account type below - Personal if you pay for your own bill or Business if your company pays your wireless bill. You'll need your AT&T wireless phone number/user name and password.
If you haven't already set up an AT&T online wireless account, you can do so by selecting your account type below and following the on-screen prompts. Step-by-step instructions will guide you until you reach the confirmation screen message.
We make it easy to add or delete users, change the service
address if you move, or add a second MicroCell to your account.

*Wi-Fi is the optimal solution for home mobile data use, and doesn't count against your mobile data usage bucket. Visit www.att.com/wifiaccess for tips on setting up and using Wi-Fi. When using 3G data services through your 3G 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 1.5 Mbps downstream/256 Kbps 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 3G 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 3G 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 3G MicroCell Service Agreement/Terms and Conditions for a full list of terms and conditions.
