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

MicroCell works with most broadband service providers, including AT&T broadband.

For best performance, minimum speeds of 1.5Mbps downstream and 256Kbps upstream are recommended.

Satellite and wireless broadband are not compatible.

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.
