Find out how to reactivate your MicroCell if it was disconnected for inactivity.

Quick AnswerQUICK TIP

Before reconnecting your AT&T MicroCell®, check if your mobile devices are compatible with Wi-Fi Calling. If they are, you may not have to use MicroCell in your home.

With Wi-Fi Calling, you can talk and text using your active Wi-Fi® connection instead of your MicroCell. Learn how to switch from MicroCell to Wi-Fi Calling.

Getting reconnected

Heads up: We’ll stop providing MicroCell service in February 2022. Between now and then, we’ll deactivate MicroCells that haven’t been used in three months.

To get the best results, be sure you have high-speed internet, and install your Microcell:
  • On the first floor or above basement level, and not in a closet
  • Next to a window so the signal has a clear, unobstructed path to the sky
  • At least one foot away from other wireless broadcasting devices
  • When the weather is clear (no clouds or rain)

How to reconnect your MicroCell

  1. Connect one end of the Ethernet cable to the Ethernet port on your MicroCell and the other end to your router or gateway.
  2. Plug your MicroCell into a power outlet with the AC power adapter.
    • The power light on the front of the device will light up right away. It can take up to a minute for the Ethernet light to stop flashing. Within a few minutes, other lights will flash as the MicroCell locates a GPS signal and updates its software.
    • It can take up to 90 minutes for your MicroCell to fully activate, and it may restart. You’ll know it’s ready to go when the network light stops flashing.
  3. Try making a call once your wireless device shows AT&T MicroCell or AT&T M-Cell instead of AT&T as the network provider.

MicroCell deactivation text message

You may get a text that we’re deactivating your MicroCell. We do this when our records show your MicroCell hasn’t logged any talk or data use in at least three months.

Our records may show an unused MicroCell if you have:
  • An old MicroCell that you unplugged and no longer use 
  • A MicroCell that wasn’t fully active
  • A working MicroCell with an extra unused one linked to your account

If you got a text and don’t want your MicroCell deactivated, just use it in the next 30 days. We’ll remove your MicroCell from the deactivation list.

If you’re OK with having it deactivated, you don’t have to do anything. We’ll do it for you.
