Cannot register a third-party cell phone signal booster with AT&T

We purchased a third-party cellular signal booster to support a medical alert device for my father.  After setting up the booster to confirm it will generate a boosted signal strong enough for the device, I went to register the device (per FCC regulations) with AT&T. The only instructions I could find required me to install AT&Ts booster app on my phone. After doing that, the app asked for the device's serial number. When I typed it in (several times) the app returned 'invalid serial number'. I then learned the app is to support AT&T's own cell signal booster. Online, I found a listing of devices that can be registered with AT&T, but this brand (PhoneTone or PhoneToneTech) and model (AN-L65AV) aren't options. How can a person register a device with the FCC through AT&T, as instructed and expected, if there are no means or tools available to do that?

AT&T's 'cellular booster' is not a booster. It is in MicroCell for LTE.

AT&T's booster / MicroCell requires a wired home internet service in order to function to create a network where there is none. 

If you have indeed purchased a booster, all it requires is electricity in order to amplify cellular signal.  There is no app for a true booster. 

There must be some signal in order to amplify. If you have no signal at all you do need a device connected to home internet like AT&T's device. 

It comes with a label as here.

And the form

We'll be happy to clarify what's going on with this @Mark_8530.


In order to proceed, you'll need to have a cell booster that's compatible with our network. You can order ours online or purchase it at an AT&T store


Please let us know if you have any additional questions or concerns. Thank you for reaching out to our AT&T Community.
