The Cell Booster Technical Guide is now available

The Cell Booster Technical Guide is now available thru my sig line. AT&T reviewed and approved it pretty much as is. The formatting appears to have changed a bit during the transfer so there may be an inconsistency in the TOC (Table of Contents) but you'll figure it out 😁. The Guide will loo

Microcell Technical Guide

Hello. This is OttoPylot. I created a MicroCell Technical Guide that may be helpful to you. I try to keep my guide as current as possible given the ever-changing nature of ISP’s, equipment, customer’s needs/expectations etc. It is meant as a supplement to AT&T’s Customer Support but is not officiall

Cellular Booster Guide

The MicroCell was discontinued as of the end of 2017, as most of you already know. AT&T will still support the MicroCell but for how long is anybody's guess.

MicroCell Service To Be Discontinued

Feb. 2022 is the final date for the complete shutdown of AT&T's 3G service. Some service areas will start very soon to begin shutting down 3G devices. The MicroCell is a 3G device so if you all of a sudden lose connectivity to the AT&T Mobility Servers, that could be why. I've been asking AT

ATT Replacement for 3G microcell, is it truly a cell booster now versus the old FEMTOCell setup?

I am wondering if this new "booster" is in fact just a cell phone booster  versus the way the 3g Microcell unit worked.
