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. We have been recommending WiFi-C (WiFi Calling) now as the preferred method for poor in-home coverage if your phone is capable of WiFi-C. If n

Cell Booster Pro stuck in a reboot loop

I received a Cell Booster Pro about 2 weeks ago. I've got it setup and connected, it registered and activated but I've never gotten it to work beyond that. It boots up and gets a GPS signal and then the status in the AT&T Cell Booster app will show it as initializing for about a minute or so and

I just want to say thank you from everyone that you have helped in this forum. As I understand it......your not an employee of ATT and you still spend your own time to help all these people out and that is a modern day miracle. It is hard to find people that will make way for the elderly and watch o

Arrogant terrible customer service

My phone has extremely poor signal in my area (I recently moved here). I contacted customer service on 10/11/2022 and was told that my issue would be resolved on 10/12/2022, if not then a cell booster would be sent to my address. However, after one week, no updates from AT&T at all nor any impro

Cell signal at home was excellent, now terrible

So, we just moved to a new house. It's way in the middle of nowhere.  When we first moved here, we had Verizon service.  I went on amazon and bought a cell booster.  I mounted a very high pole behind our house that more than clears the peak of the roof with an antenna on the top of i

3G was supposedly phasing out Feb 22, 2022 but my microcell's been working.....until today, 9/28/22

Hello! Not being tech savvy, please bear with me! My Cisco AT&T DPH151 Microcell stopped working today, 9/27/22. I read that AT&T was phasing out their 3G service on 2/22/22 but my Microcell was working fine until today. Was I just lucky, maybe the phase out didn't reach my area until

Only in Washington state?

Just talked to AT&T, and they stated that it’s only available in Washington state in store. They won’t ship any out, I’ll have to wait until it’s offered in my state which is Hawaii. Anyone else got that reply? Or got their device mailed to them?

land for tower

I have several acres of land that I would like to see if a cell tower could be built. I live in a rural area and the only service you can get is AT&T.  Yet the nearest tower is miles away so service isn't the best or doesn't work.  I would be grateful for any help you could give in th
