AT&T Cell Booster

Received the cell booster unsolicited (and at no charge) from AT&T. Tried to connect. Never did work when connected to router or directly to modem. Total waste of time. Don’t bother. Will continue to have a landline since we are lucky to have 1 bar with AT&T cell. 🤮

Easy setup - use QR code on front of the device - it will make setup a breeze. I think I’ll get one for home, too.

Will not even show any status indicators for my device anymore …. Device status just continues to say not available. My 4 g won’t connect with even rebooting uggg

I went from 1-bar to 4-bars, ground floor condo in Naples FL. Cell signal & WiFi assist had given very poor results. You must have a) GPS signal that pinpoints your location b) port on your router c) ATT login account & patience. The GPS antenna stuck on the window is necessary for setup - and then can be stored. The GPS identified that the device location matched my account location; and then an hour later everything was working very well. The back office work was done with no input from me. I am super happy with it and very pleased that I went to the effort.

I ordered the AT&T cell booster despite all the poor reviews because I work from home and can’t live without cell service. In theory this app should make setting up the device easy; in practice I couldn’t ever even get my device registered despite multiple attempts and a solid background in consumer tech. The AT&T support rep said things like, “there are a lot of gray areas with setup,” and also said the tech support team has passed along customer frustration with this app. So here’s an idea, AT&T: If it’s so bad that even your own people know it’s bad, just fix it. It’s crap.

Set up was straightforward, but it wouldn’t connect to my phone. Before I called tech center, I did all the usual reboot this and that stuff, to no avail. Talked to tech support. About the only thing I could understand was the 2000 times the “service professional” said “We’re sorry”. They finally told me I had to contact my ISP, because there may be restrictions on my Wi-Fi router. Seems legit, except I have my own router, and there ain’t no restrictions. So I rebooted everything again, and voilà! 4 bars of 4G LTE instead of 1 bar of 5G! Great! Then I left the house for a few hours, and, whah-whah-whah, won’t connect again. My old 3G AT&T Microcell worked flawlessly for a decade, and the app was easy. Walk in the house, it automatically connected. This one, not so much. Every time I open the app, it makes mean completely log in, and the CellBoost Status page just says I have all white lights. I’m going 2-stars instead of 1, because I have this little guy in the back of my brain telling me I did something wrong. Will update if that proves to be the case.

Cell Booster is amazing, but the app has a lot to be desired. Very unstable, it works when it wants to. Totally undependable.

First of all, I need to say that I purchased this for use around my home which at best I would get one bar. Most of the time I had no bars. This was my last ditch effort to get a decent cell phone signal in the house, and hopefully do better than Wi-Fi calling. My biggest challenge with Wi-Fi calling is that it would flip-flop between cell and Wi-Fi and drop my call mid conversation. We tried multiple carriers, like T-Mobile, Verizon, and AT&T, and all have the same result. Installation was a snap. I downloaded the app. I then scan the QR code on the front of the device and follow the directions. Once I connected to the Internet and had the GPS connected to the window, I was able to get a decent GPS signal and the device registered and was connected. A few minutes later, AT&T sent me a notification that the booster was registered and online and from that point forward I’ve had 4 full bars of connectivity. So my experience is definitely different than most. Others reported here, so obviously something is very different in the conditions of their environment versus mine. Bottom line this was a pretty decent experience and very pleased with the wireless signal. I made a few calls, and they sounded crystal clear. I’m a happy guy.

Worked just fine until I had to login again. Wants new setup but will not allow because existing account.

The Cell Booster was a snap to set up. Yes, I had a problem at first too, but it was because my router needed to have some settings changed to permit the cell booster to get through to the internet. The tech support page on at&t’s website about firewall and router is actually very helpful and tells you precisely what to do. Plus I have gone from 1 bar to full service. Anyway the app is fine insofar as it goes. My biggest complaint about it is that it does not support FaceID and there’s a bug with passwords stored on the iPhone keychain. Seems like a simple fix.
