We got our device today and tried to connect. The Signal Supervisor app wouldn't let me register our account because I didn't receive the security code sent via SMS. I ended up calling support and the very helpful lady who answered the call (yes, real person) told me to uninstall the app, reinstall it and try again. Also, she said if that doesn't work, I can sign up through the website. The app still didn't send me a code so I went online and signed up via email. It worked and when I went back to the app on my phone my account was in it and it started working fine. The parent company is HiBoost. Although there aren't many reviews for this device, HiBoost has a ton of good reviews. Installing an external antenna was a hassle, but we finally have something to live with, but it looks like I'm only going to get a few bars anyway. But I've been lucky enough to get 1 bar inside before, so I was hoping this would at least allow me to make and receive calls without constant disconnects. We had an outdoor antenna outside the garage and decided to place it upstairs in the attic. a garage that would place it higher than we placed it outside. As soon as it connected, my phone immediately went to 4 bars! The frequency in the Network Cell app showed -65dBm where it was -111dBm before we started and 108dBm outside the garage. It was a definite step up, so we decided to install it in the attic. We have only connected 1 indoor antenna so far but I have 4 strips throughout the house so it may not be possible to install both antennas. We only have a 1450sf ranch, maybe that's why. In any case, we are very satisfied with this device and would definitely recommend it. A bit pricey but you get what you paid for.
