    Samsung 4G LTE Network Extender is rated 3.9 out of 5 by 48.
    Rated 5 out of 5 by from Worth the upgrade from 3G extender I bought this a week ago and couldn't be happier with my decision to upgrade from the 3G Network Extender. Living in Sugar Land, TX, I could not figure out why I wasn't getting great service in the house. After some thought, I think it had to do with the fact my house has a radiant barrier on the roof. Setup was a snap. The only issue I experienced was that I had to make a call to Verizon to activate the extender. Because I had the 3G extender on my account, the system wouldn't allow the 4G extender to activate. After a quick 4 minute call to Verizon, problem solved. The unit took about 30 minutes to start up and lock onto satellites. The coverage around the house is FAR superior to my old 3G extender and I couldn't be happier I upgraded. I am getting full bars through the entire house (~4,000 sq ft). I have a Galaxy S7 Edge, Pixel XL, iPhone 7 and all are working perfectly (verified using #48). Hand off when leaving the house is seamless unlike the 3G extender where calls were constantly dropped when the device disconnected from the extender. The only gripe I have is that is an open extender unlike the 3G extender. What I mean is that anyone can access the extender and I cannot lock out neighbors or visitors. I don't think this is a major issue as the coverage for the extender is 7500 sq. ft. I would highly recommend getting this 4G extender if you are having any service issues in your home.

    Rated 5 out of 5 by from Compared to the older model - The 4G LTE is so much better We have been using the older version of the Network Extenders for several years now. They work most of the time but were inconsistent with connecting to your phone and had that annoying two-tone beep when you placed or received a call. Well, with the new 4G LTE Extender, things changed. The one we just purchased is user customizable. This allowed me to set a static IP and change the output wattage. Also, it just connects up on its own, every single time! There are no two-tone beeps. I have yet to miss a call when connected to this thing. We are so happy with it, we are replacing all our older extenders with these!!

    Rated 5 out of 5 by from Works exactly how I wanted it to I just received the 4G Extender today. It took about 15 minutes to get configured. My Samsung S7 went from 1-2 bars to a consistent 5 bars. My calls have been clear with no drops. My download speeds are in the 70-75mps range (wifi 5ghz around 50mps) as long as it continues to do what it is currently doing, I will be happy.

    Rated 5 out of 5 by from Works Great Many people, including some of the tech support folks at Verizon, will say this device isn't worth it if your device supports Wi-Fi calling. I have an iPhone 7 and live in a great coverage area. However, I live in a very densely populated downtown setting in a high rise building. Sometimes my signal would be low and I found that Wi-Fi calling wasn't always reliable as the iPhone would see just enough signal from the Verizon tower that it would keep flipping back and forth. This caused missed calls, calls being sent straight to voicemail, etc. After installing this network extender I now have 5 full bars of service in my house. It works perfectly. I would highly recommend it. The only drawback is that it works in open mode only, meaning you can't restrict this device to a specific set of devices. Any Verizon 4G LTE device in range will pick up signal from this device until it maxes out on connections.

    Rated 5 out of 5 by from It works! We have less than 1 bar of service at our house and no service inside the house. I just bought 4g phones and set this extender up today, and now we get 4 bars inside and outside the house. The set-up was super easy; we put the antennae in a high window and let the device do its magic. No problem.....and done in less than the 1/2 hour the guide set as a minimum. As a matter of fact, the activation of the phones was MUCH more of a hassle. Now we're only 2 hours in, but so far so good.
