SureCall Flare 3.0 Cell Phone Signal Booster for Home & Office up to 3500 sq ft, Boosts 5G/4G LTE, Yagi Outdoor Antenna, Multi-User, Verizon AT&T Sprint T-Mobile, FCC Approved, USA Company

Why did you pick this product vs others?: I bought this for my cabin in NH. We get a single bar as measured by our cell phones. We could make and get calls, but audio quality poor and web browsing was painful, with many pages freezing before displaying. I didn't expect miracles, but with this product I can at least now surf the web without swearing and can reliably make and take phone calls. It was pretty easy to install (I also bought a pole to mount on the wall to extend above the apex of my roof). It was easy to install if you are moderately handy with common tools and can climb a ladder. To orient it properly, I downloaded the free OpenSignal app. They have a simple compass that points to the closest cell tower for your service provider. Before making the installation permanent, I used the SureCall app to measure signal strength, adjusting the antenna 5-10 degrees +/-. They provide 50' of coax, which was perfect for me, but for you will depend on the dimensions of your home or apartment. If you need more, you can get an extension coax. They say that the vertical distance between antenna and modem should be at least 25'. Mine was about 18'-20' and the app reported it was "good". I can imagine apartment dwellers may find it difficult to get this much vertical distance.

Having recently come to a very remote area of Northern Wisconsin from the "big city", I was losing my mind with no cable or internet and only spotty cellular data access. My Verizon coverage was zilch in the house and between slim and none outdoors unless I was standing in just the right spot, on one leg, with the planets aligned (even then, slim was VERY slim, if any). My mom's AT&T service was solid outdoors, decent at one end of our big old 2-story farmhouse, and spotty at the other end. So I decided to try a booster. After reading reviews and learning more about "gain" and what the "dB" measures really mean than I thought I'd ever need or want to know, I purchased the SureCall Flare 3.0. First, you need to know that my Verizon coverage remains abysmal. When they say this product boosts a signal but cannot create signal from nothing, they were just being 100% honest. Make sure you run a signal test on your phone or can at least make a phone call with your particular carrier outside before investing in this or any product. I did get the Yagi directional antenna (not the omni), but aside from Verizon installing a tower right in my backyard, I don't think any product would get me out of this dead zone. So why did I give this product 5 stars? It did just what it was supposed to for my mom's AT&T coverage and was quite easy to install, even for a person with minimal tech savvy . We now have a robust AT&T signal throughout the house, texts are sent and received quickly, websites load in a blink, and we've said goodbye to interrupted streaming and the dreaded buffering. This also means mom can launch a stronger hotspot which has made my life better, too. Other tips: If you only receive a one or two-page manual in the box, I suggest you read through the full PDF manual on SureCall's website. They offer a much better explanation of the LED lights on the booster and what they really mean. Just the green light is optimal / best function, yellow flashing lights on either side mean it is working, and working ok, just introducing some additional system checks. Any red lights are the ones that require further action. This was confusing in the short-form manual I received in the box. SureCall also has useful videos. For mounting the outside antenna - think about where you're most likely to install this and order or get a mounting pole that is not included. Yes, you do get two u-bolt clamps and a bracket in the box, but if I hadn't repurposed an old satellite dish pole mount, I would have had to order or get a pole. I also had success mounting the antenna roughly 12 feet off the ground on the side of the house as I didn't have a safe way of getting up on our steep, two-story roof on my own.

Only covers about 13'x13' at full strength from the internal antenna. So about 1 bedroom. Beyond that I completely lose signal if I go about 10' more outside of that. Other than that I don't have the antenna mounted where I want yet but in it's temp home I have 4-5 bars on TMobile, 2-3 on AT&T but I am pointing at the T-Mobile tower because it's what I mainly use and it's faster. I had no bars at all on TMobile, sometimes I would need to drive miles before getting a signal so that's pretty damn impressive. AT&T had 1-3 bars depending on who's phone, time of day, etc, but the speeds always sucked. I have the external about 12' up but I plan to move it to the peak of the house soon. The cable that came with it is maxed out, so 30' or wherever it is in case someone was wondering about the separation. Basically opposite ends of this tiny house. The best speeds I got so far were around 5mb. Keep in mind these boosters aren't really for data speeds. If you want faster internet then invest in a good modem like a peplink or one of the other guys that cost $400-$1400, you will also need a 2x2 MIMO or 4x4 MIMO Antenna. At least you will have an idea where your tower is if you already purchased the booster and if you want both like I do (Cell and Data for home internet) then you will still need both and different antennas. I'm going to open up the base station and see if I can connect a different antenna for internal. If I can connect an antenna then I can just drill a hole in the plastic to mount it and it will look factory-ish. The house its used in is tiny, I was shocked it didn't even cover the first floor. It's basically just one room coverage so I'm unsure where this coverage quote is coming from in the item description and pictures. I'm just happy it actually works in contrast to nothing at all. Even if I do have to keep my phone in one room in the house. At least I'm not missing a bunch of calls and texts. Side note, yes I have RCS texts and calling over WiFi. However the only internet is DSL and it's on the edge of service so it's 10 down 1 up, barely 1 most times. Yes that is the real speeds. Anyway if you have an Android phone and if your internet isn't good enough, your RCS and VOLTE will fail. This was true for these phones using the following services. These are also some of the devices I have been testing with. T-Mobile Mint Verizon Google Fi Google Voice - Pixel 6 Pixel 4a 5g Xiaomi 12T Xiaomi 8 The house is less than 25'x25'. So the booster covers about 25% of one floor, kind of sad really

Installation is straightforward, but can be a bit tedious to find the right cell tower information, location, etc. and get the antenna set up / pointed correctly. Once in place, the app provides good information as well. Users should be aware that they may need to cycle through airplane mode to get their device to connect through the booster, depending on their specific coverage situation. Customer service / technical support at SureCall was super!
