- 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

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.

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.

I'm an engineer. I did everything that the manual said. NO matter how far the separation the yellow light was always on...I would say easily 50 to 60 feet away. One end of the house was the antenna and on the far end of the house with a second cable went well into the garage At least 15 feet vertical separation followed by 50 feet horizontal separation. Yellow light always stayed on. Ran speed tests. Never better and sometimes worse. Had to lay the phone on the antenna to maybe get some improvement...could not tell. The app shows green, but that according to AI is the bluetooth signal, not the cell tower...dishonest. Great, phone is connected, but get absolutely no improvement. Tested in good and bad weather (I said I was an engineer). Tried aluminum foil at the antennae and at the base unit to block other signals...often turned red signal in that case. Bottom line - no improvement. Gets into bands too (another dishonesty here) in that my carrier is verizon and there apparently is no way to keep it on the Verizon band so the phones will just bounce around incompatible with this device. Long story and I am too frustrated to do anything else. Bottom line - NO improvement in download and upload, often worse. Get 10 inches away from the base unit and my phone is back to the state it is in without this at all. Something is wrong with this product and the way it is being implemented and marketed. I spent ALOT of hours trying to make it work. It does not and will not work in my house. I have Verizon and a Samsung phone. I believe this product (not absolutely) that this is incompatible with these two products. I'll save the AI chat on this which provided some additional insights why it was not working.

Do you have crummy service and are desperate for improvement? Do you have patience and problem solving abilities? Have you been scouring the internet for reviews on cell boosters to decide which to blow hundreds of dollars on? Well I did and I got it right on the first purchase in my small A-frame home in rural Alaska, here’s what I can share: Get the Flare 3.0 with Yagi directional antennae (the pointy one). Decide how you’re going to mount this antennae, we did galvanized steel pipe with an elbow joint so it’s super easy to rotate the antennae for fine tuning. Also mount it somewhere that it’s not a huge pain to rotate this thing, you’ll be doing it A LOT in the beginning. We mounted ours outside an upstairs window, within reach from inside house. Hunt down your carriers nearest cell towers. Cellreception.com (other sites exist too, give it a google) has good maps you can then pinpoint over in google maps. Google maps usually has a little blue triangle that tells you which direction your phone is pointing - this is huge to make sure your antennae is pointing right at the cell tower. Line up the direction your phone and the antennae are pointing. Try a couple different towers, sometimes based on topography/tower strength a slightly farther tower could be better. Download the OpenSignal app and use it A LOT. Run the speed test in areas that do have cell service to help you hone in on what to expect. Run the test all over the house, the yard, etc. Goal is to find part of your house/yard that has a bit of service, set the antennae there and point it STRAIGHT at the carrier’s tower. Connect the coax cable and power cord to the Flare device. Now you’ll probably end up with the yellow flashing lights of oscillation death. You’ll learn to understand, accept and befriend this flashing yellow punk. Oscillation happens when the signals put off from antennae and indoor device interfere (like when you bring microphone too close to an amplifier and get that terrible feedback noise, same concept). The manual will tell you to eternally move your indoor device (the Flare) farther away. Before you know it you’ll be three towns over and the light will still be flashing “too close”. Here’s some solutions to oscillation: - Move the devices further apart- vertical vs horizontal distance have greatly different effects. Moving one or both devices away from each other vertically works better than horizontally - Place indoor device so antennae direction is exactly opposite, so Flare is “behind” yagi antennae (but also hopefully below and 20ish feet away) - Put something metal between antennae and indoor device - careful here because you don’t want that metal to also block the indoor device from sending signals to your phone! I used a cast iron pan for a while when troubleshooting and it worked well - Finally the best advice we found, place the Flare directly blow the Yagi antennae. If you think of how signal would wave out of an antennae, the space right beneath it gets almost no waves, in this situation ground zero is a good place to be. We now have significantly better service after lots of tweaking our setup. We still have the flashy yellow, but it’s a slow flash. The goal is to get away from the red+yellow flash of death (means oscillation so severe the system shuts off). Yellow means there is oscillation and the more rapid the flashing the worse it is. You can get good service on slow flash yellow, use the app and move indoor device around (with tips above) to fine tune this for your home. Good luck and god speed friends. Make a plan for the places you’ll try placing the antennae/indoor device and have patience. Having better cell service is magical, but it comes with lllllots of troubleshooting and trying new tactics. Keep an eye on your 30 day window and when in doubt, send it back for a replacement.

Purchased the SureCall Flare 3.0 Cell Phone Signal Booster in March 2025. Took me a few weeks to get around to installing it (running the cables from the outside antenna to the booster inside the house was quite a chore). Once I got everything installed and got it up and running, it was working as advertised. Had to be pretty close to the booster to get the most benefit, but it worked nonetheless. However, the booster stopped receiving power after a couple of days. Had to return it (at my own expense) to get a replacement. Took a few weeks, but got the replacement and I installed the new booster right away. Once again, it worked as expected for a few weeks, but....once AGAIN, it stopped receiving power. There is nothing abnormal about where I have this device plugged in. I have it plugged into a power strip along with a few other devices to protect against power surges and everything else works just fine. In fact, everything in the house that's plugged in works just fine, except this cell booster device. I do not want to spend money yet again, to send this device back for replacement just to have it die again. I don't know if this device is just poorly made or if I just have the worst luck known to mankind, but in either case, I cannot recommend this product. **UPDATE: 12/15/2025** I have updated this from 1 to 3 stars because the customer service was very good. "Kevin" at SureCall contacted me in September and offered to send me another booster device, while also paying for the return of the 2nd one that stopped working. The return was made and the new one received and installed. So far so good on booster number 3 (maybe 3rd times a charm?), but time will tell. I would have given it even more stars but the range on this booster is not great. It works fine for my purposes because I mostly use it to boost my cell service when I need it for a mobile hotspot in the event my internet is down or unreliable (frequent remote worker). And the booster sits on my home office desk very close to my mobile phone. So literally within 2-3 feet. But if I step away with my phone much further than that, I seem to lose any benefit from the booster.

⭐️⭐️⭐️⭐️⭐️ Huge Improvement — 1 Bar to 4 Bars LTE! I live in a rural area and usually only get one bar of LTE, but this SureCall Flare 3.0 Cell Phone Signal Booster (Yagi Outdoor Antenna, 3500 sq ft model) changed everything. I’m now holding steady at 4 bars of LTE, and calls, texts, and data all work so much better. Setup takes a little thought: you’ll need to look up your nearest cell tower direction for your carrier and make sure the indoor unit and outdoor antenna are 25–50 feet apart to avoid a feedback loop. Because I have a metal roof, I mounted the antenna on a pole away from the house using the provided brackets — that worked perfectly. The free app also helped verify signal strength and distance between components. I was surprised this worked so well with just a 1-bar starting signal, since many boosters say you need 2–3 bars minimum. It really delivered. Also worth noting: while this product page shows a 3.7-star average, there are several different SureCall models listed under the same page. I purchased the Flare 3.0 specifically (currently $379.99), and I’d give this model 5 stars all day and night. Maybe one of the other versions didn’t perform as well, but this one exceeded my expectations.

Update 17 Dec 2023: After using, or attempting to use this booster for several months, I am lowering the rating to 2 stars and putting this firmly in the not recommended column. And the only reason it gets the second star is that technically it does work if every star aligns in your favor and you are willing to sit next to the booster itself. As stated in my original review, the signal would not push its signal even into the next room. To combat this I moved the indoor booster itself into the next room where it would be more useful. Unfortunately, this did little to improve the usage of the device. While it still does connect if you manually go into airplane mode and out again while standing next to the booster, it completely drops its connection only stepping roughly 10 feet away within the same room and latches back onto the tower itself which in my case is a 25 db loss. As you can see in the most recent screenshots of signal strength, when it does connect it's a huge boost in signal, but to lose connectivity in the same room is a significant problem with the device as it stands and reduces its usefulness to all but the most limited applications. Original review: We live in an area where for whatever reason, we don't get a great cell signal at the house. AT&T signals hover at 2 and even 1 bar, and the T-Mobile signal might as well be coming from the moon. I finally decided to find a solution to get a better signal. Bottom line first, this product did raise my db gain when it was finally set up in a way that would work. But it took a lot of effort to get it there. And, the booster's range itself leaves a lot to be desired. I started with an out of the box installation. Mounted the included directional antenna and aimed for the tower, then ran cable from there down to the cable head I put in the garage to route it up to where the signal booster would need to sit. Plugged it in and got an immediate jump in signal. Then I made the mistake of walking into the next room, where I lost 3/4 of the boost gained and it never came back even in the room with the booster. Repositioning the booster then put it into the 'flashing yellow' warning loop where it drops power to avoid antenna inference, so at that point I stepped away and did further research into why. So why did this happen? Well it's a function of the design of how this type of device works. To do it properly you must have enough separation between the antenna and the booster device so that the antenna is not just looping the booster signal. To make this work, you need to dive into the the instructions that do not come in the box on antenna interference, and there you find that you need 25 feet of vertical separation or at least 50 feet of horizontal separation to work properly. Well, anyone with a single story home or a split level like ours with all the living areas upstairs will never get that 25' unless you put the booster in the basement. And since it struggles to reach the next room, that's not really a solution. So what you are left with is getting that 50' run somehow. Unfortunately, the company has chosen only to provide a 50' cable which by the time you actually route it to get it inside the house you will need more than that. They also do not include any adapter flat cable to route through a window if needed. They also flat out tell you that if you do need to go longer, you need RG-11 low loss coax and not the RG-6 they included so you don't get signal loss from the antenna in that long run. For a $300 kit to then make you go and have to buy a $50 cable on top of it when they know you will very likely need is pretty lousy. They don't even spring for the RG-11 for the 50' cable they give you which would at least be a step in the right direction. In the end, I had to relocate the antenna to the farthest corner of the house and ended up purchasing a 100' RG-11 cable from here on Amazon that I used to route it all the way back to the cable head point and connect from there. Once that was done, I did indeed get about a 20 db gain and a 2 bar jump on my AT&T signal. Unfortunately, I only get that jump when in the same room as the booster. As soon as we move to the next room we lose those bars and at least half of the gain which is frustratingly low power for the booster. So in the end, does it work? Yes, but you need to go in with the understanding that it's very likely you are going to need more than this kit to make it work correctly unless you have the right type of house and planned placement. And based on my own experience now with the added parts needed and the general weakness of the booster signal locally, I think the kit is significantly overpriced. At perhaps half the price as is or around the $200 range if they included the right type of cable needs would be a much more realistic price point. As is, it's a steep ask for a small antenna and booster to plug into it.

We got lucky and happened to already have a pole mounted in just the right spot on the roof. So we had only to attach the antenna and run the included 50 foot coax cable along the roof to the appropriate room, down the siding, and up through the floor. That's the hardest part, which my s/o said went much more smoothly than he expected. Once you get the coax cable inside, it really is just plug and play. It couldn't be simpler. We just assumed there was some sort of programming we needed to do and were surprised to learn that we were done. It was working! After installation, we were able to watch youtube videos in multiple rooms without issue. We made a phone call between the middle of the house (not far from the outdoor antenna), and the room at the opposite end of the house from the indoor piece, worked great. I ran a speed test in the room with the indoor piece, which previously got little to no signal (phone calls and texts were often not possible). I got 13 mbps down and 3 up, and the down speed was much more consistent than the speed test before install. I realize that objectively speaking, 13 mbps is appalling, but this is a place where 1 mbps passes for a reasonable internet speed, and that's on ethernet. I walked all around the outside of the house a couple of times with my Android in field test mode prior to installing. The numbers ranged from -120 to -101 (-101 being the spot underneath where we installed the antenna). Indoors, in the room that we put the inside piece, the field test number was -125 prior to installation. I can't remember what the number was after installation... I think it was -100. I'll have to test it again the next time I go there. Oh, the distance between the indoor piece and the outdoor antenna was roughly 45 feet horizontally. 25 is considered the minimum, I believe. We've had it installed less than a day, but we love it so far! If I remember, I'll come back and update after some time goes by.
