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

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.

Picked this up for my 5th wheel. In my current location/campground, I get about 1-2 bars 4G with Verizon. This does work, don't get me wrong, it just doesn't work as well as I hoped. The main issue seems to be distance between the two antennas. Apparently I can't get the exterior antenna far enough away from the interior antenna to remove interference. I am constantly unplugging the base unit to reset it and get at least 5 minutes where it doesn't think there is interference. Still increased my download speed by at least 2x though. Maybe I'll call tech support and ask someday. Not hard to set up, you just need to buy (or already have) a mount for the exterior antenna. I used a piece of 1" PVC, zip tied it to my AM/FM/HDTV antenna on the top of my 5th wheel and went from there. Not hard to do at all.

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

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 struggled for years with weak cell signal inside our house, dropped calls, slow internet and texts that wouldn’t send. After installing the Flare 3.0, the improvement was immediate. We went from pretty much no signal to reliable service throughout most of the house. We are now able to make and receive calls and the 5G internet is much faster and doesn’t buffer. Installation was straightforward once we positioned the outdoor antenna correctly with the help of the app, If you’re dealing with weak indoor cell reception, this cell phone signal booster is highly recommended. It’s made a noticeable difference for us. Wish we bought it years ago.
