Definitely meets my expectations and I was able to maximize the cell signal gain so I now have a usable data Hotspot if my Starlink fails. I live in a rural area of upper Wisconsin with only a single cell tower (Verizon) in proximity. I had been a Frontier Communications customer with old copper DSL which was the only option other than satellite but Frontier is in the process of abandoning the copper lines and, unfortunately, they are not running fiber to my location. So I installed Starlink for internet, which so far has been excellent, but wanted a backup option in case of failure/outage but my cell signal was not good (1 bar, sometimes 2 with DL speeds around 2-4 Mbps) so I purchased the HiBoost Sidekick. FYI, prior to purchase I downloaded and read their installation instructions and ended up emailing their support multiple times as I worked through my install plan - including installation of a grounded lightning arrester because we get a lot of thunderstorms up here. They responded to all my questions promptly. Using online sites and android apps I was able to determine the tower location (& bearing) and elevation difference from my home. I then installed the antenna using a compass app to set the degree angle to the tower bearing and also slightly angled up to account for the elevation difference then temporarily ran the cables through a window and to the location where I planned to place the booster. SUCCESS. I actually achieved maximum dB gain and was getting 14-20 Mbps DL & 1.5 Mbps UL so was extremely happy to finish the cabling and grounding. I then downloaded the app and used it to register the product as well as using it to disable 2 of the 4 bands I was switching between, including the "5G" band, because they were slowing things down. For reference, my disconnected Frontier copper DSL was 2.5 Mbps DL/ .5 Mbps UL so, as they say, everything is relative - so my new booster signal is fast. Oh, the day after I registered I received a text from HiBoost support asking how things were going and if I had any questions. So I have to say that my experience with HiBoost support both pre and post purchase has been positive. Now I hope this antenna lasts, especially through our snowy, cold winters...but only time will tell. Definitely recommend based upon my needs.

I recently moved and had no problems with cellular calls till the cold weather hit and the windows were closed. All of a sudden — and mysteriously to me — people started complaining that they couldn’t call. There was silence on the line and calls went directly to voicemail. And then I found that I even had trouble calling out — no signal. Well, one bar but not enough to carry a call. So, I tried WiFi calling but there’s no caller ID, just a generic “Wireless Caller” message on the other end and no one would answer. Not good enough. I investigated signal boosters and settled on the HiBoost mostly for the good customer reviews and the price. I installed it yesterday. Mounted the antenna just under the overhang of my garage roof (would have been even better up on the roof but I’m klutzy). Aimed the antenna approximately in the direction of a tower in the next town (There’s a much closer tower but I live in the shadow of a steep hill; thus my problem), strung the 30’ cable across the front of the house and was able to bring it in alongside the TV cable. A ribbon cable is provided for just such a situation or for coming in through a window. Hooked it up and without needing to call support, my phone jumped to 4 bars within seconds. The signal does drop as you move from the base station. 3 bars about 20’ away then 2 bars in the back of the house with walls intervening. But even at 2 bars (or even 1 — it can fluctuate), Call performance is still good. I’m actually astounded. The thing works.

This product was a total lifesaver. I moved into my new place and immediately realized I got no cell signal inside. I work out of the house so that was going to hw a disaster. Bought the Hi-Boost and couldn't be happier. It is like having a miniature cell tower inside your home. The cell signal is excellent throughout the house. It was really easy to install and they have amazing customer support. They periodically check in with you to see how the product is performing. That is really unique. I would HIGHLY recommend this product to anyone who is struggling getting a cell signal in their home.

First sidekick I ordered got stranded somewhere in Amazon's delivery network less than 15 miles from my home. Second sidekick arrived before the first one and I canceled the first one. Guess that $10 difference in sale price matters on the prime shipping behavior. Shipping box was fine but retail box inside was damaged - seam was ripped along one edge and it looks like it was dropped with the dent in the retail box. Clear-coat sticker on the display looked nasty and could not clean it. until I got my fingernail under the edge to remove it for a nice shiny display surface. See photos of those things. Bought the booster for using with my camper, tested it at home with the antenna upstairs and the booster downstairs with the coax running down the stairs. Yay - it works, no smoke came out of it and the LCD display was intact despite the box being damaged. My cell phone had two bar of service that went up on the band in use for T-mobile 5g to five bars of 5g once powered on. Speed test before and after went from ~70mbps download to ~130mbps download, I forget the upload speeds but they also improved in a residential suburb. Trying with my AT&T 4g LTE hotspot, no real difference in speeds even with moving the antenna to point at an AT&T tower. I was getting ~20mbps down and close to 5mbps up on AT&T. Other locations with the camper/hotspot I have seen 75mbps down and 25mpbs up on AT&T with the CAT4 modem. For reference I get 550mbps down over wifi on the testing devices and on Ethernet devices on my home internet service, so the various device 5ghz wifi speeds are not the bottleneck. The power supply is 12v 3.0 amp so it should be able to have a direct tap into the camper 12v system with a fuse, maybe one of these power converters (https://www.amazon.com/dp/B07YZBLCY5/) with the correct socket adapter and a power switch will work when boon-docking verses using an inverter. That is how my hotspot is wired in the camper already. One gripe - the app - it has 2.5 stars out of five in google play store for a few reasons. It works. I do not feel it is needed though, but does offer some remote metrics when aiming the directional antenna. My complaints about the app are: 1 - you need to create an account on their portal/website using both your email and your cell number. 2 - Signing up/using the app you are registering your product with your amazon order number for tracking and activation date for the 3 year warranty, so have that info on hand. 3 - while all cell boosters need to be registered with the carrier with your address so they can knock on your door when interference is detected, I am planning to use it while camping when needed at the site I am at that day, with the two different carriers. The app took my gps location from my phone to tag home as where the booster will forever be. 4 - trying to connect to the booster over bluetooth (me choosing to not use wifi despite the app's persistence to allow it to radio home over wifi for push notifications) worked for registering the device, but then I could not access the device and got an error telling me to say within 20-30 feet for bluetooth. I was 2 feet away. Eventually after another 2-3 minutes of trying to figure out how to refresh info in the app (I never found a way), the bluetooth link reconnected and I was able to see the signal meters for all for frequency ranges. Association/pairing of bluetooth is done via the hiboost app not the phone's bluetooth interface such as for your car/speaker/headphones. 5 - The majority of the app (75%) seems to be a social app with "share your experience/rating/photos" and "here is our entire product line with marketing info for you to buy another or share with people". I wanted the app for the remote signal meter viewing and nothing more. Tech support is embedded in the app too. I believe the sidekick has an EPS32 in it by the name on the sticker of "what's inside" which, that family of products, can do web servers, wifi, bluetooth and more and are heavily used in IoT devices. Knowing the history of ESP32 performance/design explains a few things in my experience so far, such as the bluetooth connectivity and recovery time needed. The FCC ID on my sidekick is OWWF115705S and contains FCC ID 2AC7Z-ESP32WROVERB and contains IC 21098-ESPWROVERB as part of the model no F08G-5S-IOT. These are things I wish I knew before I bought it. A search for that FCC ID returns a different HiBoost product when you see the external photos the FCC have on file. I will keep it as it seems to work despite being in a decent cell service area where I would not use it normally. Just wish the box was not damaged for transport and storage when not using it and the red word "alarm" was not lit up on the LCD screen for two of the four bands, but that could be due to using in the suburbs.

So I bought this product because I wanted to increase my 1 bar cellular service signal in my house. And after some research, I just realized they had these nice little cellular booster devices that have been out for the last few years. There's a lot of choices out there with a large range of prices too. Which makes it hard to make a decision. With luck, I tried this Hiboost and a cheaper brand. After some comparison, Hiboost clearly put out a better signal than the other cheaper brand. So don't be scared to spend a little on this purchase, quality makes a difference. This particular package had nice connections and the parts you need to get it up and going quickly. The best part to me was this model gave you a display not just some silly LED lights so that you could actually see what bands are coming in and at what strength. It helps you evaluate your input signals too. This also has an app that you can get that coordinates with the unit to give you input/output values for adjustments. But I never made it that far yet. Nice to know that it was there though. My one caveat here is don't expect a huge boost to you signal in your whole house. It's just not going to happen. So all these devices claim to give you like 2000-4000 sqft of boosting but I think it is a load of c###. Yes I got like 4 bars within about 3', 3 bars out to about 8', ad 2 bars out to about 10-15', and after that I don't think I'm getting any additional help. So to me plan on only boosting the room the device is in unless you buy output antennas for other areas. Fortunately I only needed this for items in the 3' range so it worked well. And the big factor was with the increased signal you get a bump on your speeds. That was big.................The bonus here was the customer service. They reached out to me right after purchase for any technical help I needed and then even sent me a directional extended output antenna to help me with my issues. That was a pleasant surprise and generally unheard of. The new antenna helped some but not like I feel it should have. But of course I'm not an expert. Anyway I totally recommend this unit and this vendor if not for the device but especially for their support of their product. They genuinely seem like they want to get it to work for so just don't have large expections on this actually boosting more than the room it's in and you'll probably very happy, especially with HiBoost's customer service.

HiBoost Sidekick Cell Booster – November 17, 2025. Cell providers in our neighborhood have no nearby towers—the closest one is about 4 miles away—so our signal strength has always been extremely poor. Our RSRP (Reference Signal Received Power, measured in dBm) consistently hovered between –110 and –118, far below the acceptable –90 range, and we frequently dropped calls. It was incredibly frustrating, and our provider had no solutions. Out of desperation, we researched boosters and chose the HiBoost Sidekick, which works with both Apple and Android phones. We use Apple. The installation kit includes an outdoor antenna, two NM-SMAM transmission cables (32 ft and 16 ft), the indoor signal booster with 120-volt power supply, an indoor whip antenna, mounting hardware, and a manual. Everything arrived well packaged and in excellent condition. After confirming all the parts, we read through the setup instructions. The manual includes a helpful diagram showing where each component goes—the outdoor antenna, the transmission cables, the indoor booster, and the power supply. That part was straightforward, but some of the actual setup steps were less clear. Depending on whether you use Apple or Android, there are different methods for checking signal strength. For Apple, you dial *3001#12345#* to access the field test mode. We verified we had a weak signal, but at least some signal. The next step was to download an app called CellMapper. That’s where things went sideways—the app couldn’t determine my location and showed no nearby towers. So I downloaded another app from the App Store called Cell Towers, and that one worked perfectly. It zoomed into my location and let me scale the map to see exactly where the towers were. Once I had that information, I knew which direction to point the unidirectional antenna. I did a temporary test setup and immediately saw an improvement, which convinced me it was worth doing the full installation. The outdoor antenna comes with U-bolt mounting hardware for a pole up to about 2.25 inches in diameter. Fortunately, I had a roof vent pipe in the perfect spot. (If you don’t have a pole already, Amazon sells mounting poles compatible with this booster.) I used the 32-foot cable, ran it underneath the eave, drilled a hole through an exterior wall, and routed it into the house to the booster unit. Once everything was connected and powered, my RSRP improved from an average of –113 to –90, giving me four full bars. I’ve only had it installed for a day, but so far I’m extremely pleased with the results. One more note: my installation location is on an outer wall, not far from the center of the house. If I’m more than about 40 feet away from the booster in another room, my coverage drops back to almost nothing. If I had mounted it in a more central location, I’d probably get better whole-house coverage. In the end, it was an aesthetics-versus-functionality trade-off. Still, when I take calls in our centrally located living room, I have no issues at all. Bottom line: So far, the HiBoost Sidekick has dramatically improved our signal and eliminated dropped calls. I’m very happy with the performance.

This was bought for my vacation home that had poor reception from Verizon. The local cable company wanted a extremely high labor charge to direct bury cable from the pole to the house so we added a hotspot and limited data instead, that part has worked out great. We limit the hotspot for the TV only and force the family to use their unlimited data on their phones. A cell booster is exactly what we needed for the smart TV. I landed on the sidekick from HiBoost. Original install was fairly straight forward, I knew exactly where the cell tower was and the outdoor antenna was mounted on the VHF/UHF antenna on the roof. Last year it worked great, boosted the signal just enough to give everyone's phone four bars and trouble free phone use. The smart tv hooked right up to the internet for LTE. Year one, everyone happy. Opened the place up this year and noticed the booster was dangerously hot. Could barely hold onto for more than a few seconds. The second thing we noticed that the cell service was back to "poor at best" so the booster was powered down and brought home. Now, I called customer service and left them all my personal information and what the symptoms of the booster was on a voice mail. The next day I received a text from a technician about how he could help. I told him the situation and he asked if I could send him a picture. I informed him that I could but this was not complete because the antenna was still mounted at the cabin. Over the next couple days we went back and forth about the unit and he kept telling me that it couldn't work with out the outdoor antenna. All I wanted was to send this unit out to Hiboost and have them send me a replacement because this is advertised as "Trouble Free Warranty" and this is obviously not trouble free. As I write this I am going on week two of the phase where I get Hiboost to warranty their defective product and hopes are getting slim. I now wish I would have went with the WeBoost product as all the reviews I am reading they are the superior product. This unit isn't bad but their customer service is "poor at best"

Impressive! Exceeded expectations. Like most people, I researched different ones and looked at reviews, with many people saying these things don't work at all. Well, I can say that this one works. As soon as I plugged it in, my phone went from 0 to 1 bars to four to five bars, from no phone service to high-speed streaming. I am in and off grid Cabin in the Woods and this is my only source of connectivity or Internet, and it is all I need. Good value, easy setup, greatly improved connectivity.
