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.

We had between 0 (the SOS icon on iPhone) and one bar at our small retirement home here in central Florida. To get decent signal, even for text messaging, we had to go to the middle of our street, where it would sometimes work. We had talked with neighbors and one of them had purchased something through AT&T but said they were very disappointed. After reading through several reviews we decided to purchase the Sidekick. This was our experience: 1. Everything was packed very professionally, all the components were described well in the instructions, and nothing was missing. 2. We followed step by step through the process of getting things installed correctly, the most important being the outside antenna and ensuring that we had things 'pointed' in the right direction. 3. The inside and outside cables were plenty long enough to effectively place the outside antenna in the best location and to install the booster in a central location in the house. 4. One thing we really liked was the separate 12" micro cable that allowed us to put cabling through the window and still be able to shut the window. Since this cable is designed for a closed window there isn't any kinking or other issues. Nice attention to detail by the manufacturer. 5. We followed all the instructions to optimize placement and less than 10 minutes after we started I was in my home office enjoying a full four bars. 6. That evening Liam, one of the technicians at HiBoost, reached out to me to make sure everything was working well. I relayed to him that we were very pleased and my wife and I were finally enjoying simultaneous video streaming with no interruptions. He asked for a few screenshots of the final numbers and agreed that we were set up very well. 7. What made this very timely for us was that our internet went out for the past 3 days, and my wife and I are both tethering to our phone hotspots from our computers and enjoying a fast 5Ge connection. 8. We're very pleased with our device, no more missed or dropped calls and a nice backup for us when our internet goes out here in our community. 9. For us the value is great, signal strength is always 3-4 bars, and no issue. Highly recommend this product and this company!

We live in a low area surrounded by trees with poor line of site to any tower. On a good day we could get a single bar, and have relied on wifi calling and texts have been hit and miss. We've had some success with cheaper cell boosters in the past and decided to try something a bit more robust so ordered this unit. Installation was simple, took about an hour. The Signal Supervisor app is easy to use, and cellmapper.net was very helpful locating a couple of towers. After adjusting the direction a bit, we are getting 3 to 4 bars in most areas of our ranch style home. The worst we get is 2 bars in some parts of the basement. No more dropped calls, texting works as it should. Overall we're thrilled with this booster. I noticed a negative review that called out poor customer service, so I want to give my own review of that. I barely had time to unbox the system before recieving a text message from tech support (Liam) asking if I had any questions or needed any help which honestly blew me away. I answered to say I didn't have time to work on it but would over the weekend. Fast forward several days and Liam checked in again to see how things went. I'd say this is above and beyond expectations. Even though I didnt have any problems with installation and setup, I felt confident that I had a support team ready to help if I needed it. Great product and great, attentive support. Well done!

I recently purchased the HiBoost Cellphone Booster, and I couldn’t be happier with the results. I used to struggle with weak signals, especially in certain areas of my home and while camping, but this booster made a huge difference. The setup was straightforward, and the performance has been consistently strong—now I get clear calls and fast data in places that used to be dead zones. What really stood out, though, was the incredible customer support I received from Liam. He was knowledgeable, patient, and went above and beyond to help me get everything working perfectly. He guided me through the installation and even gave me some great tips to optimize the signal. It’s rare to find someone so genuinely helpful. Overall, I highly recommend the HiBoost booster to anyone struggling with poor signal, and if you get the chance to work with Liam, you’re in great hands!

This system works great in our remote cabin. It was straightforward to set up and dial in with clear instructions for locating the strongest signal. We went from 0-1 bar inside the house to 3-4 which has been very helpful when the wifi goes down. We could not send/receive anything besides plain texts before and now we have no problem sending pics or videos.

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.

Easy setup with the app.Read the instructions first!! Be safe mounting the outdoor antenna!! Great value for a good quality product.I live in a bad cell area so this product is exactly what I needed. Went from 1 bar to full bars!! No more dropped calls.

Living in a rural area, I have access to a single cell tower, and when I put a metal roof on my house, my signal inside the home was degraded significantly. After comparing brands and prices for many hours, I picked the HiBoost Sidekick and I'm glad I did. I received the booster and did a temporary mount on a pole. I was unable to get any change in signal quality, though I found my tower ok and adjusted the antenna direction and height multiple times. I reviewed the documentation and put in a support request via the websites chat feature, which was convenient and was answered very quickly by Yoselin. I had already determined the issue was my towers stronget signal was on coming in channel 66, which after reading the specs more closely, I found was not supported by my Sidekick device. After speaking with the tech, Yoselin, I was told to how to turn off channel 66 in the supplied App, and was able to force the booster to use a different channel. After this I was able I was able to get a small signal boost, but it was intermittent. After monitoring both my phone and my room mates for a few days, and speaking with Yoseline we found both were still connecting on channel 66 from time to time, instead of the booster, as the other channels were much weaker, even with the booster detecting and improving the signal. Yoselin asked if I would exchange the device for one that supported channel 66, and within a few days, I had received the new booster and swapped it out for the one mounted on the pole. I noticed an immediate improvement in signal and voice call quality and so I then made the effort to do a roof top mount, which improved my reception even more. None of this would have been possible without the assistance of Yoselin from tech support. She made multiple contacts with me over a period of three weeks, as I was unable to work on this install consistently during the week due to other commitments. I am very impressed with the quality of the both the device and the support. As for the device, it did take some time and effort to find my tower, mount the antenna and run all the cabling internally, but that is to be expected, and the device works so well and has improved signal at my house so much that we no longer t have to go outside to keep calls from dropping or to make a call. Very happy with this purchase and the support I received from Yoselin.
