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.

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.

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!

Decent product. Easy installation. Range lower than expected. Its advertised for 2K sq ft. but signal outside a 800 sq ft room where the indoor antenna is installed is very weak. Works great inside the room. I went from having no reception to 5 bars. Awesome customer service. Liam contacted me after I received the product. I was short a bit of extra cable to get the antenna where I needed it. Liam sent it to me free of cost and took care of my need. Would give 5 stars if range was greater but still very happy with the purchase.
