"This cellphone booster completely transformed my signal strength and coverage at home and in my office. Fewer dropped calls and faster data speeds are now the norm. I found installation very straightforward, especially with the helpful app. The FCC approval also gives me peace of mind. While finding the right spot for the antennas took a bit of trial and error, the result was well worth it. Overall, the performance and reliability are top-notch."

"I use this device for mobile setups in remote areas, like camping trips, and it delivers a strong signal where there was none before—even outperforming my friend's car-mounted booster! I had some issues with the app and hardware revisions, but the customer service I received was truly exceptional. Noah went above and beyond to resolve my concerns, making me a loyal customer. I’m grateful for the extra effort and fast responses."

"Before getting this HiBoost booster, my phone barely had any signal and dropped calls constantly. After setup—which was much easier than I expected—I instantly had full signal strength and crystal-clear calls. Their customer support walked me through my questions with patience and expertise. My data speeds have improved dramatically, and working from home is now frustration-free. Absolutely worth the purchase!"

"I put this booster through its paces at three different spots with notoriously bad signal, and the results were impressive. Speeds, latency, and packet loss all improved dramatically with the device on, especially the upload speeds and reliability. I’m honestly amazed it lives up to its claims. Highly recommend if you need dependable internet for streaming or working while camping or traveling."

"As someone who travels coast to coast with AT&T, I was frustrated by poor signal and constant service drops. After installing this booster, I barely ever lose connection—even streaming Netflix and making calls on the road. It’s a game changer for frequent travelers. While it costs a bit, I’m glad I tried it instead of buying a new phone."

"We have some valleys nearby where our phones always lose signal. With the Overland booster, we consistently maintained at least a usable 4G bar, could make calls, and receive texts. We ran several tests and it worked every time. Great product that delivers real-world results."

"After thoroughly researching my options, I settled on the HiBoost unit, and I'm genuinely impressed! Our signal jumped from a single bar of 4G to five bars of 5G throughout my 4000 sq ft house. Calls and data are now seamless, and I can finally offload some traffic from the WiFi. The installation was straightforward with everything included, though the user guide could be clearer. What truly stood out was HiBoost's proactive tech support—Noah reached out shortly after my purchase and responded instantly to my questions, which is rare in tech support. The two recommended apps made optimizing the system much smoother. Overall, I love this product and the customer experience!"

"I bought HiBoost for my elderly mom's home, where cell signals were nearly non-existent—making her Medical Guardian device unreliable. To my relief, the signal improvement was phenomenal after installation, and now the MG service works from anywhere in her 2,400 sq ft house. The unit came with high quality hardware and a handy cable for routing through windows or doors, which saved me from drilling holes. While the SignalSupervisor app was a bit frustrating to use, I found it easier to watch the booster panel directly during setup. Overall, this is a good unit that delivers great value, and I'd definitely consider HiBoost for future needs."

"Living in a low-lying area with poor cell reception, I was amazed by how much the HiBoost Sidekick improved our connectivity. Installation was straightforward, and the Signal Supervisor app made pinpointing the right tower direction easy. Now, we consistently get 3 to 4 bars throughout our ranch-style home, including the basement. What truly impressed me was the proactive customer support—I received a helpful text from tech support before I even started setup! This level of attention made me confident in my purchase. No more dropped calls, and texting works perfectly. Highly recommended!"

"Our neighborhood is notorious for weak cell signals, with the nearest tower miles away. After trying the HiBoost Sidekick, I saw my signal strength jump from an average of –113 to –90 dBm, giving me four bars. The kit was packaged well, and setup diagrams were helpful, though some steps could be clearer. Once I figured out the best antenna direction using a mapping app, the results were immediate. While coverage fades in distant rooms, the performance in main living areas is excellent. Overall, this booster has eliminated dropped calls and made my experience stress-free."

"At our retirement home in Florida, we struggled with unreliable service—sometimes only the SOS icon appeared. After installing the Sidekick, we now enjoy 3–4 bars of signal throughout the house, and both calls and video streaming are smooth. The cables were long enough for optimal placement, and I appreciated the thoughtful window cable design. When our internet went out for several days, we easily tethered our computers to our phones with strong 5Ge speeds. On top of that, customer support checked in to ensure everything was working. This booster has truly been a game changer for us!"

"After installing this booster, I noticed a huge improvement in my cell signal throughout my home. Dropped calls are now rare, data is faster, and coverage is much more reliable. The setup was straightforward, and the app made it easy to follow the steps. I like that it works with all the big carriers and covers a large area. Even though I had to spend some time figuring out the best antenna placement, the results have been worth it."

"I use this booster for camping and remote trips, and it has been a game changer. My friends were amazed we could stream video in places where we usually had no signal at all. Customer support went above and beyond when I had a hardware issue, sending multiple replacements until I was satisfied. The service was honestly the best I’ve experienced—super responsive and dedicated."

"I was skeptical at first, but after setting up this HiBoost booster, my phone now shows full bars and calls are crystal clear. The instructions were simple to follow, and when I had a question, customer service quickly helped me out. Data speeds are much faster now, which makes working from home or streaming so much easier. I highly recommend it if you struggle with weak reception."

"After struggling with poor cell service in our tree-surrounded area, I found the installation of this booster to be a breeze—it took just an hour and the Signal Supervisor app made setup straightforward. Now, we’re enjoying 3 to 4 bars throughout our ranch-style home and have no more dropped calls or missed texts. What really impressed me was the proactive customer support; Liam from tech support reached out multiple times to check in, which gave me confidence in the company. This product exceeded my expectations both in performance and in service."

"Living in a neighborhood with no nearby towers and terrible RSRP values, I decided to try the HiBoost Sidekick. The installation kit was complete and well-organized, and after some trial and error with tower-locating apps, I got the antenna pointed in the right direction. My signal strength jumped from -113 dBm to -90 dBm—now I have four full bars near the booster and no more dropped calls. The only minor issue is that coverage fades in rooms farther from the booster, but placing it centrally would likely help. Overall, I’m very happy with the dramatic improvement."

"At our retirement home in central Florida, we used to get zero to one bar and had to step outside just to send a text. The Sidekick arrived well-packaged with thorough instructions, and installation took less than ten minutes. We especially liked the window micro cable for easy setup without cable damage. Now, both my wife and I can enjoy full bars and seamless streaming—even using our phones as hotspots when the internet is down. Liam from HiBoost checked in to ensure everything was optimal. No more missed calls or connectivity issues—the value is fantastic, and I’d highly recommend this device."

"Living in a cell signal dead zone, I was desperate for a fix. After installing this booster and properly positioning the antennas, I saw a jump from 2 bars to 5 bars throughout my house—even in the basement. The improvement was incredible, and the feedback problems disappeared once I followed the instructions about antenna separation. We’re finally able to make calls and use data anywhere indoors."

"I live in a ravine where cell service is non-existent. With this booster, I went from zero to four or five bars near the antenna, which is a huge win. The setup was easy and I managed to create a functional WiFi and phone solution for my whole house using a hotspot and an outdoor access point. The only downside is that the strong signal is really just in one room, but for my situation, it worked out."

"Inside my mobile home, T-Mobile signal was barely usable at –120 dBm. After setting up this booster, my signal shot up to –80 dBm instantly. Calls are clear and data is fast now. The installation was straightforward, and I didn’t even need to adjust the gain. For anyone with weak indoor reception, this is a reliable and affordable solution."

"Living in a rural area, I've constantly battled weak cell reception, but this booster made a huge difference. My house is over 7,000 sq ft and now has full 5G coverage everywhere. Everyone in my family, regardless of their carrier, enjoys clear calls and fast data speeds. Installation was a breeze, taking about an hour, and all the cables and hardware were included. The FCC approval also gives me peace of mind that it's safe and reliable. If you have a big house or live somewhere with spotty signal, this device is a real game changer."

"Before purchasing this, my suburban home and basement had almost no Verizon signal. After setting up the booster, I now get consistent 5G throughout my 2,800 sq ft house and barn. My work video calls never drop, HD streaming is smooth, and my phone battery even lasts longer since it's not searching for a signal. The instructions were clear, especially about antenna spacing, and setup took only an hour. It's well worth the investment for reliable, fast connectivity."

"We always struggled with signal dropouts in our semi-rural home, but after installing this booster, those problems disappeared. Setup was quick and effortless, and now both calls and data are far more reliable. With several devices in our household, this has become essential for us and a great value overall."

"After installing this booster, I've said goodbye to the constant stress of searching for a signal. My 5G and 4G reception is consistent throughout my 2,000-square-foot home, and I’ve noticed a significant drop in gaming lag. The device feels sturdy and well-made, and I’d recommend it for any household."

"I put this in my camper, and I was shocked at how well it worked—went from no bars or just one to four bars! Signal quality is so much better now, making a real difference when I’m on the road."

"I bought this so I could actually get calls inside my metal building where I run my business. Other boosters let me down, but this one finally solved my dropped call issue. No more missed calls—absolutely worth it!"
