Cell Phone Range Extender Nikrans NS550-GSM+4G

I was really astonished when I came to Mobile signal boosters. They have such a wide range of models that it was impossible for me to choose the one I needed. Fortunately, the manager helped me and I bought NS550-GSM+4G. This is a very good booster for improving calls and mobile internet. It isn’t large and the installation is simple. I like it!

Hello Sarah, we are grateful for your review. Looking forward to your next visit. Best wishes, the team of Mobile signal boosters.

Our cell phone service was absolutely miserable. Having no service wasn’t unusual. Now cell phones show 3-4 bars of service and calls go through much faster. Installation process can take a couple hours depending on your obstacles. You should follow the instructions. You will likely do a little drilling to run the cables. Everything I needed was included. This device was exactly what we needed.

Dear Martin, Thank you for the review, we greatly appreciate it. Best regards, Support team.

Because of the massive concrete walls of my countryside villa I practically had no mobile signal inside the building. But with this device everything is all right. Its installation is relatively simple, the working process is understandable. It serves me for receiving calls and using Internet. I see no drawbacks!

Dear Richard, thank you for the review. We are happy to have solved your problem. Best regards, Support team.

Recently we bought a cabin by the lake. It has a metal roof and is located in country far from a cell tower. In good weather, we might get 1 to 2 bar signal and frequently lost the signal. Since we installed the device, we keep a 3 to 4 signal, no dropped calls and our internet speed has improved. It’s easy to install. It took us under an hour. Wish we had installed it while we were living in the RV.

Dear Dragomir, thank you for contacting us, we greatly appreciate it. Best regards, Support team.

I like the booster, its quality and the result of its operation. It provided stable access to the Internet and perfect calls. Thank you for supplying such a wonderful product.

Dear Stuart, we are glad to receive your feedback. Thanks for choosing our product. Regards, support team.

We work in a small metal building and our cell phones would get no signal. Our manager purchased this booster. After the installation it doesn’t get 5 bars. We have 3-4 bars and that is plenty for the smartphones to work. The device has been working great for a few weeks now. We couldn't be more pleased.

Dear Joel, thank you for your feedback, it means a lot to us! Kind regards, Support team.

We have been using the booster for a month. The result is great! We have five bars, and the signal level has been increased twice. And the speed of mobile internet is excellent, we can watch live streams, there are no more interruptions. I recommend this device!

Hello Lena, we are glad to receive your review. Keep on enjoying your purchase. Regards, sales department.

I installed it in my guest house. There were only 3-4 bars in the hall, and hardly any in the rooms. When I plugged the booster in, it immediately started to amplify the signal and the phone showed 4 bars everywhere.

Dear Patricia, thank you for the review. We are glad that you are satisfied with the result. Best regards, Support team.

It seems to me that this device is a great example of an optimal price-quality ratio. It’s effective and not expensive at the same time.

Dear George, we are glad to receive your feedback. Your opinion is very important for us. Kindest regards, sales department.

I live in an area where Vodafone service is spotty. Making calls require additional effort. Well, I chose this booster and spent the money. I had to go up and down the ladder more than 100 times for installation. The result? It works. I went from zero to a bar of 4G to a consistent 3 bar signal. It is a full improvement over what I had but, for the money, I was expecting more. And another thing to keep in mind, the open signal app is useful in finding the direction of the tower you are receiving. In my case, the tower I thought was mine was another provider’s one.

Dear Cliff, we appreciate your review. Thanks and regards, Support team.

Outside our house we can make a call, but it may drop if it lasts long. Mostly data is either too slow to use or nonexistent. Indoors we might be able to initiate a call sometimes near the large windows. Indoors was actually a no call zone. No data are possible either. With the booster we can finally make calls and get data. You do need to follow the instructions on setting this unit up. It can be tricky. There should be a distance between outdoor antenna and indoor antenna. The antennas also should not point at each other. The power cord to the booster box is too short for us. I wish it was at least twice as long. This short cord on the booster unit hampers placing the booster in a good enough place. The instructions could be better.

Dear Kade, thank you for a detailed review. Kind regards, Support team.

I was hesitating what model to choose - this one or NS200-GSM+4G. So I called the manager, and she explained that for my cafe, which is a bit more than 450 m2, this model would suit better, as it has larger coverage capacity. I am pleased with the quality of mobile signal with the booster. The connection is stable, the visitors can make and receive calls without interruption and the Internet is steady and speedy.

Hi Bob, we are glad to know that now your visitors can enjoy a stable mobile signal. Kindest regards, sales team.
