My Wife is Happy
My wife has a café in the central part of the town, where the signal is bad. I bought her this device to amplify the reception and it really helped. The coverage has become much better, my wife liked it!
Dear Garry, thank you for the review. We are glad that your wife liked the device. Kindest regards, Support team.

Don’t let negative reviews fool you
Thanks to this booster we have full service to talk and text. We ran the cable into where the other cable goes into the house. The system allows us to use phones in the basement and the detached garage.
Dear Keone, Thank you for your feedback, it means a lot to us! Best regards, Support team.

Useful thing
In my town the cell signal is very weak. I got very low data speed using LTE. Usually I could get one bar. After installing I am getting 4 to 5 bars, good for calls, texting and surfing the Internet. The price is rather high.
Dear Stevie, we appreciate your review. Thanks and regards, Support team.

Worth a try
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.
· Martin Coval · Verified Buyer · 16-12-2024
Added 3 bars of service!
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.

It boosts your existing signal
I highly recommend this model for signal boosting in your home or office. I have O2 and Vodafone phones in my home. Both were getting one or no signal bars in the interiors of my place. Calls had to be made near a window for any sort of clarity. Dropped calls were the rule, not the exception. I received the booster in a timely manner and everything was as described. It took me about 40 minutes to install the antenna, including the mounting pole, run the cable, and mount the booster. Within 5 minutes of installation, all the phones now get 3-4 bars signal. I tried to point the antenna directly towards the cell tower in order to gain the greatest signal possible. I am absolutely satisfied with this booster and highly recommend it to anybody suffering from constant call drop.
Dear Alex, good to know that we could help you. Kindest regards, Support team.

Affordable & Effective
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.

· David G. · Verified Buyer · 04-12-2024
You Won’t Regret
The set up of the booster is very easy and fast. It took me about 30 minutes only. After the installation the mobile phone was able to catch 4 bars in the room where there used to be no signal at all.
Dear David, thank you for the feedback. We are glad that your problem has been solved. Kindest regards, Support team.

· Bob Carter (United Kingdom) · Verified Buyer · 11-11-2024
Good Model
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.

Mount it correctly and it works well
This is a good option for increasing signal in the house that is not able to receive well. Repeater functioned fine from the box. Installation was uneventful. But the outside cable could have been a little longer. The basic instructions were reasonably well written and clear. On the whole a good deal at great price.
Dear Doc, we appreciate your review. Thanks and regards, Support team.
· Lena P. (Poland) · Verified Buyer · 07-11-2024
Great result
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.

See No Drawbacks
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.
· Patricia H. · Verified Buyer · 16-10-2024
Improves Reception
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.

So many models
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.
· Adrienne Cavalluzzi · Verified Buyer · 23-08-2024
More signal bars for sure!
I bought this because I live right on the edge of a cell coverage area. Sometimes I had to go outside to make a call because the signal was too weak. The signal strength climbed to 4 bars.
Dear Adrienne, Good to know that we could help you. Best regards, Support team.

When me and my family, who were also very interested in solving our troubles, found out about Mobile-signal-boosters, we noticed their benefits over other companies. And, eventually, we chose them because we loved their true and detailed descriptions, their attractive prices and a wide range of products we could choose from. We needed a model with wide working range that wouldn’t cost us a fortune, and we found it.
Jeremy Herbert, MorecambeOne of the main advantages of Mobile-signal-boosters is that the company provides a user’s manual in the installation kit. Due to the instructions given we were able to set up the repeater on our own without any professional help. Everything is very simple and clear, moreover we didn’t have to purchase any extra details or mountings in order to install the device.
Jennifer Stanton, DarlingtonI purchased a mobile phone signal booster at Mobile-signal-boosters in order to improve a poor signal in my café which is located in the underground. Previously, my visitors used to complain about signal issues, but as soon as the device was installed and started to work all problems disappeared. The mobile connection in the café became strong enough, which was immediately noticed by my visitors.
