How it works

While the outdoor antenna should be mounted on the roof of the building where you need to improve the signal, the indoor antenna as well as the phone signal booster box itself should be mounted inside the building.

The main rule is to fix your indoor antenna not closer than at a distance of 5 m from the external antenna, otherwise, they will interfere each other. Moreover, to achieve the best performance of this indoor antenna (it is responsible for spreading the amplified signal), you need to find a place in the middle of the area that you wish to cover with the improved signal. To place it at least at a 2-meter height over the ground is a must.

Amplifies the existing signal really well

Even though my phone has always had one bar of signal inside the house and probably two when I climbed up on the roof, this signal booster amplified it immediately to minimum three bars anywhere in the house. My house has a lot of metal in its structure, so it was quite hard for the signal to get through. After the booster installation, everything works brilliantly! However, I don’t think you will be able to get a better signal if you have zero bars in general, because to amplify signal it actually has to catch something, and it can’t emit the signal out of thin air. I actually didn’t have to place the antenna up on the roof, it was enough for me to mount it on the outside wall of the second floor (to the wooden part, for the better effect), and it worked out for me. So, no inconveniences.

Hello Tori! Good to know that our repeater solved your issues in the metal house. It requires some signal to work, you are right about that, but the weakest signal is enough. Best regards, Support team.

Worth buying

Living in rural area has its perks, but it also has its obvious troubles, and the most common one is poor signal. I’m really glad that my wife once stumbled upon the information about signal boosters online and we decided to buy one. It was easy to order, easy to put together, no need to buy extra parts, and it does what an amplifier should do: amplifies the signal at our house. It’s much better than it used to be, and the repeater is worth it.

Hi Adam, and thank you for your review! We’re always happy to help. Contact us if you need any more information. Best regards, Support team.

Super speed

This device helped me a lot. I’ve had terrible internet speed at my house before, and after I purchased and installed the booster, the quality of the signal and the internet speed grew really significantly. I installed the antenna on top of the roof, and, I think, it catches the signal pretty well there. Everything works perfectly, and my internet speed allows me to do everything I couldn’t do before.

Hello Calvin! We’re glad to hear that our booster worked out so well for you. Don’t hesitate to contact us if you have any questions. Best regards, Support team.

I regret not buying this earlier

To be completely honest, I regret that I didn’t buy something like this earlier, because I didn’t really trust online stores and didn’t think a repeater will work. My neighbor with the same signal issues recommended it to me, and she was absolutely right. It’s a very mighty device that looks compact and good in my living room, it’s easy to install, and the tech support team is amazing. My signal is really good now!

Hello Jesse! We’re glad that we could help you with purchasing your booster. Please enjoy the stable connection at your place! Best regards, Support team.

Great price and stable quality

My husband found this booster store online, and we were surprised with how quick the tech support was to help us. The delivery of the repeater was really quick too, it arrived within three days. The communication with the seller was very transparent and clear. The booster works well, no complaints overall. We don’t have any kind of signal troubles anymore. Have to say that our booster doesn't support 4G, though we didn't particularly want it.

Hi, Glyn! Good to know that you were satisfied with our service and the product quality. Contact us if you need anything else! Best regards, Support team.

Well worth the money

I’m an architect and interior designer, and I also recommended this booster to some of my clients who were having issues with the signal at their house. I bought one for my own apartment first, and it worked very well. The building is surrounded by other concrete and metal buildings, which caused severe disruption, as it happens to lots of apartments in big cities. I loved this repeater because it’s easy to put together and it requires no programming. It just quietly works out there on its own, doing its job really well. It’s absolutely worth the money I spent, because now I can use the internet smoothly, and never miss my phone calls.

Hello Katelin! Thank you for your review. We’re glad that you don’t have to suffer from poor reception at your apartment anymore. Best regards, Support team.

Helped us after installing a metal roof

After a few years of living in the same house, me and my wife decided to do some renovations, and we had our roof changed as well. The new roof is a metal one, and it obviously affected both phone and internet signals in a bad way, so we had to go outside to make calls and organize the rest of the renovations. We haven’t thought about it before, and now had to something about the consequences. We decided on getting a cell phone signal amplifier, like NS-300GD, and we weren’t wrong. It came in just two days, really quickly. I mounted the antenna on the peak of the roof, just to be sure that we’ll get a maximum effect possible out of it, and the inner antenna is located in the middle room of the house. Works very well, and our new metal roof is not an issue for our internet and mobile signals anymore.

Hi Mateo! It’s great that you and your wife are so happy with this booster model. We hope you’ll be just as happy with your renovations! Best regards, Support team.

Satisfied with the purchase

I bought it to use it at work, in a coffee shop. Our visitors had poor wifi signal before, which wasn’t the fault of the operator, and our router wasn’t to blame as well. Now poor interrupting signal isn’t a problem at our coffee shop anymore, and we all can have stable internet and clear phone calls. The signal got much better for both the staff and the clients, and everybody’s really happy about it.

Hi, Taslima! Good to know that your clients, as well as the staff, can have great signal now. We’re always happy to help! Best wishes, Support team.

Makes my grandparents happy

My grandparents had really poor signal at their summer cottage, and they always thought it was normal to have that kind of reception while being out of town, so they didn’t try to do anything about it. When I came to visit them, I had to walk around the house and stand near windows to get adequate reception on my cell phone, and I didn’t even mention the internet quality! That was horrible, and I decided to order them a signal repeater as a gift. They absolutely loved it! It works very well, amplifies the signal in their house, and even though they don’t use the internet too much, their guests appreciate it a lot.

Hi, Akash! It’s good to know that your grandparents and their guests, including you, are so happy with the signal now! Best regards, Support team.

Makes a major difference in reception

I tried a different brand from a different store once, and it didn’t work as well as I expected (and as promised), so I had to return it and look for other options. Then I bought this repeater after reading a lot of forums and reviews, and everything works smoothly now, even though I was already pretty skeptical about it all. I’ve got a decent signal outside the house, but it kept struggling inside, lowering my data speeds, and I got really tired of it. When I installed this repeater, I was very surprised with how noticeable the difference in reception turned out to be. It’s now a really rare occasion to not have all of the reception bars on my phone, and the internet speed is outstanding. It literally took me half an hour to install everything and to make it work. This repeater really rocks!

Hello, Timothy! Our team is happy to know that everything worked out for you. Thank you for your review! Best regards, Support team.

Case Studies

Phil Broad, Manchester

Very helpful service in choosing a booster.

One day I typed in “signal boosters” quite hopelessly, and Mobile-signal-boosters.co.uk website caught my attention because of the detailed, but still very understandable information they had. Out of curiosity, I asked their customer support, what model could they recommend to me, and was very pleasantly surprised to find out that the model they offered to me was really affordable even in my case, without any fine prints.

Norman Wheely, Aylesbury

My struggle with poor mobile signal.

I’m a musician who needs a good stable 3G internet in the studio all the time. The building where I rent it is located in the suburbs, but my The People’s Operator reception, despite my expectations, was extremely poor inside the building, which was an old factory rebuilt for rental spaces. The reason behind it were the thick walls of the building. I came to a conclusion that I need some device to help me solve that.

Edison Cuthbert, Wakefield

Thanks to this store I can enjoy an excellent mobile signal!

The manager of Mobile-signal-boosters.co.uk was the one who persuaded me that my problem can be solved and helped me choose the suitable repeater model. I also received all the answers to all the questions that I had about signal repeaters, even the most obvious ones. The manager was quick, polite and very helpful. I’m really happy with my purchase from Mobile-signal-boosters.co.uk and enjoy a comfortable life with good GSM and 4G signals.
