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.

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.

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.

Good home repeater

I took it to expand the signal in our countryside house. It’s so easy to use, I just plugged it in and it works without problems. I’m satisfied with the purchase. I think I will take one more for my office.

Hi Jacque, thank you for leaving the feedback. We would be glad to help you choose a booster for the office. With best wishes, 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.

Pleased with the product

I would like to thank the team of Mobile signal boosters for their service and high-quality product. The amplifier fully corresponds to the description and it works without any errors. The signal level has been increased.

Dear Peter, we are glad to receive your feedback. Your opinion is very important for us. Best regards, the team of Mobile signal boosters.

Inexpensive amplifier for home

We ordered this booster a few weeks ago. For so long we have had no problems with it. The device is working smoothly. We have installed it in the hall and the amplified signal is spread around the whole house without any disconnections. The booster isn’t cheap, but it’s at least inexpensive as the coverage capacity isn’t very large.

Hi Eric, thank you for leaving the feedback. We are happy to know that you are satisfied with the product. Wishing you all the best, sales department.

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.

Polite staff

When I was choosing this repeater, I spoke with three operators on the phone and asked many questions online. I want to thank you for the patience and polite attitude of each employee of your team. Keep on doing such a great job!

Hi Cortney, thank you for such nice words. We always try to make our service as great as possible. Best wishes, Support team.

It's suitable for crowded places

I'm the manager in a bank branch and this model has been recently installed in my branch because the 3g Internet or stable cell-calls were impossible due to the bank's location which was a great issue for both customers and my employees. I was impressed when I saw enough quantity of bars on my mobile phone and I'm thinking of buying the same model for my flat. Moreover, I helped to install the components, which was too easy, and I'll repeat it at home. Fortunately, today I can avoid unpleasant situations with clients and I don't need to explain the reasons for poor reception. Excellent!

Hi Robert, thank you for the review. We are happy that the booster could help you. Best wishes, Support team.

Okay for 900 Mhz

I recommend you to install a special smartphone application and to check the working frequencies of your operator and the level of existing signal in advance. In particular, check the quality of the network at the place where you plan to mount the external antenna. I took the booster to amplify 900 Mhz frequency in the cafe. It’s located in the basement in the city center, and the reception is very poor inside the building. Although I didn’t expect it, the connection became better with the booster.

Hi Alberto, thank you for the feedback. We are glad to know that you are satisfied with the result. Kindest regards, support team.

Works with all UK providers

I have this booster in my small shop and it works perfectly. Amplifies signal for all Uk providers and ensures stable connection. Recommended!

A lightweight

I am fond of the size and weight of this device. I had to arrange delivery to my mother's house and I was afraid that it would be too heavy to transport it to my place. Luckily, I was mistaken and even used public transport.

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.

Good quality

I appreciate the quality of each component in the kit. The booster was made from durable plastic, the screws and nuts were reliably tightened. I couldn't find any defects anywhere. Moreover, it was quite easy to connect cables with antennas and a booster box after which a device worked immediately automatically setting all the necessary options without manual intervention. I am going to buy the same one for my cabin located outside the city in the rural area among the trees.

Hi David, thank you for the review. We are glad you are satisfied with your amplifier. Best regards, Support team.

Simple functionality

I like it because I don't need to remember where the buttons are placed and how to turn on/off the booster every time. Ant it independently regulates the signal in connection with the emitting waves from cell-towers, so it's not necessary to interfere in this process.

Hi Kevin, we are grateful you've chosen our booster. Best wishes, 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.

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.

A reasonable price

I recommended this booster for my friend because it's worth the money I paid for the purchase. This thing is quite affordable taking into account the functions, which are able to carry out. It positively influenced the quality of conversations and 3g connection at home and I don't have to catch them around my apartment anymore.

Hi Trevor, thank you for the feedback. We hope that our device will please you for a long time. Take care, 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.

This booster permanently was installed in my apartment. However, sometimes I take it with me when I'm staying in a cabin for several weeks because it's capable to enhance a 3g signal and make cell phone calls continuous everywhere.

Hi Marshal, thank you for the feedback. You can find other amplifiers on your website. Best wishes, Support team.

Great for bars

I'm the owner of a bar in the building with thick stone walls in the basement. Last month a purchased this model because I'm tired of listening to complaints from customers about the poor reception of at least 3g Internet as well as about how it's difficult to make a phone call staying in the bar. I googled and found this repeater the delivery of which was organized for three days. Moreover, it was delivered to my bar and the installation process took only several hours. Then, I amused that the signal was improved not only inside the place, but it was covered the entrance as well. And there is one more thing I like. The amplifier's work doesn't greatly affect the amounts of payments in monthly bills.

Hi Ken, thank you for the review. We are happy you could solve your problems with a signal. Best wishes, Support team.

Wide coverage

My parents bought the model for our villa last month. It's worth to mention that it significantly improved the signal reception all over the place when before we had some trouble in the garden and a swimming pool area. That's amazing we could watch movies in the yard online using a huge projector. It seems life has become more fascinating and we even could comfortably organize a party some weeks ago.

Hi Olivia, thank you for the feedback. We are pleased to be able to help you. Best regards, Support team.

Case Studies

One day I typed in “signal boosters” quite hopelessly, and Mobile-signal-boosters 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.

Phil Broad, Manchester

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.

Norman Wheely, Aylesbury

The manager of Mobile-signal-boosters 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 and enjoy a comfortable life with good GSM and 4G signals.
