How it works

Each 4-Band Signal Booster Nikrans NS-300-Smart is composed of a mobile signal booster box, an inside antenna that is to be connected to a booster with a coaxial cable and an outside antenna that should be connected to a device with a cable as well. The standard length of the cables is 5 and 10 meters respectively. If such a length is not enough for you given the specificity of your house, you can always order an additional cable of the appropriate length. But please, bear in mind, that if the utilized cable is longer than it is needed, it may have a negative impact on the performance of your mobile phone signal repeater. Don’t use the cables that are not approved by the manufacture of the device.

The above mentioned model suits for EU networks only, and for the USA you need another booster type, e.g. cell signal repeater LCD-5000-CPA for all US networks.

Top notch quality

Amplified the signal better than any other device I had. The plastic is very durable and reliable. Everything is clear about the installation and the operation. The menu is very simple and I can navigate it intuitively. As for the downsides, then, perhaps, there is only one, and this is the price. But it seems to me that it is 100% justified.

Dear William, thanks for the review. We are glad to know that you are satisfied with the product. Kindest regards, the team of Mobile signal boosters.

Best investment ever

Don't be afraid of the high price, this device is going to be your best investment!I was hesitant for more than a month whether to buy it or not for my office. The quality of mobile connection was awful in our real estate agents' office. Then one day I decided to take a risk and I don't regret it! The reception is super stable, all staff can work without any fear of being disconnected during an important call. Sales went uphill and it's great!

Appreciated Nick, we are glad to receive your feedback. Wishing you further prosperity and success. Best regards, the team of Mobile signal boosters.

Good service

I'd like to thank the team of Mobile signal boosters for their perfect work. They timely answered my request for additional information and helped me choose the right booster for my business. It was a real pleasure to work with them. Their product fully corresponded to the requirements and the company provided all the necessary warranties and manuals. Thanks a lot!

Dear George, we are grateful for your review. Thank you for choosing our service. Wishing you all the best, the team of Mobile signal boosters.

Four months of connection without problems

I bought this booster in December last year. I decided not to write about my impressions right away, in order to have an opportunity to test its work, to evaluate all the possibilities. To cut a long story short, I am convinced that the mobile network is many times better with the booster than without it. We have had no signal problems since we installed it.

Dear Giovanni, thank you for the review. We are happy to know that your connection problems have been solved. Kindest regards, support team.

Strengthens signal

We haven’t installed it at the sight yet, but we have already tested it. The signal is improved by the booster noticeably. Some issues still exist but I think that they are more likely caused by the location of the base station and the peculiarities of the building rather than by the booster quality.

Appreciated Nick, thank you for the review. We are happy to know that the booster works well. Best regards, support team.

Short cable

Everything was okay except for the length of the cable for the outdoor antenna. 10 meters wasn’t enough for our place to place the antenna on the roof. We had to order some cable additionally.

Hello Sarah, thank you for the review. We have the possibility to customize the order at our website. Best regards, support team.

Worth its money

First I thought that the booster was too expensive, but when I had installed it and had seen the result, I changed my opinion. I’ve completely forgotten what poor mobile coverage is thanks to this device. It’s compatible with any mobile operator and it improves any kind of signal. What could be better?

Appreciated Lucia, we are happy to know that you liked the product. Keep on enjoying it! With best wishes, sales team.

Super Useful

The booster is penta band, so it works at 900 and 1800 MHz for GSM, 2100 MHz for 3G , 800 and 2600 MHz for 4G. Improves all types of signal, and does it rather well, even better than I expected. The working principle is simple and understandable. You only have to find the best place for the outdoor antenna and you are sure to have the result. If it still doesn’t catch any signal, just change the position of the outdoor antenna.

Hi Rodrigo, thank you for leaving the feedback. We are glad to know that you are satisfied with the result. Best regards, the team of Mobile-signal-boosters

Multifunctional amplifier

It’s cool! You can use it to amplify all types of signal at five frequencies! The most multifunctional amplifier I’ve ever seen!

Hi Patrick, thanks for the feedback. We are glad to know that you are satisfied with the product. Kindest regards, support team.

Perfect gift for parents

I bought this booster as a gift for my parents. They had poor mobile signal in the village house, and I decided to help them somehow. They really liked the device. The booster improves mobile signals at five frequencies - 900 and 1800 MHz, 2100 MHz , 800 and 2600 MHz - so it amplifies GSM, 3G and even 4G.

Hello David, we are happy to know that your parents liked the gift. Wishing you all the best, the team of Mobile-signal-boosters

Improves Everything

Believe it or not, but this booster really improves everything - GSM at 900 and 1800 MHz, 3G at 2100 MHz , 4G at 800 and 2600 MHz . As it supports five bands, it is compatible with any mobile operator. The only issue is that the outdoor antenna cable which went in the standard kit, was a bit short, so I ordered some extra.

Dear Brian, thank you for sharing your opinion. We appreciate it very much. Best regards, support team.

Powerful Device

One of the most powerful penta band boosters Ive ever met! When you look at its size you could never imagine that it is able to improve signal at five different frequencies simultaneously. I enjoy uninterrupted signal at home and the whole family is happy. Thank you very much!

Dear Kelly, thank you for the review. We are glad to know that you are happy about your purchase. Best regards, support team.

Great coverage now!

Purchased this device because we have an office in a metal building with a metal roof. We had zero cell service in the building. This came today and we immediately installed it. To our surprise all our smartphones have FULL signal. FULL! We were hesitant to order the booster after seeing some not so great reviews. But finally we decided to give it a try and it paid off.

Dear Marzena, Thank you for the feedback, it is very important for us. Kind regards, Support team.

Exceptional device!

I live in a rural area surrounded by hundreds of trees. When I moved in just over a half year ago, I could barely get a cell signal inside the house. I even switched providers hoping that would help. It didn’t. I had to stand by a certain window which is closest to the nearest cell tower to get at least 1 bar. My phone missed calls, delayed texts, can't download email, and can't be used for surfing the Internet. After the installation I can now use my mobile phone as "hot spot" for my computers and laptop. No more connection problems.

Dear Duncan, thank you for your feedback. Keep enjoying the booster! Best regards, Support team.

Lovely tech support managers

The tech support managers are very nice, polite, and well-informed. I had a lot of questions, I admit, and talking to them didn’t feel like they were forcing me to buy their stuff. Even though I ended up buying it eventually, haha.

Hi Hanna, and thank you for your nice review! We’re glad that we could help you with your signal issues. Best regards, Support team.

Not disappointed

I run a few internet speed tests when I bought it, and I can say that it really works. I tested it in practice as well, by using the internet and making phone calls, and I wasn’t disappointed in it at all.

Hi Alice! Thank you for this positive feedback. We hope you’re enjoying your stable signal with our booster. Best regards, Support team.

Requires no tech skills

I have literally no tech skills whatsoever, and I was able to install it and switch it on, and pretend that I’m savvy at this stuff. It tunes itself, and I don’t need to control it manually, and it survived an emergency power shutdown.

Hi, Kaleb! We’re glad that you like our cell phone signal repeater so much. Don’t hesitate to contact us if you have any questions about it. Best regards, Support team.

George Solis

The installation instructions are very clear and straightforward, which is a very important thing for me personally, and probably for those who are a little unfamiliar with the technologies as well. I managed to install it by myself and I’m enjoying the results. My indoor signal was almost nonexistent before, and now it’s half or more signal bars in every spot of the house. That’ s a brilliant improvement. No more lost connection or misheard answers on the phone.

Hi, George! Good to know that you’re enjoying using our product so much. We’re glad we could help you with your signal. Best regards, Support team.

Very convenient

I used to hate the signal inside my family house. I often needed to go upstairs and just sit on the stairs while talking on the phone, because I had nowhere else to sit and it was the only place with a decent signal. But when I finally ordered a signal repeater, the entire family thanked me. Now we can all use our phones for anything we want in separate rooms. It works even in the barn outside. A great device!

Hi, Fabian! Thank you for this review. It’s good to know that our product helped you improve your signal that much. Best regards, Support team.

A good solution for business

Having poor signal at the place that you own can influence the review and the business itself quite poorly. So when I decided to open a coffee shop in a business center, I researched the signal repeaters and went with this one. It’s really good, and I have zero complaints. As well as my clients. They’re mostly the business center workers, and they need to always be available. They can use the internet inside the coffee shop and make their calls.

Hi, Moshe! We’re glad that you and your clients are so satisfied with the signal quality achieved with this booster! Best regards, Support team.

Full bars

The device is effective. I enjoy full coverage in the office where I hardly ever had two bars. The closer to the indoor antenna I am, the better the reception is.

Dear James, thank you for the feedback. We would be glad to see you at our store next time. Kindest regards, Support team.

Prompt delivery

I was really surprised when a delivery boy knocked at my door in three business days because I counted to have a booster in at least 7 days. I like how swiftly you do your job. Keep up doing such qualified services!

Hi Jay, thank you for the review and for the nice words. We promise we will! Best wishes, Support team.

My choice

My sister recommended me your company for buying an amplifier. You have a very convenient interface with detailed information and descriptions about all models. I was easily able to choose the model without professional advice. Keep on going to do this nice job!

The best model

I had another model at my house I purchased from another company but it couldn’t solve the problem of a poor signal. Moreover, my basement has metal walls and it totally didn’t work there. But a friend of mine advised me to buy this booster and, luckily, it fulfills all the claimed characteristics. It’s very comfortable for me.

Dear Mary! Thank you so much for the review. We are glad to know that your issue was solved. Best wishes, Support team.

I finally found the proper model

This is the second booster I bought this year. The first one broke after a month of exploitation – the outside antenna was damaged because of a strong wind. So, I tried this model and it has still been working for 7 months. The quality of a booster box and antennas are amazing. Moreover, I am not afraid of a crash as the model has a 3-year warranty and it could be replaced if something happens. Finally, I’ve made a great choice!

Dear Jamie! Thank you for the feedback. We hope to provide high-quality services to our customers. Best wishes, Support team.

Powerful penta band booster

To start with, I’d like to tell you that this is my second booster bought here. The first booster I purchased here was for my house located in the mountains, the signal there was very weak, and now it’s good. This penta band booster I decided to order for my parents, who face the same problem. Initially they wanted a booster just for bettering GSM, but as my family spend time there as well, and we all use mobile internet, I’ve chosen NS-300-Smart.

Dear Ophelia, thank you for leaving the feedback. Keep on enjoying it! Kindest regards, Support team.

Ideal working range

This booster’s range is just perfect for the size of my cottage. I’ve had signal troubles before, but after buying the signal repeater, everything works well throughout my house. Very happy that I bought it!

Perfect for my cafe

This booster was installed in a small café that I own, and now we purchased some fancy backgrounds for Instagram pictures, and our clients love the café even more! They can post their pictures right there.

Dear Angelica, we’re really happy that your café is doing so well now with the stable internet signal! Best regards, Support team.

Excellent signal

Ever since I bought the Nikrans NS-300-Smart, every room of my house has high-quality signal. Even the bathroom and the basement. My kids are very happy, since the basement has always been their playroom.

Hello Zachariah! We’re happy that you and your family enjoy the good signal now! Best regards, Support team.

Case Studies

I would advise to choose devices offered by Mobile-signal-boosters as this company provides the full kit and you won’t have to purchase anything additionally. What is more, the shipping is very fast, for example, I received my order just in three days. As soon as I unpacked it I started the installation as I had everything necessary delivered in the set.

Tyler Dillard, London

Let me share my experience in using a signal booster. I purchased a mobile signal repeater at Mobile-signal-boosters to improve Asda poor signal in my hotel. The main reasons for Asda signal problems (and sometimes for other operators) were thick concrete walls of the building which didn’t allow the signal to reach people inside. I realized that I may start losing clients because of these inconveniences and decided to install a repeater.

Sean Sawin, Chelmsford

When you have to deal with mobile signal issues, you start looking for the reasons why your signal is imperfect. In my case, I couldn’t blame the operators as the problems were caused by the construction of the building itself. No matter how strong the signal was, it couldn’t penetrate through thick and massive walls. The only solution to this difficult situation was to install a signal booster, what I actually did.
