How it works

Thanks to its coverage and ability to improve several signal types, 4G & GSM Mobile Repeater Nikrans LCD400-GSM+4G can be a perfect variant for public places and office facilities, nevertheless, for large private houses it can also be a very good option. As the majority of other mobile signal amplifiers, this model has two antennas and one booster box. Among its main benefits that definitely should be highlighted, we need to name its LCD screen that will show you some useful data related to LCD-400-GSM+4G work, energy saving mode that will be switched on and switched off automatically without your help and automatically junction of signal level control and adjustment. As you may see this booster is really “smart” and can perfectly function without any efforts from your side.

The Nikrans brand supplies boosters worldwide, so there are models not only for the EU, but also for the US and Canada, e.g. NS-5000-Voice, 3G & 4G PRO cellular phone signal booster for all American providers.

Cool thing

This device is the coolest thing I’ve ever seen. But I think that it’s expensive. However I saw no other equal alternatives and I had to buy it. And actually I don't regret it as I’m pleased with the result. Voice connection is satisfactory and mobile internet is speedy.

Dear Girard, thank you for the feedback. We are glad to know that you are satisfied with the result. With best wishes, support team.

 ·  A (United Kingdom)  ·  Verified Buyer  · 

The signal has become better

Work stability has improved dramatically. I think that it’s worth its money.

Hello Adam, we are glad to receive your review. Keep on enjoying the stable signal. Regards, sales department.

 ·  M (Spain)  ·  Verified Buyer  · 

Unreasonably expensive

In general, it’s okay. However, the price for the booster is unreasonably expensive. The device is simple, and the price is too high for such a device. The antenna is made only in white, it would be nice to have one black or gray.

Hello Martin, thank you for the feedback. Your opinion means much to us. With best wishes, support team.

 ·  F (Germany)  ·  Verified Buyer  · 

I like it

I like the booster. It perfectly copes with its task. I have 4G/LTE signal where the phone itself didn’t see anything at all. The cables for the antennas are long enough. The device itself is very convenient.

Dear Finn, thank you for the review. We are glad to know that you are satisfied with the result. Kindest regards, sales department.

 ·  R (France)  ·  Verified Buyer  · 

With good features

I can call myself a real professional in choosing mobile boosters. My countryside house is located in the mountainous area, it’s a lovely place, but it has one disadvantage - the mobile signal there is awful. So I have had a lot of different mobile boosters, and I can tell you that this model has a number of advantageous functions in comparison with my previous ones. It has energy saving mode, automatic adjustment of signal. I like the design, and the size is compact. I recommend it to everyone!

Appreciated Richard, thank you for leaving the feedback. We would be glad to see you at our store again. With best regards, sales team.

 ·  N (United Kingdom)  ·  Verified Buyer  · 

Complicated but effective

A friend of mine gave me this booster as a present. I couldn’t make out how it works. Fortunately, the manager of the company helped a lot. However, I didn’t dare to install it myself. My neighbour did it for me. The booster works well.

Dear Nina, thank you for the review. Please, contact us whenever you need. Best regards, support team.

 ·  F (Spain)  ·  Verified Buyer  · 

Not ideal

I’ve been using this model for a month already, so I can share my experience. First of all, Id like to admit that its very compact and lightweight, so its easy to use and doesn't occupy much space. On the other hand, I cant call it an ideal device as it improves GSM signal at 900 MHz better than mobile internet at 2600 MHz.

Hello Francesca, we are glad to receive your review. Your opinion means much to us. Kindest regards, sales team.

 ·  T (United Kingdom)  ·  Verified Buyer  · 

Had some peculiarities

I installed the booster myself. Initially, when I plugged it in, it didn’t work. As it turned out later, I have chosen a wrong place for the outdoor antenna. When I contacted the support team, they explained that the outdoor antenna had to be placed in the zone where there was at least weak mobile signal. Only then will it be able to catch the imperfect signal and improve it. When I changed the position of the outdoor antenna, everything was okay.

Dear Ted, thanks for feedback. Please, dont hesitate to contact us in case you need help again. With best wishes, support team.

 ·  R  ·  Verified Buyer  · 


I chose this one because it was suitable for the frequency of both my and my wife’s operators (and it can be more difficult when you have two different ones), and because of its price. The price was probably the fairest one I’ve found. I loved how transparent the company policy is and how well informed the customer support managers are. They actually helped me find this booster model and asked all of my questions about payment and delivery. The content of the parcel was the same as advertised, all parts arrived without damage. I also need to say that I like how it works. My signal went straight up to 4 bars, my wife with a different operator now has 5, but I wouldn’t say that my connection or internet speed is worse. It’s stable enough for both of us. We like this booster and I think it’s safe to recommend it.

Dear Rafi, thank you and your wife for purchasing our product! We’re glad that you like it so much and it works well for you. Best regards, Support team.

 ·  I  ·  Verified Buyer  · 

Not cheap but effective

To tell the truth, my first impression was spoilt by the high price, but by the moment I have not found a cheaper option with the same characteristics. As for the booster itself, it works without any disruptions.

Dear Isabelle, thank you very much for sharing your opinion. Enjoy using it! Best regards, support team.

 ·  O  ·  Verified Buyer  · 

It Works!

I used to have almost no signal at the office and with this device I have a stable network without turns off. I am totally pleased with the result. The only inconvenience of the booster for me is however the necessity to fix the antenna outdoors which is not always easy to do especially if you rent an office.

Dear Oscar, thank you for the review. We are glad that you are satisfied with the results. Best regards, support team.

 ·  A  ·  Verified Buyer  · 

High quality device

I am really pleased with the services rendered by the company and the device itself. I had problems neither with payment nor with shipment. The repeater works very well and now we constantly have a stable signal.

Dear Ava, we are glad to know that you highly appreciated our services and products. Best regards, Support team.

 ·  T  ·  Verified Buyer  · 

This booster is good

I can’t remember the last time I had such a good signal. That was probably before I moved into my current apartment. However, I got tired of the signal issues and bought this booster, and now I know what it’s like to live without video buffering, lots of waiting until the page loads, and calls that sound like I’m in the woods. Now I can use not only the wifi at my university, but also the internet at home.

Dear Tobias, we’re glad that you don’t experience these signal troubles anymore. Thank you for the review! Best regards, Support team.

 ·  M  ·  Verified Buyer  · 

It gave me two more bars

Well, I can’t say that it works perfectly, but that’s probably just my location to blame. The signal is definitely better than it used to be, and after a lot of antenna tweaking I can say that +2 bars is most likely the best I can get out of it. I can use my phone and internet now in all of my rooms, and that’s better than what I had before. The signal is stable and never disappears anymore, which is good.

Dear Madeeha, we’re glad that your signal is better. Unfortunately, at some locations it’s impossible to get maximum signal, but we always aim at making it stable and usable for you. Best regards, Support team.

 ·  Z  ·  Verified Buyer  · 

Not bad

I was going to leave a more bitter review, because when I opened my package, I noticed the absence of one cord that was supposed to be there and was a necessary part. But after I contacted the customer support, they shipped me a new cord really quickly, so points to them for swift troubleshooting. The booster itself is not bad, so that’s my final review. It works and it amplifies my signal, making it 2-3 bars more than it used to be.

Dear Zach, we’re sorry for the inconveniences that you experienced. Thank you for leaving your honest feedback. Best regards, Support team.

 ·  R  ·  Verified Buyer  · 

All good

The shipping was really fast, I got to admit. I expected it to be there much later, yet here it is. Even when I haven’t switched it on yet, I already liked it just for the packaging. I’ve had a similar one before, so I knew how they work, however, the instructions for this one were clear and easy, and I managed to install it quicker. It amplifies the signal in my office room, and that’s exactly what I needed.

Dear Ross, it’s good to know that you like our product so much. Thank you for purchasing from our store. Best regards, Support team.

My kid likes it

I had no signal in two rooms of my house before, which were located near the east wall. When my kid grew aa bit older, he occupied this room, and he needed the signal to study and chat and do other stuff teenagers like. Me and my spouse decided to buy this booster because it was rather affordable, and we didn’t regret. The kid has no complaints about the signal strength, and other rooms now have better signal too.

Dear Toni, we’re happy that the repeater you bought at our store works so well for your entire family! Best regards, Support team.

Solved my signal issues

My house is made of wood, and the roof is definitely not metal, however, the signal had troubles getting inside of it. I have no idea why. So I needed a signal booster, and I decided to buy this one because of its working range and the signal types it works with. I’m not disappointed. It does what it has to do: amplifies the signal all over my place, supports multiple devices (even when my guests come over), and needs no attention. It adjusts itself, and it also switches off when it’s not needed. I also experienced no headaches or anything while it’s in the house, so it’s actually safe to use around people.

Dear Alena, thank you for leaving this review. It’s good to know that you’re satisfied with the booster that you bought at our store. Best regards, Support team.

Mounted it easily

I really appreciated that this repeater was easy to mount. It can be complicated for me to deal with technology, however, this was a piece of cake indeed. The display of the booster had the installation guide all along, and I also had the printed instructions in the package, and all I had to do was a few quick steps. Now my house has good 4G and GSM signal, and all of my family is really happy with it. My outer antenna is not on the roof, but on the outside wall near the window instead, on the first floor, but it works perfectly and I don’t need any further antenna adjustments, at least for now.

Dear Saniya, we’re glad that it was so easy for you to install your booster. Thank you for the positive feedback. Best regards, Support team.

A good decision for an underground office

I rented a small office in the underground premises for myself to run my business from there, since it was cheaper and I don’t mind it being underground. I didn’t need much space, just good internet connection and GSM signal. And there’s when I faced the problem, because the signal suffered in there. I liked the office, so I was considering the options on how to improve the signal, and chose this booster. And, eventually, it was a good one. No problems with installation, not much space needed, just a few wires. I simply put in on a shelf near the power socket, and it takes up very little space. I love how good the signal is now, and I can do all my business-related things without delays and failed calls. The booster eventually saved me money and helped my business, so I don’t regret spending my money on it.

Dear Clifford, thank you for this review. We’re glad to know that our product helped you and your business. Best regards, Support team.

Good device, which looks attractive and doesn’t spoil the interiors of my café. I managed to install it by myself. Now my visitors enjoy perfect coverage and fast Internet.

Dear Charlie, thank you for the feedback. We were happy to help you. Best regards, Support team.

 ·  D  ·  Verified Buyer  · 

Price is bit high

I completely agree with people, who say that the device is a bit expensive, but the price can probably be justified by the fact that it works without errors and ensures stable GSM and 4G around the area. I went from 1 bar in the house to stable 4.

Dear Daniel, thank you very much for sharing your opinion. It is very important for us. Best regards, Support team.

 ·  L  ·  Verified Buyer  · 

Good thing

It really enhances the level of mobile signal and as a result the speed of 4G Internet. This booster is a great thing for those who live in the countryside and in the areas with poor coverage.

Dear Lily, thank you for the review. Hope to see you at our store in near future. Best regards, Support team.

 ·  L  ·  Verified Buyer  · 

Good result

The results of using this booster for a weak are good. I can move around the house without being afraid to lose the signal. 4G connection is speedy and without any interruptions, voice communication is good as well though upstairs only 3 bars.

Dear Leo, thank you for the feedback and we are glad that the booster improved your communication. Best regards, Support team.

 ·  J  ·  Verified Buyer  · 

It’s worth its money

I used to get frustrated every time I needed to make a call or to surf the mobile internet in my office. After purchasing this booster the situation changed – I am always in touch as there are three-four bars on my phone constantly.

Dear James, thank you for the feedback. We are glad that you problem has been solved. Best regards, Support team.

Wide range of boosters

I bought two boosters here - LCD400-GSM+4G for house and another one with larger indoor coverage for my office (NS-2500GDW). I liked one more – a car booster. I think that I will buy that one as well.

Dear Mia, thank you very much for the review. We would be glad to help you choose a car booster. Best regards, Support team.

Couldn’t have been better

What a caring service! The specialists gave detailed answers to all my questions regarding the product and its features. This is the third time I have ordered from them and I’m sure that not the last one!

Dear George, thank you very much for your loyalty. We would be glad to see you again. Best regards, Support team.

Worked better than I expected

I purchased it for my summer cottage. As most summer cottages are, mine isn’t located too close to the city and the cell towers, so the signal was rather poor. And while summer cottages are for resting, not working, internet and phone calls are part of resting too, so I wanted a better signal to be in contact with my family and for entertainment. I didn’t expect the booster to work so well in this location and circumstances, but the signal is now better than I hoped for. Definitely a great device! Good for phone calls, videochats, even online games and watching youtube. Procrastination in the countryhouse, here I come.

Dear Aaron, we’re glad that our product has worked out so well for you. Thank you for leaving your feedback! Best regards, Support team.

Case Studies

Dan Bell, Aberlour

My EE signal problems are gone!

With the help of Mobile-signal-boosters.co.uk and their booster, my signal is now strong and my internet speed allows me to download anything, stream videos, listen to lots of music online and many other activities I now do from home. The signal is stable throughout my whole apartment, in every room, even in the bathroom and on the balcony! I am absolutely in love with what this signal repeater does and how it helps me.

Frank Linscott, Yeovil

All components in one package.

All the details that we found inside the package after its arrival, were very well-packed, of nice quality and all in their places where they should have been. The parcel has arrived very soon indeed, unlike it usually happens in lots of other online stores even if they promise the fastest delivery ever. Everything, including the cables, was already there, which was very time- and money-saving.

Abbie Houle, Stockport

Thу deviced saved our situation with Internet connection.

At Mobile-phone-signal-boosters.co.uk website we were recommended to buy the model that was ideal for the size of our office (we rent only one floor, but it’s quite a wide space), and was suitable for Freedom Pop frequencies and 4G internet. We didn’t have too much spare money, and the price of the booster seemed good. We were also fascinated by the promise that the signal repeater would be delivered in just several working days.
