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.

Great for our vacation home
This was the best experience I ever had working with a support team. They helped me choose the model, provided detailed instructions on the installation, and as a result I managed to set up the booster without a hitch. The device has a handy LCD for convenient installation and easier troubleshooting. Finally, the mobile reception at our vacation home is stable.
Hello Jacob, we are glad to receive your feedback. Looking forward to your next visit, the team of Mobile signal boosters.

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.
· Daniel D. · Verified Buyer · 23-03-2023
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.
· Adam Kennedy (United Kingdom) · Verified Buyer · 22-03-2023
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.
· Angela (Germany) · Verified Buyer · 22-03-2023
It was a bargain!
I got the booster on sale and managed to save money. This was a very cost-effective solution for my family. The device works smoothly and we really like it!
Hi Angela, thanks for the review. We are glad to hear that you are satisfied with the purchase. Wishing you all the best, sales team.
· Tom A. (United Kingdom) · Verified Buyer · 16-03-2023
Better than I thought
I had used one booster before, but it was an absolute failure. This one is okay. Amplifies signal well, without any difficulties. 4G is stable, connection during the conversation isn't interrupted by noise.
Dear Tom, thank you for the review. We would be glad to see you at our store again. Kindest regards, sales department.
· Zach Whittle · Verified Buyer · 16-03-2023
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.
· Girard Morel (France) · Verified Buyer · 15-03-2023
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.
· Emma (United Kingdom) · Verified Buyer · 14-03-2023
Effective both for GSM and 4g
I have no complaints about it, as the booster is effective for both call amplification and stabilizing the mobile internet. The shipping took three days, all the necessary cables and accessories were sent together with the booster box.
Dear Emma, thank you for sharing your opinion. Looking forward to your next visit. Regards, the team of Mobile signal boosters.
· Isabelle Relish · Verified Buyer · 08-03-2023
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.
· Claude P. (France) · Verified Buyer · 06-03-2023
Good for thick walls
Our apartment is on the 19th floor, and the signal inside was poor because of the thick walls of the building. Communication was available only near the window, there were constant breaks inside the apartment. I purchased this repeater and was surprised at its effective functioning. However, it is very important to maintain the separation between the outdoor antenna and the indoor unit.
Dear Claude, thank you for sharing your opinion. Please, feel free to contact us in case you need. Kindest regards, support team.
· Finn M. (Germany) · Verified Buyer · 27-02-2023
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.
· Lily MacQuoid · Verified Buyer · 22-02-2023
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.
· Charlie · Verified Buyer · 22-02-2023
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.
· Nick (United Kingdom) · Verified Buyer · 17-02-2023
Improved weak reception
I wanted to improve both calls and awful 4G, therefore, I’ve chosen LCD400-GSM+4G booster. It’s okay for my house, which is about 400 m2. The reception has been improved from 0-1 bars to 4 stable.
Hi Nick, thank you for the review. We are glad to know that your problem has been solved. Regards, sales team.
· Dan (United Kingdom) · Verified Buyer · 17-02-2023
Doesn’t cover all the rooms
We installed the booster in our mansion, but to tell the truth, we are not 100% pleased with the result. The booster covers only one floor, and the level of mobile signal isn’t perfect around the whole building. I suppose that we should have chosen another model, with a larger coverage area or with the possibility to connect additional antennas.
HI Dan, we are glad to receive your feedback. This model covers areas up to 400 m2. Please, contact us, in case you need to exchange it. Wishing you all the best, sales department.
· Richard D. (France) · Verified Buyer · 15-02-2023
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.
· Tobias Fulberg · Verified Buyer · 15-02-2023
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.
· James S. · Verified Buyer · 10-02-2023
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.
· Jane (Ireland) · Verified Buyer · 10-02-2023
I’m pleased with the product. It boosts the signal well. The only issue is that the installation was a bit time-consuming and complicated for me. I had to contact the support team. They explained that the position of the outdoor antenna should be changed in order to be directed towards the nearest base station. We followed the instructions provided by the specialists and now everything is well.
Hello Jane, we are happy to receive your feedback. Please, feel free to contact us whenever you need. With best wishes, support team.
· Martin (Spain) · Verified Buyer · 10-02-2023
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.
· Mia Farah · Verified Buyer · 10-02-2023
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.
· Oscar F. · Verified Buyer · 02-02-2023
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.
· Hans (Germany) · Verified Buyer · 28-01-2023
After having used it for a month already, I can tell you that it’s worth its money. In general, I don’t think that it costs a lot, I think that it’s affordable. The booster has shown good efficiency, it supports LTE amplification. The outside antenna is so small that it’s almost invisible on the facade.
Dear Hans, thank you for leaving your review. We are glad to know that you are satisfied with the result. Kindest regards, support team.
· Ava Li · Verified Buyer · 24-01-2023
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.
· George Smith · Verified Buyer · 07-01-2023
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.
· Francesca (Spain) · Verified Buyer · 02-01-2023
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.
· Ted Brooks (United Kingdom) · Verified Buyer · 29-12-2022
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.
· Aaron Bradley · Verified Buyer · 29-12-2022
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.
· Ross Edgerton · Verified Buyer · 23-12-2022
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.
· John E (United Kingdom) · Verified Buyer · 17-12-2022
Everything is OK
I’m satisfied with the order. This is the second time I’ve been ordering here. The connection is excellent with the booster. The seller is reliable and the shipment didn’t take long. The product corresponds to the description. Recommended!
Hi John, we are glad to receive your review. Keep on enjoying the stable connection! With best wishes, sales department.
· Rafi Baker · Verified Buyer · 06-12-2022
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.
· Paul (United Kingdom) · Verified Buyer · 06-12-2022
Needs adjusting the outdoor antenna
In order to fine tune we needed to adjust the outdoor antenna because there was no signal amplification. Thanks to the support team the problem was solved.
Hello Paul, thank you for leaving the feedback. Please feel free to contact us whenever you need. With best regards, support team.
· Clifford Burks · Verified Buyer · 12-11-2022
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.
· Saniya Mohamed · Verified Buyer · 10-11-2022
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.
· Richard (Ireland) · Verified Buyer · 07-11-2022
No interference with base stations
The model deserves respect! Thanks to the automatic adjustment of the signal level I don’t experience any interference with the base station. The signal is stronger now. All the members of our family finally got what they wanted for so long - stable connection free of signal issues.
Hello Richard, thank you for sharing your opinion. We are glad to know that your problems have been solved. Wishing you all the best, the team of Mobile-signal-boosters
· Monica Blanco (United Kingdom) · Verified Buyer · 03-02-2021
What an expensive device! I really don't understand why there is so much money to be paid for. It even doesn’t support 1800 Mhz frequency.
Appreciated Monica, thank you for the review. LCD400-GSM+4G model supports 900MHz and 2600MHz or LTE800MHz by your choice. Please, don’t hesitate to contact us in case you need help. Regards, support team.
With the help of Mobile-signal-boosters 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.Dan Bell, Aberlour
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.Frank Linscott, Yeovil
At Mobile-signal-boosters 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.Abbie Houle, Stockport
