How it works
1800 MHz Mobile Phone Repeater Nikrans LCD-400D has a high-tech and very pleasant design, moreover, it is very compact which means that it can be installed practically in every room even without being noticed. It has an extended coverage area. It gives you an opportunity to use this booster for houses, office buildings, shops and hotels with several floors. If the structure of the building where you need to improve mobile signal is too complex, you can use special splitters and additional indoor antennas (a standard set includes one antenna that should be used inside and one antenna that should be installed outdoors to catch at least poor signal of your carrier) which will guarantee better coverage in the rooms that are rather remote from the place where LCD-400D booster box is located.

Good for 1800 MHz band
I am 100% satisfied with the result. The signal on 1800 MHz frequency has increased a lot. We have stable 4 bars out of 5. The quality of the connection is very good. Perfect audibility and no interference during mobile conversations - this is just what I’ve been dreaming of. The coverage is about 4400 ft2, the amplified signal is equally distributed around the whole site. The product is definitely worth the money.
Appreciated Samuel, we are glad to receive your feedback. Looking forward to your next visit. Kindest regards, sales team.
· Jacob (Ireland) · Verified Buyer · 20-08-2021
The booster is okay, works well with no interference. The order was processed quickly and I really liked the fast shipping, just a few days and I'm enjoying perfect connection.
Hi Jacob, thanks for the review. We would be glad to see you at our store again. Best regards, support team.
· Julia (United Kingdom) · Verified Buyer · 15-06-2021
This booster is suitable for 1800 MHz. The coverage is enough for our two-storey building. In general, we haven’t noticed any drawbacks during the two months we’ve been using it.
Hello Julia, thank you for sharing your opinion. We would be glad to see you at our store again. Regards, sales team.
· Paul Williams (United Kingdom) · Verified Buyer · 10-04-2021
Doesn’t work with some UK operators
This device isn’t suitable for some UK operators, as it supports only 1800 MHz band. It’ll be okay for EE network, Vodafone, Virgin mobile and some others, but it’s absolutely useless forTalk mobile and Three network. Fortunately, I could exchange it for the one which was okay for me.
Dear Paul, thanks for leaving the feedback. Please, don’t hesitate to contact us in case you need help. Kindest regards, sales department.
· Leonardo (Italy) · Verified Buyer · 17-02-2021
With the moving to a new house, we faced a very unpleasant problem - the cellular connection in the new area was just disgusting. Installing this device in the attic in front of the window (this was the place where the cell phone showed at least some connection with the operator) eliminated the problem.
Dear Leonardo, we are grateful to you for the feedback. It’s great that your problem has been solved. Kindest regards, sales team.

100 out of 100
It was this model that I was going to buy myself and it was the model that the manager recommended to me when I described the situation to him (poor mobile coverage in the village house, insecure network signal, barely live Internet). I like the device. But be attentive this booster amplifies only one frequency - 1800 MHz.
Hi Lily, we are happy to receive your review. Keep on enjoying the stable signal. Wishing you all the best, the team of Mobile-signal-boosters
· Peter (Poland) · Verified Buyer · 26-10-2020
This model works only at one frequency - 1800MHz, so it’s not compatible with many European operators and it’s a pity as we often have guests from other countries. That is why I think that the model is clearly overpriced. I believe that it should be cheaper.
Appreciated Peter, thank you for the feedback. We offer the lowest price for this model at the market. Wishing you all the best, sales department.
I would like to thank the company’s team for a very polite and caring attitude. The manager helped me choose the model and explained everything concerning the operational peculiarities. Later the support team provided detailed consultation on the installation process. Thank you very much for the help!
Dear Sofi, we are glad to have been useful to you. Don’t hesitate to contact us whenever you need, the team of Mobile-signal-boosters.

May be quite complicated to mount
I managed to mount this device and its outer antenna on my own, without any help though it's not that easy as it may seem at first. I love when it happens, and I’m very happy that I manged to do it, because I don’t like asking for help.
Hello Karishma! We’re happy that you appreciate it so much. Best regards, Support team.
· My grandfather is happy · Verified Buyer · 08-01-2020
I knew that my granddad was having signal issues in his cottage, so I decided to buy him a repeater as a surprise. He actually found out I was buying it, but he’s very happy with how good his signal is now!
Hi Sammy, it’s great to know that your grandfather is satisfied with his booster! Best regards, Support team.
Imagine me – a person who knows nothing about electronic devices – being able to install the signal booster by myself. It was so unbelievably easy! Thank you, guys, for the clear instructions!
Hello Tobias! You’re very welcome. Please feel free to contact us in case of any other possible questions! Best wishes, Support team.

Safe for children
My two-year-old child threw the amplifier off the shelf. Luckily, it was made from light thick plastic and everything was great with my kid. In addition, the shell of the booster also remained unharmed through the height was about 1 m.
Hi Bryan, thank you for the feedback. That's great that your child was not injured. Take care, support team.
· Ruby Fisher · Verified Buyer · 26-11-2019
100% Worth Buying
This is a very good product. The company is reliable. They sent my order without delay. The package was a bit damaged but the device itself was okay. They even sent me a longer cable as I asked.
Dear Ruby, thank you for the review. Keep on enjoying it! Kindest regards, Support team.
· Max Martin · Verified Buyer · 18-11-2019
Good for a village
Believe it or not, but after I had bought this booster, all my neighbours did the same. We live in the village with poor mobile coverage and with this amplifier the quality of voice connection is much better, although not perfect.
Dear Max, thank you for the feedback. We are glad to know that you are satisfied with the product. Kindest regards, Support team.
· Peter Shepherd · Verified Buyer · 12-11-2019
This is one of the best boosters I’ve had. I’ve installed it in my supermarket where the signal was very bad. Now I have NO PROBLEMS with GSM anymore. It works smoothly, everyone is happy!
Dear Peter, thank you for the feedback. We are glad to know that you are pleased with the product. Best regards, Support team.
· George Croucher · Verified Buyer · 01-11-2019
Good Technical Support Team
I’d like to thank the company’s manager. The support team is very nice at the company. They politely answered all my questions and patiently explained everything. Good job!
Dear George, thank you for the feedback. We would be glad to see you at our store again. Kindest regards, Support team.
· Philip Madison · Verified Buyer · 22-10-2019
Had no manual in the set
When I received my order, I found no user manual in the set. Fortunately, the installation wasn’t complicated and I managed to find some tips on the set up on the Internet. But in any case, you should be more attentive.
Dear Philip, we are sorry that there was no manual in your parcel, you should`ve contacted us and we would have sent you a PDF version of the manual by e-mail. So, please, feel free to contact us in case you need any help. Kindest regards, Support team.
· Tina Stevenson · Verified Buyer · 09-10-2019
Solved my problem
This is my second booster. The first one I have been using at the office and this one was purchased for home, just because I cannot imagine my life without this device any more. The one I bought for work improves both GSM and 3G, so it cost a bit more than LCD-400D, which I’m using at home. LCD-400D solved my problem once and for all. I have never thought that it would be so easy to get rid of poor mobile coverage in the house and at the office. I recommend it!
Dear Tina, thank you for the review. We are happy to know that your problem has been solved. Kindest regards, Support team.
· Lily Marriott · Verified Buyer · 30-09-2019
Wide range of models
The company offers a huge variety of models with different working frequencies and indoor coverage. You can find a model to you taste. In case you don’t know what to choose, like me, call the support team and they will eagerly help you. I bought LCD-400D and I like it. The device is very simple in usage but at the same time it perfectly deals with its main task – the amplification of poor voice connection.
Dear Lily, thank you for the review. We would be glad to see you next time. Best regards, Support team.
· Richard Moore · Verified Buyer · 21-09-2019
I was gladly surprised by the caring service at the company. The manager was very polite and helped me a lot. He explained me that this model improves LTE only on condition that the user’s provider works at 1800 MHz frequency for data transmission. In all the other cases the amplifier would improve only voice connection and not the mobile internet. Thank you very much for assistance!
Dear Richard, thank you for the feedback. Feel free to contact us whenever you need. Kindest regards, Support team.
· Arthur Charleston · Verified Buyer · 12-09-2019
Good GSM booster
The booster is effective. I live in the village where the quality of mobile signal leaves much to be desired. So my children advised me to install a mobile phone signal booster. I’ve chosen this model with the help of the company’s manager. The specialist told me that this one would be the best for the house of about 400 m2. It enhances only GSM at 1800 MHz. This band is widespread among different providers, so the booster works not only with Vodafone network which I use, but with others as well. It can even improve LTE for the networks which support the technology at 1800 MHz. If I’m not mistaken, that will do for EE operator.
Dear Arthur, thank you for the feedback. We would be glad to see you at our store again. Best regards, Support team.
· Martha Hatcher · Verified Buyer · 03-09-2019
Improves only calls!!!
I bought this booster for my countryside house where my family and I spend every weekend. Be attentive, because this model is only for bettering GSM signal, so you won’t have improved mobile internet in the result, only voice communication. I have WiFi at home, so for me the internet access is not a problem. The house is located in a small village, in about 30 km from the city. The device works well. The signal has really become better with the repeater. In the rooms where I hardly had 1-2 bars, now I can enjoy full bars! I’m very grateful to the company for a high quality product! Wishing you prosperity and further success!
Dear Martha, thank you for the review. We are very glad to know that you are satisfied with the purchase. Kindest regards, Support team.
· Ella Livingston · Verified Buyer · 25-08-2019
Effective for EE
I recommend the product and the seller. The device works without any troubles, the managers are real professionals. Check your operator's bands as the booster doesn't support all of them.
Dear Ella, thank you for the review. This model supports only one frequency band so in order that it works properly it's necessary to know the operator's frequency. Best regards, Support team.
· Amy J. · Verified Buyer · 20-08-2019

I’m very grateful to the support team managers! They are very polite and nice. Guys provided detailed consultations about the available models and their features. Thank you very much!
Dear Amy, thank you for the feedback. We are happy to have been useful to you. Best regards, Support team.
· Leo MacDuff · Verified Buyer · 18-08-2019
The order was delivered very fast, for which thank you very much! The amplifier works great. The coverage area isn’t very large, but for a medium-sized apartment it’s enough. For a large country house or villa you may need another model.
Dear Leo, thank you for the feedback. Your opinion means much to us. Best regards, Support team.
· Ruby Audley · Verified Buyer · 16-08-2019
I bought it last year to replace the older booster model, which I had used before. In general, it’s not bad. Works rather well, though improves only up to 3 bars inside the building which is about 300 square meters. All the fixation elements and cables of the recommended length were included in the full set, so I didn’t buy anything extra.
Dear Ruby, thank you for leaving a review. We will be happy to see you again. Best regards, Support team.
· Jacob Nelson · Verified Buyer · 09-08-2019
Using the device leaves only positive impressions. First of all, I liked the result of its work – stable mobile connection, speedy 4G internet, and not a single dropped call. Secondly, the booster is compact and light, the size is 165x115x35 and the weight is about half a kilo. And finally, the price was very attractive and tempting. I will recommend this booster to all my friends who have the same problem as me!
Hi, Jacob! Thank you very much for the review. Your opinion is very important for us. Kindest regards, Support team.
· Jack A. · Verified Buyer · 06-08-2019
No more network problems
If you constantly suffer from signal problems and poor reception, this thing is what you need. My operator is EE so the device effectively boost signal and ensures stable internet connection. I have been using it since last year and I have had no signal issues since then. If previously I got nervous whenever I made or received a call - now I get 100% satisfaction from using my smartphone. The audibility is very good, there are no more disconnections during conversations.
Dear Jack, thank you for the review! We are happy to know that your problem has been solved. Best regards, Support team.
The assembling process of my LCD booster is the easiest device-related assembling process you could ever face. I easily did at by myself in a few very easy steps and it’s impossible to do anything wrong! I am very satisfied with the result and the fact that they put clear and detailed instructions into every package so that everyone can understand how to put the signal booster together.Thomas Marbach, Kirriemuir
Despite the fact that I have reasons to like my operator, I was stuck in the house with poor and interrupting signal, while I needed internet badly because I was looking for a job and doing freelance assignments at the time. Signal issues made my working process a lot harder and annoyed me really much, so I decided to change that and do something about the signal. My family said I should try to buy a signal booster.
I didn’t have to wait too long for my order to arrive. Just as it was promised on Mobile-signal-boosters’ website, it was delivered to me very quickly – in three days. I wasn’t expecting it this early (and I totally forgot about the tracking number while being busy with other things), so it was a really pleasant surprise. All the parts that were needed to amplify my poor signal were already in the package.
