For more than 10 years, our boosters have been helping people in the UK, European Union, Asia, and Africa to successfully solve their mobile signal issues. We are doing our best to follow all the latest tech trends to meet the demands of users in different regions.

Choose the most convenient way to communicate with our experts.


Nikrans LCD-300GD is the next generation, latest booster equipped with the most advanced wireless technology to amplify signals. This particular model is developed mainly for improving GSM at frequencies of 900 MHz and 1800 MHz simultaneously, both being the most common in the United Kingdom and the rest of the world. 900 Mhz is widely used for transmitting 3G signal as well, so this model may serve as a 3G booster. 1800 Mhz is mostly considered supplemental, but in some areas, it is the primary GSM frequency operated. Moreover, it is often used for transmitting 4G. Consequently, the dual band amplifier will work best for smartphones running on both frequencies. With a built-in LCD screen, it shows system diagnostics such as signal level, setup recommendations, error notifications, power management and ALC data. Hence, it becomes easy and effective for novice users to use this device.

Since it is an upgraded model of previous versions, it now covers areas as large as up to 3200 ft² (300 m²). Ideally speaking, this coverage is sufficient enough for providing uninterrupted connectivity in shops, restaurants, cafes, basement offices, and even big apartments.

Home Mobile Phone Booster Nikrans LCD-300GD is the most cost effective and reliable booster that you can use to improve your network coverage. Here are some additional features of it:

  • LCD display. An LCD display is helpful for both novices and experts. It improves user experience and provides several notifications about the device such as installation steps, antenna gain and more.
  • Sleep mode. When the booster detects no incoming and outgoing traffic, it automatically switches to the sleep mode.
  • Automatic signal control function. When network reception is poor, the booster automatically adjusts gain levels.
  • Compact size and light weight. This Nikrans booster is designed to be compact, stylish and lightweight, making it easy and portable to displace around.

LCD-300GD signal amplifier provides uninterrupted voice calls alongside stable GPRS and EDGE networks. The device has passed all stringent European safety tests and obtained CE and RoHS certificates that proves its 100% safety for usage. It does not emit harmful radiations.

Order the dual band amplifier now and talk to your loved ones without any network issues.

How it works

It is recommended to use Home Mobile Phone Booster Nikrans LCD-300GD for small-sized buildings and apartments as it has a coverage area of around 300 m² (3200 ft²). In case you are interested in a cheaper model with shorter coverage, check out LCD-500GD GSM signal amplifier for Italy.

The booster has a booster box, two indoor antennas (for better rebroadcast of the enhanced signal over the premises), one outdoor antenna and necessary cables. The installation process is quite straightforward and doesn’t require any specific skills. But it is important to install it in a right way.

The best location to install an outdoor antenna is a roof (if there is no such an opportunity place it outdoors at you window). It should be aimed away from the building. The indoor ceiling antenna can be fixed, for example, on the first floor, in the basement or in the part of the building where the amplified signal rebroadcast by the whip antenna may not reach.

Good service

This is the best team I've ever worked with. The managers are so polite and patient. They helped me choose the right model and later gave instructions on the proper installation. Well done!

Dear Billy, thank you for the review. We appreciate your opinion very much. Wishing you all the best, support team.

Better than expected

I was hoping that the booster will help me get at least a couple of extra signal bars. Turned out it gave me three, and now the internet speed is flying, the connection is amazing all around our family house, and everyone is happy. What I like about this booster is that everyone can use it at the same time – great for big families where everybody wants to do their stuff in the free time. We surely enjoy it. It’s also really compact and didn’t affect our interior design in a bad way, and there are very few wires that don’t make an unaesthetic mess. It arrived to our house really fast and the packaging was good – that’s another good thing. But, I guess, the only thing it was actually supposed to do is to amplify the signals, and it does its job really well. We don’t have any problems with internet speed or GSM calls quality anymore.

Dear Yvonne, thank you for your positive review! It’s good to know that out booster helps your family so much. Best regards, Support team.

Fast shipment

I was gladly surprised to receive the booster earlier than the supplier had promised. The product was well packed, all the items for installation were included. We’ve already tested the booster and we can tell you that this is the best device of this kind that we have ever had.

Dear Fred, we are glad to receive your review. Keep on enjoying the stable connection. Best regards, support team.

I had to move the antenna around my roof and point it into several directions for a little while before I got the best result out of it, but it’s still worth it. My husband was helping me out with the antenna and the mounting, and eventually we did it. I didn’t believe that the signal in my area can be so clear and good, both the internet and the voice calls. I’m not disappointed in this booster at all.

Hi Bethaney, thank you for your feedback. We’re glad that you got such amazing results with our product. Best regards, Support team.

Better than my previous one

I previously bought a booster from another company, and I didn’t like the way it worked. It wasn’t amplifying the signal too well, and sometimes wasn’t working at all. I was obviously unhappy, and later decided to get this one. And it worked as expected. I really like it. I bought it two weeks ago and I already see a huge difference between what the previous booster did and how this one works. I recommend it.

Dear Dylan, it’s good to know that your booster works that well and you’re satisfied with your purchase. Best regards, Support team.

Effective Device

The booster is very effective. It works without any problems and errors. I also like its design as it doesn’t occupy much space and is very compact.

Dear Harry, thanks for your opinion. We are glad that you liked the purchase. Best regards, Support team.

Best price

I have spent a great deal of time trying to find it cheaper and I failed. Mobile-signal-boosters. offers the best price for this booster, and they have a huge discount. I’m so happy that I have purchased my booster here at a low price.

Hi Angela, thank you for the feedback. Keep on enjoying the product! Regards, the team of Mobile-signal-boosters.

Great Device

I´ve bought it to improve imperfect mobile signal at home. It easily covers the area of 250 m2 and works rather smoothly. The installation didnt cause any difficulties. In general, Im satisfied.

Dear Alan, We are glad to know that you are satisfied with the purchase. Best regards, support team.

Good for improving calls

Amplifies calls well. I think that this is one of the best amplifiers for GSM, as it’s cheap but powerful. The level of signal is much stronger and the audibility is good. There are no more interruptions, disconnections. I think that if you need to improve only voice connection at home without mobile internet, this is the most suitable variant.

Hi William, thanks for leaving a review. Your opinion is very important for us. Regards, sales team.

No More Signal Problems

I am a novice in this field, but I can tell you that this device really works. After it installation I have no signal issues, the reception is stable without any interruptions. Don’t hesitate to buy it!

Good Repeater

What I liked the most about this model is that it provides error notifications and recommendations via LCD screen. I am satisfied with the level of signal I have at home now. Recommend it!

Super compact and super effective!

The booster is very compact. It occupies minimum space in the house. The result is great, I have stable 5 bars around the house, wherever I go, upstairs, downstairs, in the kitchen… Just everywhere!

Dear Andrew, thank you for the feedback. We are glad to know that you are satisfied with the result. Best regards, support team.

Acceptable quality

The product is of an acceptable quality, although I can’t say that it’s 100% what I expected. The set included the booster box, which actually seemed a bit outfashioned to me, antennas, cables, and a manual. In general, it works without errors.

Dear Julia, thank you for leaving a review. We would be glad to see you at our store again. Kindest regards, sales team.

Good for Medium-sized Premises

It was a very lucrative offer, as Ive bought it with great discount. Its suitable for medium-sized premises. I use it to improve GSM and 4G, but it can be used for 3G amplification as well. Both calls and mobile internet are of satisfactory quality now.

Dear Oliver, we are happy to know that your signal has changed for the better. Best regards, support team.

 ·   ·  Verified Buyer  · 

Mostly works

I wouldn’t say that the booster gave me an excellent reception, but it works. We had a very weak signal at our house, from one bar to no signal at all, and with the booster we have 2-3 bars in most of our house. It’s better than nothing, and I’m okay with having a much more stable signal. The issue is probably in the surroundings of our house, which is a forest with a massive water body not so far away, and the cell tower is further down the road to the city. The booster was really as easy/quick to set up as it’s advertised, I could do it myself, no professional help needed. Overall, I’d say that it’s good.

Dear Dana, we’re sorry that the booster didn’t work out as well as you expected. Please contact us so that we can give you some advice. Best regards, Support team.

I’m not a professional in mobile boosters, so I just chose the one which looked nice and amplified my operator's frequency. It works well. Can’t tell you anything about the installation, as my neighbour did everything instead of me.

Hi Thomas, thanks for the review. We would be glad to see you again. Regards, sales team.

Good model

I’ve been using this device for two weeks and I can tell you that it’s worth its money. Unlike previous models, this one has a special port for an additional indoor antenna, which is undoubtedly a great advantage. I’ve installed this additional antenna and as a result we enjoy much better dissemination of the improved signal around the whole house.

Dear Miguel, we are happy to receive your review. Keep on enjoying stable signals! Regards, sales department.

Truly advanced device

I have finally found what I needed! With this booster I can use voice communication normally, and the Internet speed has increased dramatically. Everything is fine, I haven’t found any flaws.

Works perfectly

I’d like to leave this review and to tell the world that this is a fantastic device! It works perfectly, without any interruptions, errors, disconnections, etc. I recommend this booster to everyone who constantly suffers from signal problems. I used to feel the same and now I enjoy full bars!

For all providers

I thought that I would hardly find a device that would be compatible with all UK networks. Fortunately, I was mistaken. This model is a revolutionary one, I would say. It improves signal for all providers, although not equally well. But I think this is because of the difference in the existing level of coverage. In any case, this is the best thing I've ever seen!

Dear Mike, thank you for your feedback. We are glad to know that you are satisfied with the result. Wishing you all the best, sales department.

This was the first time I bought a repeater and I immediately fell in love with this model. With the built-in LCD screen its usage is as simple as it gets as well as the installation.

Improved signal

I didn't think that this booster would really amplify the signal to stable 4-5 bars. However, it did! The connection is very good now. We have no signal issues, reception is stable in all the rooms. I can't say anything about the installation because I had it set up by a technician, but I think that it isn't too complicated.

Compex installation

The LCD screen is so useful

Devices with the LCD screen are often times better than the ones without it. At least for me. I always want to know what’s going on, and now I do. The installation guide on the screen was great, because I hate reading off paper and my eyesight is poor. It also helps a lot that the screen is bright and can be clearly seen. But that booster doesn’t just stand there with its screen, it works, and it works well. I like my new signal quality and I start forgetting about how bad it used to be, which isn’t a bad thing, I suppose. No more issues with phone calls or inability to watch high-quality Youtube videos on my phone.

Beyond My Expectations

I bought Nikrans LCD-300GD cell booster to amplify poor signal at home. If I have any regrets they are about why I haven’t installed this wonderful device earlier. Great purchase!

Good standard set

I was glad to discover that the order included everything necessary for the immediate installation. The cables for the antennas were of good length, the one for the outdoor antenna was even too long, 20 m. All the mountings were reliable and in the necessary amount. The order was well-packed and arrived on time.

Lister Fantastic

Since I’m not a city dweller, I always thought that I’m destined to have bad signal and that’s the price I pay. But after I heard about signal boosters, I decided to give it a shot. I really like how it works, the signal is now fantastic, and I really enjoy my internet connection and cell phone reception now. The tech support is very friendly and well-informed as well, and they helped me out a lot.

Got rid of my signal problems

I used to go outside of my house or onto the balcony to text and make important calls. Now I don’t have to do this anymore, and honestly - it feels great! I moved into the area a couple of years ago, but the signal didn’t get better, despite my attempts to contact the operator, so I decided to buy a repeater and forget about these problems. And it worked! The connection is much better now, and I’m able to be online and available all the time.

Hello Lester, thank you for the positive feedback. We’re happy that you don’t have any signal issues anymore. Best regards, Support team.

Tempting price

I’ve spent quite a lot of time trying to find the same booster at a more profitable price, but I wasn’t successful. You won’t find it cheaper than here. So I bought this booster, and I don’t regret it at all.

Appreciated Tony, thank you for the feedback. We offer the lowest price at the market. Best regards, sales team.

A great model

This booster model is a good option for cafes and other places like these. I have ordered it to install it in a coffee shop, and it works fantastic. It amplifies every possible kind of signal and works with all local operators, which is great both for the staff and for the visitors. Now we actually have more clients then we did when we had signal interruptions, because people want to come and stay and they post pictures of our coffee shop online. So it was also a good business decision in the long run. I would recommend doing this to anyone who wants an income increase and who wants their employees to have good working environment, of course. Another good thing is that the booster arrived really quickly and we didn’t need to buy any additional parts for it. It was a one-time investment that brought really good results.

Dear Stacy,e we’re glad to hear that our booster helped your coffee shop and your customers so well. Best regards, Support team.

Good booster and good customer support

I had no idea how to choose boosters, so I had to turn to the customer support for help, and they didn’t disappoint me at all. I really liked the way they handled my situation and offered me the good suitable model that I use in my shop without any problems for three months already. I wanted to wait with the review because I thought I need to check it out for a little while, and no problems occurred during this time. The booster works well for GSM, 3G, and 4G signals, and the connection is stable all the time. I really like it and I think it was a good purchase that was worth it. Would recommend.

Improves signal well

This is one of the best signal boosters I came across on the internet. It really improves the connection and does it well. And the price is affordable.

Higher signal level

Amplification in the desired frequency range is noticeable, the level of mobile signal has become higher and more stable. However, the amplifier is sensitive to the presence or absence of any interference. Works 24/7, we don’t turn it off even at night, because I know that it’s absolutely safe.

Dear Jonathan, thank you for the review. We are glad to know that you are satisfied with the result. Kindest regards, support team.

Case Studies

The package from Mobile-signal-boosters’ store arrived so fast that we didn’t even expect it to be at our house yet. After we opened it, I was pleasantly surprised with the careful way it all was wrapped. Every detail was there (the booster box, two antennas, power source and wires), new and intact, and the user guide clearly and simply explained the assembling process, that I had no idea what to do about.

Edwin Ploss, Merthyr Tydfil

We actually spent some time on mounting the outside antenna on the roof of our house and making it face the side that was opposite of the hill that interrupted our signal, but otherwise, the installation process was extremely fast and easy. All we had to do after that was to connect this antenna to a signal repeater where I had already plugged the inner antenna, and then plug it into the power socket.

Iain Mackintosh, Pitlochry

I find it a very memorable thing that soon after I switched my Mobile-signal-boosters booster on, the phone inside my pocket buzzed. It finally received a message, because the signal inside my cabin became stable and good. It was very unusual to see the working signal (four signal bars on my phone and more) at this place. The booster was actually working very well, amplifying this so very needed BT Mobile signal.
