How it works

Let’s have a look at the main working principle of LCD250-4G-D mobile signal booster. First, the outside antenna catches the existing signal and passes it over a cable to the LCD250-4G-D booster box whose function is to improve the poor signal. Next the refined signal travels over another cable to the inside antenna and is also caught by the whip antenna, both working to disseminate the strengthened signal around your house or office providing you with a usable indoor cell reception. The full set contains a manual with detailed installation instructions which will help you to set up the device on your own. In any case, don’t hesitate to contact us if needed before you proceed.

Good product

I’m satisfied with the product. The voice connection is stable now, there are no disconnections. I never miss calls any more. Is it effective for the mobile internet? Yes it is! And I’d noticed that the amplifier not only makes the connection more stable, but it also increases the speed of mobile internet.

Appreciated Bartek, thank you for leaving the review. We are happy to know that you are satisfied with the result. With best wishes, the team of Mobile-signal-boosters.co.uk.

Complicated to install

WE ordered this booster for our private house. We’ve checked the frequencies and the coverage area. Everything seemed okay, but when we installed the booster something went wrong. So we called the support team. The manager explained that we needed to change the positions of the indoor and outdoor antenna. He also explained that a lot depended on the nearest base station. Actually, we have a few of them and these base stations are loaded in different ways. The one that is closer to the private sector is loaded more, so we tried to connect to the other one. Now everything is alright.

Dear Adam, thank you for the feedback. Feel free to contact us whenever you need. Kindest regards, the team of Mobile-signal-boosters.co.uk.

Enhances reception

This is a useful thing. The reception was enhanced by 40% at least. Works with all UK operators, except Talk Mobile network.

Dear Charlie, thank you for the feedback. we would be glad to see you at our store again. Kindest regards, support team.

 ·  E (United Kingdom)  ·  Verified Buyer  · 

So expensive!

I like everything, except the price. In my opinion, it’s too expensive. As for the functioning of the device, I have no complaints.

Appreciated Edward, thank you for the review. We offer the lowest possible price for the product. Regards, sales team.

 ·  R (Greece)  ·  Verified Buyer  · 

Stabilized connection

My connection became twice better than I had had before. The Internet is speedy, all the mobile apps work smoothly. There are no more disconnections. I was trying to find it cheaper, but I couldn’t. So I think that it’s the best offer.

Dear Rafael, we are grateful for your feedback. Keep on enjoying your stable connection. Kindest regards, sales department.

Ensures 5-bar coverage

Good product. I have 5-bar coverage in the house now. When the weather gets worse the coverage may decrease a bit.

Hi William, thanks for the review. Keep on enjoying it! With best wishes, sales team.

 ·  K (United Kingdom)  ·  Verified Buyer  · 


I’ve chosen this booster on my friend’s advice and I don’t regret it at all. Pros - reliable device which significantly improves 4G for all UK providers, compact size, LCD screen, safety. Cons - haven’t noticed any yet.

Hello Kelly, thank you for the review. we would be glad to see you next time. Kindest regards, sales department.

 ·  J (United Kingdom)  ·  Verified Buyer  · 

More than I expected

I was a bit sceptical about this device, and couldn't believe that it would really change the quality of mobile signal at my apartment. And I was surprised when the level of mobile signal increased significantly with the booster. 4G is so speedy that I can watch live videos and make calls in Skype.

Hello John, thank you for the feedback. We are glad to know that you are satisfied with the booster. Regards, sales department.

Doesn’t improve 3G

I bought this booster to improve 3G connection at home, but as it turned out later, this model isn’t suitable for 3G signal amplification. This repeater improves GSM and 4G internet. I got in touch with the company, and they agreed to change the booster. They advised me the model, which boosts only 3G, as actually, my voice connection was ok. So, be attentive when choosing the model. If you’re not sure about the frequencies, its better to consult the manager.

Dear Angela, thank you for the feedback. We would be glad to help you whenever you need. Kindest regards, sales department.

No More Terrible Internet

My Internet at home was terrible! I could hardly open a light page in the browser, to say nothing of uploading or downloading any data. And now its so speedy! I can even watch my favourite shows live. That’s cool!

Hi, Clarke, its great that you are so happy with the result. We would be glad to see you again. With best wishes, support team.

3-4 bars at office

My office is located in an underground trading center just in the heart of the city. The mobile signal there was very poor, it was impossible to make calls and there was no mobile internet at all. I used to have only one bar, sometimes there was even no connection at all. I can’t say that the coverage now with the booster is perfect all the time, but at least I have 3-4 bars always. When the weather is bad it may fall to 2 bars, but still it’s possible to make and receive calls. 4G connection may suffer from time to time, but it happens very rarely. I think that I couldn’t have found anything better at this price.

Dear Olivia, thank you for the feedback. We would be glad to see you at our store again. Best regards, Support team.

Not suitable for 3g

I thought that I could use it for improving 3g, but unfortunately, I was mistaken. It turned out to be useless for 3g amplification, as it supports 800 Mhz frequency for bettering 4g/LTE.

Dear Irma, thank you for the feedback. Feel free to contact us and we'll help you in choosing the appropriate model. Kindest regards, Support team.

Big improvement in cell service

I have a detached building with a metal roof which I use for entertaining. But there were no cell service inside. I installed this booster in less than an hour and I not only have cell service, but internet connection as well. Bottom line - it's pricey enough, but if you have decent to good signal outside, but crappy signal inside, then this will really help!

Dear Richard, we are glad to know you are enjoying the amplifier! Best regards, Support team.

 ·  R  ·  Verified Buyer  · 

Affordable amplifier

After installing we saw immediate results. The phones were holding 3 to 4 bars 4g LTE over most of the house. This unit does the work well. I highly recommend this booster.

Dear Ross, we’re pleased that you are satisfied with the device. Kind regards, Support team.

 ·  R  ·  Verified Buyer  · 

To my happy surprise it does work

Installed this last month. I live in a pretty rural area and I had 1-2 bars of LTE service outside of my house, and No Service inside my house before this unit. Once the device was hooked up and powered on, I immediately went from No Service in to 5 bars of LTE coverage. The booster doubled the data speed I was able to download inside!The directions are pretty good and everything is pretty self-explanatory on the installation. The only tricky part of the setup was running the coax cable from the outdoor antenna into the house to the signal amplifier. Overall, I’m happy with this purchase.

Dear Rafael, Good to know that we could help you. Thanks and regards, Support team.

 ·  C  ·  Verified Buyer  · 

Bought as a present

I think that this is the best ratio of price and quality. I bought it for my friend, as a present. He is happy with it. He told me that the mobile connection at his house is very good now, reliable and stable.

Dear Clara, thank you for the feedback. We are glad to know that your friend liked it. Best regards, Support team.

Compact and Effective

A very simple booster but effective. It isn’t large, rather compact but improves signal easily and shows necessary information on the screen. I like it!

Dear Ben, thank you for the review. Enjoy it! Best regards, Support team.

 ·  G  ·  Verified Buyer  · 

Has LCD Screen

I have chosen this model because it has an LCD screen. In my opinion it’s one of the best models of new generation.

Dear George, thank you for the review, your opinion means much to us. Kindest regards, Support team.

Improves poor connection

The booster works well, without any interruptions. Improves weak signal significantly in my private house located in the village. The system consists of the booster box, two indoor antennas (whip and ceiling), an outdoor antenna and cables. The mountings and the user manual were included in the set as well. Actually, I didn’t like the colour of the booster box, it was black, but they had no other options available.

Dear Oscar, thank you for the review. We would be glad to see you at our store again. Best regards, Support team.

Good quality

Nice booster. I ordered it for my café, which is around 200 m2. The model has two working frequencies - 800 Mhz and 1800 Mhz for improving both GSM and 4G, so my visitors can benefit from both types of improved signal, although I have WiFi in my café as well. The model is compatible with all providers, which is a great advantage for my place as it’s often visited by tourists.

Dear Ron, thank you for the review. We are happy to be useful to you. Best regards, Support team.

I recommend

The support team helped me a lot to choose the amplifier, as I am not very knowledgeable in this sphere. The order was shipped immediately after we had clarified some issues concerning the coverage area and the operators we use. The delivery took five days. It was packed very well. When we received the product, my husband installed the repeater and now we enjoy stable mobile connection for all operators at home. We are very happy. The booster amplifies GSM and 4G, though voice communication is improved better than the mobile internet.

Dear Sophia, thank you for the feedback. We are glad to know that you are satisfied with the product. Kindest regards, Support team.

 ·  B  ·  Verified Buyer  · 

Everything is OK

I received the order yesterday and immediately decided to try the booster. The installation was a bit time-consuming but I decided to do it myself. The repeater amplified voice communication and mobile internet in all the rooms of the house. So it really can be used in the area of 200-250 m2.

Dear Bread, thank you for the feedback. We are glad to know that you are happy with your purchase. Best regards, Support team.

Short cable in the set

The booster itself isn’t bad at all. It works without any problems. The only issue was that the cable in the set, which goes with the indoor antenna, turned out to be too short for my place. Its length was 5 meters and I needed 7, so I had to buy another one.

Dear Dan, thank you for the feedback. Feel free to contact us whenever you need. Kindest regards, Support team.

Great device

This signal repeater works really well and amplifies the signal in my apartment. The store’s tech support is quick and friendly, they give you all the information, and they helped me a lot with choosing my repeater model. The packaging of the device is also great, I really enjoyed taking in out of the box, and all the details were intact after the delivery. It’s a great value for what you get in return.

Hello Dilara! Thank you for your review. We’re always happy to help our customers, as well as potential ones. Best regards, Support team.

This is my second booster. I have one at home, it’s a triband model. As for LCD250-4G-D, I installed it in the office to improve poor 4G/LTE. The device works well. The internet connection at work has become much better.

Dear Rob, that you for the feedback. We would be glad to see you at our store again. Kindest regards, Support team.

Case Studies

Sandy Everard, Welshpool

Excellent signal guaranteed!

EE’s tariff plan I was subscribed to was perfect for me and I never wanted to change that and look for another contract with another operator, even though signal issues at my apartment were driving me crazy most of the time. But when I heard of signal boosters and Mobile-signal-boosters.co.uk specifically, it has changed my life for the better and helped me receive strong signal without any issues and interruptions.

James Golden, Warrington

Easy to connect, great to use!

Assembling a signal repeater is really very easy and can be done in just a few steps – and I have experienced that myself. The only things I had to do was to place the outer antenna outside my window, then connect it to the booster box, plug the second antenna in, and then plug all the system inside a power socket – and that’s all! I am genuinely really impressed by how easy it turned out to be.

Victoria Trew, Galway

Very pleasant price range.

Mobile-phone-signal-boosters.co.uk is a helping hand given to anyone who’s in trouble with their signal and needs help. Their manager team are the politest and most helpful people ever, who were ready to answer all of our questions as soon as possible. They have told us about all the possible models we could have at the price range we wanted, and they helped us choose a perfect one. Their tech support is the best!
