NS-2500GD is a dualband 4G mobile phone signal booster that amplifies a mobile signal at two frequencies, 900 MHz and 1800 MHz at the same time, and is apt to drastically ameliorate the GSM signal reception of all the operators in the UK. Moreover, if your provider uses these frequencies to deploy its 3G/4G Internet network in your neighbourhood, you will get an added advantage of getting these signals of high strength.

It is effective for amplifying low signals in spacious areas that otherwise are not easily covered, such as giant shopping malls, offices, supermarkets, underground parking, and conference halls, etc. The maximum coverage area is up to 21,600 ft2 (2000 m2).

Here are some of the most important features of this booster:

  • Shut-off function is necessary for preventing repeater from getting damaged due to strong external signals or incorrect installation.
  • Automatic Level Control (ALC) is used to control repeater output signal for preventing network interference.
  • Automatic Gain Control (AGC) is useful to automatically control incoming signal strength.
  • Manual Gain Control (MGC) is meant for advanced users who prefer to regulate gains manually.

The compliance with the internationally recognised CE and RoHS standards ensure that the deivce is 100% safe to use and doesn't affect your health and environment. On top of it, you will benefit from a 3-year warranty.

Click on the "Buy Now" button andforget completely about dropped calls and slow Internet for good!

Some UK's providers also use 900 MHz frequency for 3G Internet connection. So if your mobile operator supports 3G at 900 MHz, this booster will improve both your phone calls and Internet connection.

How it works

4G Mobile Signal Booster Nikrans NS-2500GD is not just another powerful device, it is also a really smart one. While its task is to receive, boost and spread the signal, it can automatically control the strength of the signal that is caught as well as the level of the signal that is spread. These important features ensure the safest functioning of the device and its highest effectiveness. If a user has deep understanding of the working principle of the device and wants to regulate these settings manually, such an option is also available.

Shut-off function that NS-2500GD has helps to minimize risks of damages and errors that can be caused by mistakes in installation or too intensive incoming signal.

Reliable device

The repeater looks really reliable and trustworthy. The plastic is strong enough, however, I’m not sure whether it’s afraid or not of freezing temperatures, so, perhaps, it will be necessary to remove the repeater for the winter period, as it’s rather cold at our parking lot in winter. The power socket and the connectors for the antennas are also of good quality. The external and internal antennas are very compact.

Dear Robin, thank you for sharing your opinion. We are glad to know that you liked the product. Wishing you all the best, the team of Mobile-signal-boosters.co.uk.

Easy installation

The device is simple in operation and its installation wasn’t troublesome. Even if you can’t figure out how it should be from the manual, the Internet is full of videos with a detailed description of the installation process.

Hello Edward, thank you for the feedback. Feel free to contact us in case you need help. Best regards, support team.

Enhanced the level of signal

The device really improved the quality of the reception. It noticeably increased the speed of the internet connection. The cables were a bit short for my location, so I just changed them.

Hi Francesco, thank you for the feedback. We would be glad to see you at our store again. Wishing you all the best, the team of Mobile-signal-boosters

This dualband booster is the best one in my opinion. The main advantages are the following: it supports almost all UK providers, it improves all types of signal, it has a huge coverage area, and it’s very compact and nice. As for the disadvantages I can only name a complicated installation and short cables in the standard set.

Appreciated Jane, thank you for the review. Your opinion means much to us. Regards, support team.

The coverage is impressive

When I got this repeater, I wasn’t really hoping that it could cover that much space, but it really does. Its working range is huge, and it works in every room of my office building! Now we can have great signal everywhere.

Hi Luella, we’re very glad that it worked out so well for your office. Best regards, Support team.

I love the way it works

Never had any issues with this booster model! It’s perfect for any large place with lots of people, and it does its job brilliantly. No lost signal with either GSM or internet throughout the entire building!

Hello Phoebe, we’re very glad that you like this signal repeater so much! Sincerely, Support team.

Wayne Huang

Parents usually got bored at our entertainment center while waiting for their kids, so we decided to mount a signal amplifier. Now parents can use their smartphones inside the building, and it’s really appreciated.

Hi Wayne, it’s good to know that your visitors’ parents are now satisfied with the place, as well as the kids! Best regards, Support team.

Check your outdoor antenna

Pay attention to the position of your outdoor antenna. I first installed it incorrectly and the signal wasn’t improved. The outdoor antenna should be, turned in the direction of the base station.

Dear Bob thank you for the feedback. If you need our help, feel free to contact us. Kindest regards, Support team.

Stable 4 bars

This device really works. I installed it a week ago and since then I have had no signal problems in my place. The GSM signal is perfect, I have stable 4G/LTE. The signal never falls lower than 4 bars.

Dear Andrew, thank you for the feedback. Keep on enjoying it! Kindest regards, Support team.

I’ve been a client of this company for more than five years. They are real professionals and I like their client oriented approach and responsibility. They work directly with amplifier manufacturers, so I do trust them!

Good solution

I’ve read a lot of reviews about the high price for this booster, but I can’t agree with them. From my point of view, this is the best price at the market. Don’t forget that this model is designed for improving all types of signal, it can be used with various operators and has a very extensive coverage capacity. I’m completely pleased with the result of its work.

Dear Jonny, thank you for the feedback. We are glad to know that you liked the product. Best regards, Support team.

 ·  F  ·  Verified Buyer  · 

Expensive but effective

In my opinion, the booster is too expensive. Yes, I understand that is has a number of advanced features like shut-off function, automatic gain control, huge indoor coverage, etc. But does it mean that the price should be so high?

Dear Fred, thank you for the feedback. We offer the best price, if you find the booster with a lower price we will beat it. Kindest regards, support team.

 ·  E  ·  Verified Buyer  · 


I’m totally in love with this device! I bought it for my restaurant, where the level of voice communication left much to be desired and the mobile internet hardly ever appeared at all. The booster changed everything. Now I have stable connection in the restaurant. The audibility is perfect. The mobile internet is satisfactory. I think I will buy another one for my house. By the way, the company has a lot of discounts and personal gifts. That`s nice!

Dear Emma, thank you for leaving a review. We would be glad to see you again. Best regards, Support team.

Good dualband repeater

I think this booster is worth its money. Moreover, if you are using it in business this can be considered a very thoughtful investment. It improves the signal around large area in my hotel. The clients are satisfied. The repeater is compatible with all European operators and improves both voice communication and mobile internet. It has no limitations regarding the number of simultaneous users, which is very important for me.

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

Cables are short

Surely, I’m thankful to the company for a high-quality product and for their caring attitude to the clients. The amplifier works very well, without any errors. It boosts GSM, 3G and even 4G at 900 MHz and 1800 MHz. I use it in the office, which is more than 2000 m2. Yet, there are some points which were a bit disappointing for me. First, the cables – they were too short for my location. The external antenna came with a 10-meter cable and the indoor antenna was supplied with a 5-meter cable. I had to change both the cables for longer ones. And secondly, I didn’t like the design of the model. I wanted something brighter for my place.

Dear Gregory, thank you for the feedback. Your opinion is very important for us. Kindest regards, Support team.

Good booster for business

I own a huge business center. The location of the building isn’t bad in general, but because of thick concrete walls mobile signal in the offices is very weak. My clients used to complain about poor reception inside the building. This situation was becoming worse and worse with every day. When I started to lose clients I realized that something needed to be done. You’d be surprised, but I have never heard of this kind of devices used for signal amplification. A client of mine told me about them and advised to try NS-2500GD. So I followed his advice. The booster is very efficient. It’s very powerful and has an impressive coverage area. Improves all types of signal.

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

Not disappointed at all

I’d like to share my experience of dealing with this model. I read reviews before buying NS-2500GD, and I also asked the tech support if it would be okay in my case. My case is a small store that needed enhanced signals since it was getting hard to work there with all those signal disruptions. I’m not disappointed with my purchase at all, and I am grateful that the managers helped me with this choice. No more disrupted signal!

Hi Lorenzo, and thank you for purchasing from our store. Our team is always ready to help and answer all of your questions! Best regards, Support team.

Simple device

So, what can I say about this booster… This is a very simple model, without even an LCD screen. The functions in all are not bad, it has automatic level control, automatic and manual gain control, the shut-off option. The device really amplifies weak signal inside large buildings. The only minuses for me are the price, which is high in my opinion, and the design, which leaves much to be desired.

Dear Paul, thank you for the review. Your opinion is very important for us. Best regards, Support team.

Bought it for a parking lot

I needed a repeater to install it into a parking lot under a shopping mall. It’s almost obvious that the reception would be really poor under the ground, and it caused inconveniences for the mall customers. Your team stepped in and helped me choose the ideal booster model, which was NS-2500GD. The working range, the signal types and the price – everything that I needed, all in one booster. The price is very democratic indeed, and it pays off really quickly. Saves you energy, boosts signal really well, and is very easy to install without taking up a lot of space. A very good purchase, from my experience.

Hi Sadiyah, and thank you for your review. Our team is always happy to help and answer any of your questions! Best regards, Support team.

Helps in rural area

I bought it for my summer house, which is located in a rural area, plus it’s made of metal. The signal was really weak, even outside the house, and it became downright unusable any time I needed it. Not that it had actually intended to stop working, but it was annoying anyway. I installed The antenna on a pole outside the house. You don’t have to use any poles, I just already had one. The inside antenna went into the central room of the house. Now everything works effectively and nothing is affected by the weather, which is great. I’m not there all the time, but when I am, it’s working great.

Hi Caiden! It’s great that your reception is so much better with our product. Thank you for your purchase at our store.

Works well for me, despite the possible issues

This booster model was my first one ever. I got it a year ago and it’s still working well for me, with no problems at all. It amplifies my Vodafone signal well enough in my area, despite other operators being close to it in the frequency spectrum. I chose this model because of its coverage area, and because it had not only automatic gain control, but manual as well. I wanted it in case there’ll be any troubles with that frequency thing. The LED signals are very convenient and good at showing me what’s going on with the signal repeater, and that is really important due to the possible frequency issues, again. Installing an external antenna wasn’t a problem for me, since I live in a house, I mounted it up on the roof and pulled a wire inside my window. The length that’s included in the pack was enough.

Hello Beulah! It’s good to know that this model was capable of solving your issues. Feel free to contact us if any of them ever occur in the future. Best regards, Support team.

Case Studies

Kieran Chun, Norwich

We were advised a suitable model.

Frankly speaking, it wasn’t an easy task to choose the best model among all the devices available at Mobile-signal-boosters. They offer a huge variety of boosters depending on the indoor coverage and operator’s frequencies. Fortunately, Mobile-signal-boosters’s manager explained us everything we needed to pay attention to and helped us choose the most suitable variant.

Timothy Hassette, Ringwood

The whole set up is not at all complicated!

I would like to thank Mobile-signal-boosters for fast shipping and high quality product they have sold me. The company provides a full set for immediate installation with all necessary details and mountings. They also have sent me a user’s manual with detailed information regarding the set up process and the main features of the device.

Kenneth Nailor, Folkestone

Much needed device if signal problems persist.

I decided that it was time to change the situation with bad signal coverage for better and a signal repeater would be the best decision for our customers to enjoy their 3G internet and GSM connection. It would for sure pay back in a couple of months and, overall, be a convenient thing no matter what.
