NS-2500GDW is your ultimate answer for boosting GSM and 3G signals in areas with poor connectivity. The cellular phone signal booster for home is distinguished by the tech design and the latest software that enables it to cover areas of up to 2000m2 (21500 ft2). It is suitable for providing unsurpassed GSM and 3G coverage in spacious villas, offices, supermarkets, conference halls, and underground areas, etc.

The booster amplifies signals at three frequencies at the same time: GSM 900 MHz & 1800 MHz and 3G 2100 MHz, all of which are compatible with network providers in Ireland and the United Kingdom.

Alongside, the booster is also able to amplify 4G/LTE signals at 1800MHz on condition that your provider supports 4G at this frequency.

Here are some of the most unique features of this device:

  • Automatic Level Control that serves the purpose of avoiding signal interference.
  • Automatic Gain Control for creating favourable signal conditions.
  • Manual Gain Control for advanced users looking to control the gains manually.
  • Shut-off function for protecting the booster from malfunctioning due to incorrect installation or self-oscillation.
  • CE and RoHS certificates for ensuring 100% safety in usage.

Having to stabilize GSM, 3G and 4G connectivity all the time is quite frustrating in areas with poor network reception. Therefore, buy this model now and forget about all the nuisances caused by poor quality calls and slow Internet speed!

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

We highly recommend to follow the principles of its installment. An external antenna is usually mounted on the roof of the building or via a window on the top story. Please pay attention to its direction in order to achieve the highest reception. The indoor antenna should be mounted on the ceiling in order to ensure better distribution of the amplified signal. Both antennas should be connected with a coaxial cable to the base unit. If you want to cover several floors simultaneously (especially for multi-storey buildings), we recommend to purchase additional indoor antennas and splitters that will help to distribute the boosted signal across the remote area.

No issues with this store

I offered to purchase this repeater for the office where I work, and my bosses appreciated that advice. I actually had a similar device, but with a different working range, at home, so I don’t really doubt its abilities. Both home one and office one work well, without any problems, and require no maintenance. And the main thing is that the signal problems are gone now, and the signal (GSM and 3G) is strong and stable. I’d even say smooth.

Hi Sara! It’s good to know that you’re so satisfied with our products. We’re glad we could help make the signal better. Best regards, Support team.

Worth the money

Even if it seems a bit too expensive at first, having good connection is crucial for any business, and it will pay off very soon. It really launches 4G and GSM signals almost into space, and the connection is very stable.

Hi, Amir! We’re glad that we could help you with making the signal stable. Thank you for this review. Best regards, Support team.

I installed it in a club that’s located in the underground premises. A good place for a club, but the signal was horrible. Not that people make too many calls inside due to the music, but it’s still necessary for visitors’ safety.

Hi, Oran! Thank you for purchasing from our store. It’s good to know that you’re enjoying our product. Best wishes, Support team.

Solved the reception problem

We opened a conference hall inside a really old building, but the internet and cell phone reception turned out to be quite poor inside of it because of the thick walls. This booster is a great solution for that case. It catches the signal outside really well and distributes it inside the conference hall. All of the guests are satisfied with the signal quality. This booster works with many devices at once, which is great for public places like that.

Hi, Kain! Thank you for the positive feedback. We’re glad that our booster helped you solve the problems! Best regards, Support team.

Not bad

I changed my older model for this one. NIkrans NS-2500GDW isn’t bad. It’s more powerful in comparison with my previous booster, but I have to admit that the cables in the kit are too short and the model has no LCD.

Dear Ronald, thank you for the feedback. We would be glad to see you again. Best regards, Support team.

Doesn’t emit radiation

The booster is effective, and I like the fact that it doesn’t emit radiation, so it’s absolutely safe for my clients. I think it’s worth the money you give.

Dear Stephen, thank you very much for the review. Hope to see you again at our store. Best regards, Support team.

I bought the booster for the children’s entertainment center I own. The walls of the building create obstacles on the way of the signal, so it used to be very weak inside. With the device the signal is stable. In my opinion, it’s effective.

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

Increases signal

To cut the long story short – it’s working well and it really increases weak reception around huge areas up to 2000 m2. The only minus is the price, which is very high.

Dear Abby, thank you for the review. Your opinion means much to us. Best regards, Support team.

Good for Parking Lot

I bought it to increase poor signal at the parking lot located underground. Fulfils the task without any difficulties. The level of mobile signal is stable, there are no more reception issues.

Dear Lucy, thank you for the review. We are glad to know that the product is working well. Best regards, Support team.

Check the coverage area

I bought this model by mistake. Actually, I don’t even know whose fault it was – mine or the company’s. I needed an amplifier for my private house with an indoor coverage of about 200 m2, and the support manager sent me this one with an indoor coverage of 2000 m2. That’s huge! I think that we have misunderstood each other. Fortunately, they agreed to change it as they have a 30-day return policy.

Dear Chloe, thank you for leaving a feedback. We are sorry for the misundersatnding that have occured and glad that the problem was resolved. Kindest regards, Support team.

Good Company

I’d like to thank the supplier for good quality of the product and their perfect job and service. Although the delivery time was a bit longer than I had expected, it didn’t spoil the general impression. The company provided a 3-year warranty for the product, and the booster they sent me, meets all European quality standards. The support team was always ready to answer the questions and to provide assistance.

Dear Peter, thank you for the review. We are glad to have been helpful to you. Kindest regards, Support team.

I have been using this device for half a year. Haven’t noticed any drawbacks yet. It improves all types of signal (GSM, 3G, 4G) around the area of about 2000 m2. The working frequencies of the device are 900 MHz for GSM, 1800 MHz for 4G, and 2100 MHz for 3G. These bands are supported not only by my operator but also by many other European providers. The booster is convenient to use as it doesn’t require any additional software or equipment, the company sent me everything needed for the installation. As for the set up process itself, it’s rather understandable after you have read the installation manual provided.

Dear Mary, thank you for the feedback. We are happy to know that you are satisfied with the product. Best regards, Support team.

Nice Tri Band Booster

I would like to share my opinion about this device. I bought it four months ago for my supermarket, which is located underground. The signal there was very poor. It was impossible to make calls or to use mobile internet. People had to go upstairs in order to use their mobile phones. After the installation of Nikrans NS-2500GDW the situation with the signal changed considerably. The phone always shows full bars, only sometimes in the most remote zones it may show 2-3 bars, but still, it’s enough to hear the speaker on the phone clearly. As for the mobile internet, it appeared even in the areas, where it was absent. I’m pleased with the result!

Dear William, thank you for the review. We are glad to know that your problem has been solved. Kindest regards, Support team.

Helped us with our terrible signal

I’ve had absolutely terrible signal at my new office after our company moved in. As you can tell, this isn’t good for the working process at all, so I had to find the solution, and I found it1 the delivery was really quick, and it was a vital necessity for us. The repeater installation is very easy, no help is required from any other specialists, I actually mounted it onto the ceiling myself. The signal is smooth and stable now!

Hi, Kaiya! It’s good to know that your office can now work having stable signal. Contact us if you have any more questions, we’ll be happy to help! Best regards, Support team.

Useful device

If you want to buy this model, pay attention to the frequencies first, and make sure that you know the exact frequencies that your operator works on. This device is really great and it amplifies the signal very significantly, I now have signal where I previously couldn’t catch it at all. The support team is very friendly and they answered all of my questions. I loved buying from this store and recommend it to anyone who’s reading this.

Hello Aleena! We’re happy that you liked our store and the work of our tech support team. Thank you for writing a review! Best regards, Support team.

Increases the internet signal significantly

Purchasing this signal repeater was a very short and easy way from having to endure constant buffering while trying to watch videos in 360p (and everyone knows that this definition is too low even for the phone screen nowadays) to being able to watch HD videos and use online streaming services. The repeater increases the GSM signal as well, but it wasn’t too critical for us (me and my wife), since we don’t have too many phone calls in our lives. Yet we thought it would be useful to have a booster that can amplify all three signal types at once – just to be sure that everything will be ok. But the internet was the most important thing. Signal troubles were driving us absolutely mad before, because we love to spend our evenings watching stuff online, and we’re really happy to finally have fast enough internet speed in our rural area.

Hello Tyler! We’re very glad that our product helped you and your wife so much. Rural areas can be a lot of trouble for the signal! Best regards, Support team.

Case Studies

Lionel Hansen, Liverpool

There were constant signal problems in our office.

It’s not a secret that practically all business conversations in the modern world take place on the phone. Therefore, good quality of mobile connection plays an important role in any business. When my company changed the location, we noticed that O2 mobile coverage is imperfect there. The only way to refine O2 poor signal in the office was to install a booster.

Warrick Aplin, Bradford

The booster conforms to all our requirements.

When I was choosing an amplifier to improve poor signal in the museum, I paid attention to numerous factors. First of all, that was the coverage area. Secondly, the working frequencies. And finally, the way the device looked like. The model I have ordered covers the whole area of the museum. It is compatible with all operators. Moreover, it is very nice and stylish.

Pleasure to deal with this online store.

It was a pleasure for me to work with Mobile-signal-boosters.co.uk team. The company really cares for every client’s problems trying to provide the best solution possible in the shortest terms. They provide manuals and warranties for all their products which is undoubtedly a great advantage. I received answers to my questions, as well as tips regarding the choice and the installation of the booster.
