How it works

Best 4G Signal Booster Nikrans NS2500-GSM+4G-PRO is a perfect solution to boost signal in private houses. Though we guarantee you the highest quality of our devices, to ensure its best performance it is extremely important not to ignore principles of its installment.

While fixing an external antenna of your NS2500-GSM+4G-PRO, pay attention to its direction and conduct an antenna aiming process testing all the possible direction to find the best location that will help you to achieve the highest reception.

For ensuring excellent signal distribution, your indoor antenna should be mounted in a location in the center of your building to cover the widest area possible. If we are speaking about a two-storey house, fix this antenna on a ceiling of a room on the ground floor. It will make the signal cover the first floor as well.

It's a bargain!

The most reasonable price on the Internet. I had to spend some time to install it and make out how it should be assembled, but in the end everything was okay - the signal now is much better than before.

Hello Samantha, thanks for leaving the feedback. We are glad to know that you are satisfied with the order. Kindest regards, support team.

All signal problems solved

My previous booster didn't work for my mobile operator, as it didn't support 800 MHz frequency. The support team helped me choose the right model, which is compatible not only with my operator, but with all UK networks. The manager explained how to install the device properly, and how it works in general. They shipped my order shortly, and just in a few days I was already enjoying the perfect connection. All my signal issues were finally solved.

Hello Samantha, thanks for leaving the feedback. We are glad to know that your problems have been solved. With best regards, support team.

Like the way it works

I took 900+800+1800MHz modification and I like the way it works. Mobile connection with the amplifier is stably 3-4 bars, even in areas where there used to be no connection at all. The model has an LCD screen which is very convenient, it shows some details on the operation of the device.

Dear Harry, thanks for the review. We are happy to know that you like the product. Wishing you all the best, the team of Mobile signal boosters.

Incomplete set

Everything works well, but there were not enough mountings in the set. We couldn’t do with the few fixators and had to buy some more to mount the antennas.

Dear Robert, thank you for the feedback. Please, feel free to contact us in case you need help. Regards, support team.

 ·  K (Denmark)  ·  Verified Buyer  · 

Improved signal

We installed it in a building with strong sound insulation, which unfortunately also blocked the frequency of mobile communications. The external antenna was taken out as high as possible, on the roof of the building, for this we had to buy an additional cable, since the one that came in the kit was short. The internal antenna does its job well. As for the connection, my phone used to catch only a weak GSM signal in the center of the room, and now it even catches the LTE signal. A cell tower is located 3-4 km from the installation place.

Appreciated Kim, thank you for the review. We are grateful for having chosen our product. Kindest regards, sales department.

 ·  T (United Kingdom)  ·  Verified Buyer  · 

Really helps

We have this booster at the office. The signal was received only at the very window and it was weak and that was often lost. As soon as we installed the repeater, turned it on, and that's it, now there is a good signal throughout the office. It works stably, with no errors or disconnections.

Hello Tom, thank you for the review. We are glad to know that the booster has helped you. Regards, support team.

 ·  B (United Kingdom)  ·  Verified Buyer  · 

Be attentive with the modifications

This booster has two modifications - 900+800+2600MHz and 900+800+1800MHz. I first ordered the wrong one, and had to change it. So check in advance which one you need to order.

Appreciated Ben, thank you for the feedback. Feel free to contact us in case you need help. Best wishes, support team.

Intensifies signal significantly

We used to have a very poor signal at our kindergarten. Parents and the staff constantly complained about it. So one day I decided to put an end to this unpleasant situation and I ordered this booster. I’d like to mention that I didn’t install it myself, but in any case, the installation didn’t take too long. Еhe situation has changed dramatically. Everyone has noticed that the level of signal has increased significantly. We have a stable connection around the whole kindergarten, even on the underground floor/ Although mobile internet is weaker there, voice connection is strong enough.

Appreciated Kate, thanks for the review. We are glad to know that your problem has been solved. Kindest regards, sales department.

Good product

I am satisfied with this booster very much. It has everything I wanted – a huge coverage area, three working bands for improving voice connection, 4G internet and even 3G, and a good set of functions. I mean the shut-off option, automatic level control, manual and automatic gain control. The device ensured stable connection around the whole villa, even in the least covered areas. It is very compact and lightweight. I see no disadvantages of it!

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

For GSM and 4G

I use this booster for GSM and 4G improvement. Voice connection is perfect. As for the mobile internet it has become better as well, but still not perfect. It’s possible to make video calls and watch mobile TV, although some online games are still unavailable.

Dear Grays, thank you for the review. Please, feel free to contact us in case you need. Kindest regards, Support team.

No lightning protection

The standard kit included everything except the lightning protection, and I needed it very much! So I ordered it additionally. The set I received contained the booster box and two antennas. The inside panel antenna came with a 5 m cable and the outside one had a 10 m cable. I guess the cable for the indoor antenna may be short for certain premises, so it’s better to order additional cable if possible.

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

I regret that I didn’t install this booster earlier. It makes every minute of mobile communication pleasant and the audibility is so clear that it seems the speaker is just near you. Improves mobile internet as well.

Dear Kate, thank you for the review. We are happy to know that you liked the product. Best regards, Support team.

Too exppensive

In my opinion, the booster is too expensive. Surely, it works without any problems and it really improves poor mobile coverage, but still… The price is too high for such kind of a device.

Dear Bella, thank you for the feedback. We offer the lowest price, if you find a better price for any booster, we will match it. Best regards, Support team.

Good Service

I’m thankful to the company’s manager, who politely helped me find the best model for my office and explained every detail about the installation and functioning of the device.

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

Betters Weak Signal

The device is effective. I use it for bettering 4G, as GSM is more or less okay in my region. The mobile internet now is enough for me to read some news, upload photos, although the videos are loading too slowly for me.

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

I’m using it in my villa

I installed it in my villa. The mobile signal there was awful. It was impossible to speak on the phone. With the amplifier the signal became much better, although it isn’t 100% perfect. There used to be no 4G at all, and now I have mobile internet, although it’s rather slow.

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

Exactly as described

I received my order yesterday, and have already installed it. The kit fully corresponds to the description provided at the website. It includes indoor and outdoor antennas with cables (which by the way, were a bit short), the booster box, manual and warranties. In general, it’s not bad and fulfills its functions rather well. The service at the company is very good as well. I would order here again if I need.

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

Good for large office

I bought the device for my office where the level of mobile signal was very low. First I turned it on in one room, just to see whether it works or not. I was upset to find out that nothing happened – the device was on, it was working, but the signal on the mobile phone didn’t become stronger. Then I installed it as recommended in the manual, placed the outdoor antenna in the direction of the base station, and voila – the signal increased immediately.

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

Can be used in parking lots

I bought it a few weeks ago for the parking lot located underground. The booster really improves weak mobile signal. I used to have two bars on the phone and with this device I enjoy 4-5 bars stable. There even appeared 4g/LTE connection, which previously was only a dream for me. People can watch mobile TV and make video calls from the parking lot. So, I recommend this device!

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

Compatible with all providers

When I was choosing a booster for my entertainment center I paid attention mostly to two criteria – the coverage area (it had to be more than 2000 m2) and the working frequencies (I needed an amplifier to boost not only GSM, but also 3G and 4G). And one more important point – I wanted a booster compatible with all European providers, as my visitors may use different operators. Therefore, I made up my mind to buy Nikrans NS2500-GSM+4G-PRO and I don’t regret. It works very well and effectively improves all types of signal for any provider. Perhaps, the only minus is the long delivery term. Hope that the company will take that into account for future orders.

Dear Charlie, thank you for the feedback. Your opinion is very important for us. We are sorry that the delivery took so much time in your case. Kindest regards, Support team.

I’m pleased

This device is just what I needed. Before buying the booster I settled some moments to be sure that I won’t throw away my money, as actually, the device isn’t cheap at all. So I clarified what frequencies my operator works at – 900 Mhz for calls and 800 Mhz for 4g. This model of the amplifier supports both of them, and even one additional – 2600 Mhz. The coverage area of 2500 m2 was perfect. So I placed an order and their manager practically immediately got in touch with me to confirm it and to provide consultation regarding the installation of the booster. I received it a few days later. My brother helped me with the set up and now I enjoy stable voice connection and mobile internet.

Dear Deborah, thank you for the review. We are glad to know that you are satisfied with the product. Best regards, Support team.

Works just as described

In our case, the booster gives us at least two more signal bars, which is a miracle in our remote area. I know that boosters like these would only be as good as the signal they can find and grab onto, so personal circumstances can vary for different people and different cases, but in our case it works really well! The booster helps us a lot with our internet speed and cell phone calls. The installation was a little bit difficult, because my husband had to climb up to the roof to mount the antenna, but this isn’t the seller’s responsibility at all. The device is really easy to put together indeed.

Hi Etienne, we’re glad that the booster works so well for you. We always want our customers to enjoy strong and stable signal. Best regards, Support team/

 ·  M  ·  Verified Buyer  · 

I’m impressed

In the area where I live data has always been iffy, and our operator couldn’t do anything about it. We couldn’t even think about streaming something without waiting for it to buffer first. Since we installed this booster, life has been much easier. We have a big house and we share it with another family, so we share a booster as well, and it supports all the devices that we all use at the same time.

Hello, Marek! Our boosters can support an unlimited number of devices! We’re glad that it helps you and the people you live with. Best regards, Support team.

Perfect for a supermarket

I work at a supermarket, and we always need good connection so that the working process would go smoothly. Because of the renovations the signal got much worse, so I decided to suggest getting a signal booster to our management. They ordered NS2500-GSM+4G-PRO, and it’s a perfect solution: easy install, fast delivery, and the device is a real work horse. So if you need a good connection at your workplace, this booster is a perfect option.

Hello Jawad, and thank you for your positive review! It’s good to know that our products helped you and your coworkers. Best regards, Support team.

Our office is delighted

This booster model is amazing! Ever since we got it at our office, no one has ever had any issues with phone calls, even though we had them rather often in the past, which was annoying for both us and our clients. We could possibly have even more clients, if we didn’t have those issues. And since we’re a car repair company, receiving questions and orders online was important as well. As you could guess, phone calls weren’t our only problem. But we had an idea of a signal booster rather soon, and now we have NS2500-GSM+4G-PRO at our office. The fun thing is that our 4G hotspot now requires less battery power, because it now has to connect to the repeater antenna instead of the faraway cell towers. We’re located quite far from the big city, near a highway, but the signal is still amplified really, really well.

Hi, Suzanne! We’re always happy to help! It’s very good that this repeater model works so well for your company office. Best regards, Support team.

Case Studies

Jacob Bedwell, Chester

Signal issues may become really irritating!

O2 is one of the most demanded mobile operators in our country. It has a wide range of modern mobile services on offer and, what is more, it attracts users with constant bonuses and discounts. Actually, these are the main reasons why I have been their subscriber for so long. Nevertheless, when my company changed the location, we had to face some O2 signal issues. Fortunately, these inconveniences immediately disappeared when we installed a signal booster.

Frank Wesson, Liverpool

Thanks for your assistance!

Not so long ago I purchased a mobile phone signal booster at Mobile-signal-boosters to improve Asda (and other operators') poor signal in the hotel I own. The company’s manager gladly helped me choose the model which best suited my needs. The indoor coverage is extensive enough for the whole area of the hotel. The device supports the operator’s frequencies and works without errors.

Trent Irby, Bath

Worth purchasing!

I would like to emphasize that I was fully pleased with the attitude which the support team of Mobile-signal-boosters demonstrated towards my problem. They were ready to give me advice on any question, be it the choice of the model or the installation of the mobile signal booster. Their managers are one of the most caring and attentive staff I have ever met!
