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.

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/

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.

Thanks for your assistance!

Not so long ago I purchased a mobile phone signal booster at 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 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!
