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.

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.

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.

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.

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.

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.

Both manual and automatic gain control
The booster has both manual and automatic gain control. These options were very important for me because my previous booster had only automatic signal gain control and it was inconvenient, as I couldn't adjust the system when I needed to. We have had no network interference so far.
Dear Sharon, thanks for the review. We are glad to know that you are satisfied with the product. With regards, sales department.

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.
· Jane Collins (United Kingdom) · Verified Buyer · 13-10-2025
Fine
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.

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.

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.

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.

Improves signal for all UK operators
If you own any business which depends on the quality of mobile coverage, this thing is a must-have. It can improve signal for an unlimited number of users. Improves both calls and mobile internet and does it equally well. The device itself is very compact and doesn’t occupy much space in the room. In my opinion, this is the best booster for all UK providers.
Dear Julia, thank you for leaving the review. Your opinion means much to us. Regards, support team.
· Luella Elliott · Verified Buyer · 17-08-2025
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.

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.
