Specification
How it works
Although the installation of the signal amplifier Nikrans NS350-GSM+4G/LTE is very fast and simple, there are still a few things to bear in mind during the set up process. First make sure that your outside antenna is able to catch any kind of signal. While mounting, take into account the location of all obstacles on the way between the signal and the outside antenna. As far as the indoor antenna is regarded, it’s better to mount it somewhere in the center of the building because only in this case every part of the area will receive equally improved signal. If you have any questions regarding the installation or the functioning of the device look through the manual provided in the kit or feel free to contact our support team.
Another GSM 4G amplifier with the similar features is NS550-GSM+4G signal repeater that is used for Spanish networks and other EU countries.

More than just effective
This booster is a real salvation for those who have to work in office with poor mobile coverage and have no mobile internet at all. It changed my life and my business. Now I’m always in touch when at the office. It’s great!
Dear Eva, thank you for the review. We would be glad to see you next time. Best regards, Ыupport team.

No problems
The service at the company is welcoming and nice. After I have placed an order at the website, their manager got in touch with me. He clarified a few details concerning the frequencies my operator used and the area I needed to cover. The booster is dualband, but you can choose the LTE band you need. In my opinion, the only minus is that you cannot choose the colour of the booster itself, as it’s available only in black.
Dear Peter, thank you for the review. We are happy to know that you are satisfied with the product.

Good present
I bought this amplifier for my parents. They live in the village, not far from the town, but the quality of mobile signal there leaves much to be desired. This booster can be used for both improving phone calls and 4G, although my parents mostly use it to better the voice connection. Nevertheless, I thought that it would be a good idea to buy a more universal booster model, which will be able to refine mobile internet as well. This is a good option!
Dear Lexi, thank you for the feedback. We are glad to know that you are satisfied with the result. Kindest regards, Support team.

Best booster for my needs
I've got a large family, and we all use different mobile operators, but the one thing we had in common about mobile connection was its poor quality. So I needed a booster to amplify signal for EE, O2, Vodafone, and Virgin mobile, and with a coverage area of about 300-350 m2. I didn't want to spend much time on the search for the suitable amplifier, so I just called the sales team and they helped me with the choice. NS350-GSM+4G is just what I needed, the best booster I've ever had. The quality is good and the operating is smooth and efficient.
Hello George, we are glad to receive your feedback. Thank you for choosing our product. With best regards, sales team.

Good equipment
I bought this booster to replace the older model which I had, as it had been broken by my children. So what do I like about it? First, the effectiveness. The result of its work is amazing. The signal around the house has become much more stable and strong. Secondly, I like the design, which is very compact and lightweight. And surely, I liked the attractive price offered by the company.
Dear Oscar, thank you for the review. We are glad to know that you are pleased with the purchase. Kindest regards, Support team.
· Joe · Verified Buyer · 17-03-2023
Pleasant surprise
I hope that I will never need to buy a second booster (I hope that my mobile operator will do something about our awful connection or at least that my NS350-GSM+4G will function for many-many years). But if I need to buy the second one, I am sure that I will order it on this website. My amplifier arrived even earlier than I could expect, it was well-packed, and there was a detailed manual in the box. So, after reading all the instructions, I installed it completely on my own. It was a pleasant surprise.
Dear Joe, Thank you for the review, we greatly appreciate it. Kind regards, Support team.
· Maddison Martin · Verified Buyer · 16-03-2023
Superb!
I can’t imagine my life without this device any more. Using my mobile phone has become such an enjoyable thing just because now I never get nervous about signal problems or slow internet.
Dear Maddison, thank you for the review. Keep on enjoying it! Kindest regards, Support team.
· Phil · Verified Buyer · 13-03-2023
No manual in the set
The installation of the device caused a lot of problems to me, as there was no user’s manual in the standard kit and I am an absolutely inexperienced user of mobile boosters. So I had to surf the net and I spent plenty of time trying to find instructions about the installation. Then I called the support team, they made an excuse and explained me everything. After the installation I just plugged the device in and it started to work.
Dear Phil, thank you for the review. Feel free to contact us whenever you need. Best regards, Support team.
· Mark Delton · Verified Buyer · 11-03-2023
No LCD
Everything is okay. It’s only a pity that the booster has no LCD screen. But I think, that in this case it would have cost much higher.
Dear Mark, thank you for the feedback. Your opinion is very important for us. Kindest regards, Support team.
· Sarah Miller · Verified Buyer · 06-03-2023
Everything is Ok
The device is good. It works very well, without any errors. I had read the user’s manual in advance, so the installation didn’t take long and wasn’t troublesome at all. Now I have stable voice and data connection at work!
Dear Sarah, thank you for the feedback. Your opinion is very important for us. Kindest regards, Support team.
· Ben A. (United Kingdom) · Verified Buyer · 05-03-2023
The most powerful device
Finally I got what I wanted. The level of GSM signal is fantastic with this booster. The speed of 4G literally tripled after switching on in the house, even before I took it out into the yard. YouTube is working without interference, films are loaded with lightning speed. Thanks to the team of Mobile signal boosters.
Hello Ben, thanks for the feedback. We appreciate your opinion very much. Regards, support team.
· Sarah London · Verified Buyer · 03-03-2023
Simple installation
I liked the product. It’s simple to install and the working principle is understandable. My husband carried out the installation himself. We had read the manual in advance, so we had no problems at all. There is a light indicator on the repeater, and when it turns on it means that the set up has been carried out correctly and without errors. No additional software was needed. It’s a plug-and-play device.
Dear Sarah, thank you for the review. Keep on enjoying the product. Kindest regards, Support team.
· Gerard (France) · Verified Buyer · 17-02-2023
Works with all French providers
We use the booster to amplify GSM and 4G Orange signal, but it’s compatible with all French operators. The indoor coverage is enough for our house of about 300 m2.
Hi Gerard, thank you for the feedback. Looking forward to your next visit. With best regards, support team.
· Max Clean · Verified Buyer · 16-02-2023
Had some issues
I had some issues with this booster. The power supply of the device was normal, but the ALM light was flashing all the time. I didn’t know what to do, so I decided to call the support team. They advised me to check whether all the connections were connected rightly and to adjust the positions of the outside and inside antennas. It turned out that the horizontal distance should have been 75 feet or more, and the vertical distance should have been 20 feet or more. After I have changed the locations, everything was all right.
Dear Max, thank you for the review. Please, contact us whenever you need. Kindest regards, Support team.
· Emanuel (Spain) · Verified Buyer · 11-02-2023
High-quality enhancement of mobile communication
I like the booster. It’s compact and convenient to install and to use. I didn’t buy any extra-elements, everything was in the standard set. Installed it myself, as there was nothing complicated. The coverage in the office became better indeed. Even at the underground level we have some signal, the phone catches 2-3 bars.
Appreciated Emanuel, we are glad to receive your feedback. Thank you for choosing our product. Wishing you all the best, sales team.
· Irene Maxwell · Verified Buyer · 04-02-2023
Good company
I promised to come back here and I did so. The company is very reliable. This is the third time I’m buying an amplifier here. The staff is always polite and the products are of good quality.
Dear Irene, thank you for the review. We would be glad to see you again. Kindest regards, Support team.
· Nina (Greece) · Verified Buyer · 26-01-2023
Useful
I advise buying this booster if you don't want to suffer from signal problems and want to enjoy stable mobile coverage. This will suit both for apartments and offices, provided they are not very large. The device is useful and I think that the price is affordable.
Dear Nina, we are grateful for your review. Thank you for choosing our product. Wishing you all the best, the team of Mobile-signal-boosters.co.uk.
· Bob Moore · Verified Buyer · 25-01-2023
Good service
I’m so thankful to the support team for their patience and caring attitude. They were so polite. After I placed the order they immediately got in touch with me in order to clarify the details. The product was sent without delay. Good job!
Dear Bob, thank you for the feedback. Your opinion means much to us. Best regards, Support team.
· Hallie Smith · Verified Buyer · 22-01-2023
2 bands
This booster is very simple, nevertheless it’s effective at the same time. I bought it for my friend, as he often complained about poor mobile signal at his countryside house. The coverage of 350 m2 is enough for his medium-sized house. The booster works at two frequencies at a time – 900 MHz and one of standard LTE bands 2600MHz or 800MHz. So you may choose and it’s great. My friend is happy about the result!
Dear Hallie, thank you for the review. We are glad to know that your friend liked the booster. Kindest regards, Support team.
· Davis Morgan · Verified Buyer · 20-01-2023
No necessary accessories for mounting
I ordered the booster last week and I received it without the necessary accessories for mounting. I was a bit disappointed and I had to get the mountings myself.
Dear Davis, thank you for the feedback. We are so sorry for you. Please feel free to contact us in case you need help. Kindest regards, Support team.
· Peter Thompson · Verified Buyer · 25-11-2022
Nice
I am fully satisfied with this booster. It has auto and manual gain control, auto level control and shut-off function which is needed to avoid self-oscillation. Good product! I recommend!
Dear Peter, thank you for the review. We would be glad to see you at our store again. Kindest regards, Support team.
· Daniel Brown · Verified Buyer · 21-11-2019
Ensures stable connection
I purchased this repeater on my brother’s advice. He has one at his office and he is satisfied with the result of its work. His booster covers up to 1000 m2 and it’s much more expensive than my NS350-GSM+4G with the coverage capacity of 350 m2. The repeater works well, I have no more signal issues. There even appeared smooth 4G Internet in the rooms where I could hardly ever use mobile internet.
Dear Daniel, thank you for the review. We would be glad to see you at our store again. Kindest regards, Support team.

Case Studies
Even with our signal issues, it would have been very inconvenient for my company to change tariff plans and/or look for another operator that would possibly have better signal at our office. Or wouldn’t. So we needed to improve the existing signal, and Mobile-signal-boosters, recommended by one of our employees, promised us they could easily do it in our case and help us work efficiently, using our internet and cell phones again.
James Hovey, SwindonMy fiancé is a Giffgaff subscriber, and after she moved in with me, we started noticing that there were terrible Giffgaff signal issues at my place. I use another operator’s services, so we never noticed that before, until she had to use her internet and cell phone in my apartment full-time. Giffgaff cell towers are pretty far away from the region I live in, that’s why their signal couldn’t be caught very well.
Max Butterworth, Bury St EdmundsAll our fears about the quality disappeared after we received our parcel from Mobile-signal-boosters store. The delivery was very speedy indeed, and all the parts showed no signs of defects. The repeater itself and all of the details it required for working were absolutely intact, and packed nicely and safely. We also found a user instruction inside the box and were very happy with how extremely time-saving it is.
